The Federal Battery Rebate, otherwise knows as the Government’s $2.3 billion Cheaper Home Batteries Program offers roughly 30% off battery storage systems to Australian households. When it launched in July 2025, no one predicted batteries would start flying off warehouse shelves at the pace it did and energy retailers like Origin are warning: we could hit the rebate cap by mid-2026.
In this article, you’ll get a clear breakdown of:
What’s driving this spike in battery installs
How close we really are to the rebate running dry
What could happen next — and what that means for you
What Is the Federal Battery Rebate and Why Is It So Popular?
If you’ve looked into adding a solar battery lately, you’ve probably heard about the Cheaper Home Batteries Program (CHBP) — a federal rebate launched in July 2025 to help more Australians afford energy storage.
The rebate covers roughly 30% off the cost of an eligible home battery system (up to 50kWh). For most households, that equates to $2,000–$4,000 back, depending on the battery brand, size, and your energy setup.
The response has been massive.
In the program’s first month alone, 19,592 batteries were installed.
By early September, that figure had climbed to 43,500+ installations, averaging around 888 installations per day.
By November, Energy Minister Chris Bowen reported 136,000 batteries installed since July — more than double the typical yearly total before the rebate.
One chart shared by The Today Show showed some of the most active states in the first month — with NSW and QLD leading, followed closely by VIC and SA.
So what’s behind this rush?
For many homeowners, it comes down to affordability and timing:
Batteries have become significantly cheaper over the past two years.
Add roughly 30% rebate on top, and the payback period has dropped for most households.
With power prices rising and feed-in tariffs falling, many people now see a battery as the best way to self-use their solar energy and reduce peak-time grid reliance.
How Fast Are the Funds Being Used?
When the federal government announced the Cheaper Home Batteries Program with a $2.3 billion budget, it was pitched as a long-term incentive — running until 2030, however, this timeline now looks extremely optimistic.
According to SolarQuotes, an analysis which examined Clean Energy Regulator data and installation trends:
Over 90,000 systems had been processed for rebate claims as of 31 October 2025, with more pending.
That early wave of installs had already chewed through around $678 million in just four months.
At that pace, the entire $2.3 billion could be exhausted in 13–14 months — pointing to a mid-2026 cutoff.
Energy Minister Chris Bowen said 125,000 households had installed batteries by mid-November, not just the 90,000 that had been fully processed for certificates. That’s a 21% higher figure, and it changes the maths.
SolarQuotes’ revised analysis, using Bowen’s higher number, suggests the rebate could be fully allocated by June 2026 — or as early as May if demand keeps accelerating.
The driving force is not just the rebate itself, but also:
A shift in homeowner behaviour — people want to keep their solar energy instead of exporting it for a few cents.
Falling battery prices and rising energy bills.
A growing awareness of blackout protection, especially in summer.
Another key factor accelerating the depletion of funds is the increasing average size of battery systems. Since the rebate is calculated based on usable battery capacity, the shift from an assumed average of 17kWh to more than 20kWh per system means larger payouts per installation than initially projected.
This combination of high uptake and growing system sizes has led some analysts to conclude that the program’s 2030 end date is unlikely to be realised without further government intervention.
Could the Federal Battery Rebate Be Extended or Adjusted?
It’s possible — however not guaranteed.
The federal government hasn’t yet announced any top-up or structural changes to the Cheaper Home Batteries Program. However, with uptake far exceeding early expectations, both energy experts and industry groups are now openly calling for action.
Potential outcomes to look out for
Reducing the Cap per Household?
One suggestion from SolarQuotes is to cut the maximum eligible battery size for the rebate — not to shrink rebates for typical households, but to slow down uptake at the top end.
Currently, you can claim a rebate for up to 50kWh of usable storage — far more than most homes need. Reducing that cap to 25kWh could stretch the funding further while still covering 99% of residential use cases.
The upside? More households could benefit.
The risk? It might discourage larger households or early adopters wanting future-proofed systems — particularly those aiming for full off-grid capability or participating in VPPs.
More Rules, More Problems?
Some experts warn against over-complicating the program.
If policymakers try to engineer the “perfect” battery rollout through stricter sizing, inverter pairing rules, or eligibility tests, they risk:
Slowing installs
Creating confusion
Opening new loopholes for dodgy operators to exploit
As SolarQuotes analyst Ronald Brakels points out: “Making the scheme more complex can do more harm than good… We may get better results just by requiring installers to inform homeowners of drawbacks.”
What’s Most Likely?
Given the federal battery rebates popularity — and its positive impacts on grid reliability and household bills — some form of adjustment or extension seems politically smart. However, until it’s announced, homeowners are in a race against the funding clock.

Is AlphaESS a Reliable Battery Brand?
When it comes to batteries, reliability isn’t just about what’s on the spec sheet — it’s about how a system performs in real-world conditions, how well it’s supported locally, and whether it holds up over time. So, how does AlphaESS stack up?
Their systems are listed with the Clean Energy Council and are widely used in residential installations. In terms of adoption, AlphaESS batteries have been consistently listed among the top five brands, particularly among Chinese manufacturers according to Sunwiz and PV Magazine, though exact rankings by number of systems versus kWh capacity vary. That doesn’t automatically mean they’re the best — but it does mean they’re proven and widely deployed.
Independent Testing (ITP Renewables)
AlphaESS systems have been tested as part of a long-term battery trial run by ITP Renewables, funded by the Australian Renewable Energy Agency (ARENA). This trial cycles batteries multiple times per day to simulate real-world use over years in a compressed timeframe.
One of Alpha’s early models, the M48100, was included in this program. While it showed some performance restrictions after extended testing, it’s important to note that:
This was a first-generation model from more than 7 years ago
The current SMILE series is significantly more advanced
AlphaESS themselves acknowledged and addressed the limitations found
Since then, the company has made noticeable improvements in battery chemistry, thermal management, and firmware control — and there haven’t been any flagged reliability issues with newer models in public testing reports.
AlphaESS Battery Pros and Cons: An Honest Look
Like any energy storage system, AlphaESS batteries come with trade-offs. They’re popular in Australia, especially with homeowners looking for an all-in-one, cost-effective battery setup — but popularity doesn’t always equal perfection.
Here’s a clear, honest breakdown of the main advantages and limitations of the AlphaESS SMILE series, based on installer feedback, user reviews, and publicly available data.
Pros
Cons
Competitive Pricing – Often more affordable than brands like Tesla or Sonnen.
Mixed Installer Feedback – Some report slow support response during installs or faults.
Limited Inverter Output – 5kW inverter may not suit large homes or high-usage businesses.
Modular & Scalable – Easily expand battery capacity over time.
Early Model Performance Issues – Older units like the M48100 had issues during testing.
VPP Ready – Widely accepted in Virtual Power Plant programs.
Australian Support Office – Based in Chatswood, NSW for warranty and tech queries.
Should You Consider AlphaESS for Your Home or Business?
If you’re comparing battery brands in 2025, AlphaESS deserves a spot on your list — especially if you’re looking for an affordable, all-in-one system that’s ready for VPPs and comes with local support.
The SMILE series in particular hits a sweet spot for many homes and small businesses: it’s modular, scalable, and integrates a hybrid inverter to keep things simple. For new solar installs, the DC-coupled SMILE-G3-S5 is one of the more efficient systems on the market. And for those retrofitting storage onto existing solar, AlphaESS offers AC-coupled options that are flexible and cost-effective.
But it’s not the right fit for everyone. If your home has high peak energy loads or if you want ultra-fast support turnaround, you might want to consider higher-capacity inverters or brands with a more established service network.
At the end of the day, AlphaESS isn’t trying to be a premium brand — it’s aiming to deliver solid performance at a fair price, with systems that are widely accepted across Australian incentive schemes and VPPs.
The takeaway? If you’re price-conscious, looking for a system with local support, and value flexibility, AlphaESS is worth a close look. Just make sure you’re working with an installer who knows how to set it up properly — and who’s transparent about what to expect if you ever need support.

Lenergy can walk you through your options and provide honest, tailored advice
You’ve probably heard the hype around the Tesla Powerwall 3. It’s well-known, widely marketed, and packed with smart features. Then there’s Pylontech — a strong performer with a growing reputation among Australian installers for reliability and value.
So which one actually makes more sense for your home?
At Lenergy, we’ve installed both systems and helped hundreds of homeowners weigh up this exact decision. We know the questions people ask, the numbers that matter, and the gotchas you don’t find in the glossy brochures.
This article gives you a side-by-side breakdown of the Tesla Powerwall 3 and the Pylontech Force H3X. You’ll learn how they compare on performance, price, compatibility, and more so you can make a confident, well-informed decision about which one (if either) is right for your solar setup.
If you’ve been researching solar battery options in 2025, chances are you’ve come across both the Tesla Powerwall 3 and the Pylontech Force H3X. These two batteries come up in conversations with homeowners for a few good reasons:
They’re widely available in Australia
They offer serious backup potential
They support flexible solar system configurations
And they’re eligible for current rebates and VPP programs
That said, they’re very different systems.
The Tesla Powerwall 3 is a high-output, all-in-one battery with an integrated hybrid inverter, allowing it to be used in both AC- and DC-coupled systems. It’s often chosen by households looking for strong backup performance, smart home integration, and a clean, consolidated design that minimises wall clutter.
The Pylontech Force H3X also features an integrated inverter, offering flexibility to operate in both AC- and DC-coupled configurations. It’s a modular system, which makes it ideal for homes that want custom sizing, more inverter options, or the ability to start small and expand over time — whether you have a single-phase or three-phase setup.
So if you’re trying to decide between them, this isn’t about which battery is “better.” It’s about which one fits your home, your usage patterns, and your long-term energy goals.
Capacity, Scalability & Suitability
When it comes to batteries, capacity isn’t just about how big it is — it’s about how well it fits your household’s energy habits, future plans, and available space. Here’s how these two batteries compare.
Tesla Powerwall 3: Fixed Capacity, High Output
The Powerwall 3 offers 13.5kWh of usable capacity in a single unit, with the ability to stack up to 40.5kWh (3 units). This covers most medium to large households — particularly if you’re trying to cover both night-time usage and power outages.
What’s different about the Powerwall 3 is that it includes a fully integrated hybrid inverter, making it suitable for both new solar systems and retrofits. But it’s not modular — if 13.5kWh isn’t quite enough, you’ll need to add to a whole second 13.5kWh battery unit, taking you to 27kWh of storage.
Pylontech Force H3X: Modular and Flexible
The Force H3X is built for customisation. Each battery module delivers 5.12kWh nominal capacity, with 4.864kWh of usable storage.
You can stack:
Up to 20kWh usable on a single-phase tower
Up to 35kWh usable on a three-phase tower
Multiple towers can be installed together for even larger systems.
This makes it a smart choice if:
You’re looking for better value for each kWh of storage
You want compatibility with both single-phase and three-phase systems
In short: Powerwall suits those who already have the Tesla ecosystem (EV charging point/car) and are ok with paying a premium price for a premium battery. Pylontech suits those who want flexibility in system sizing at a more affordable price point, or households with either single-phase or three-phase supply looking for full backup or large-scale solar and battery setups. It’s also a proven name in the Australian battery market, with over a decade of local presence and performance.
Performance & Backup Power
When the grid goes down, not all batteries perform the same. Understanding each battery’s output, responsiveness, and blackout support can help you decide which one actually keeps your home running when it matters.
Tesla Powerwall 3:
The Tesla Powerwall 3 supports up to 20 kWh DC of solar and provides up to 11.5 kWh AC of continuous power per unit, which is extremely high for a residential battery.
This means:
You can run most of your home during an outage, including large loads like air conditioners or pool pumps (depending on your setup)
You’re less likely to need to manually manage which circuits stay powered during blackouts
Tesla’s Powerwall also comes with a built-in backup gateway, which automatically detects outages and switches to battery power almost instantly. It’s a fully integrated backup solution — no need for external switches or special wiring in most cases.
Pylontech Force H3X:
The Force H3X can be paired with Pylontech’s own inverters, which are available in both single-phase and three-phase models. At the time of writing (November 2025), the single-phase inverters (5kW and 8kW) are already in use, while the three-phase options (10kW, 12kW, and 15kW) are expected to receive CEC approval by the end of 2025.
What this means for you:
With Pylontech’s inverters, your backup power is limited to the capacity of the inverter size.
These inverters are purpose-built for use with the Force H3X, streamlining setup and monitoring
Inverter & System Type: AC & DC Coupling
One of the biggest technical differences between these two batteries is how they connect to your solar system — and it’s something many homeowners overlook. It affects everything from system design to efficiency, installation costs, and future flexibility.
Tesla Powerwall 3:
The Powerwall 3 includes a fully integrated hybrid inverter, which makes it capable of both AC- and DC-coupled configurations.
In AC-coupled mode, it can be added to virtually any existing solar setup — making it a simple option for retrofits without changing your current inverter.
In DC-coupled mode, the built-in inverter allows you to connect up to 20kW of solar panels directly to the system. This setup improves efficiency by reducing the number of energy conversion steps and enables tighter integration between your solar and battery.
This dual capability gives the Powerwall 3 added flexibility for both new installations and upgrades.
Pylontech Force H3X:
The Pylontech Force H3X is designed to support both AC- and DC-coupled configurations, offering flexibility for a wide range of system types. Pylontech’s own inverters are available in single-phase (5kW, 8kW) and three-phase (10kW, 12kW, 15kW) models (pending CEC approval for three-phase as of November 2025).
In a DC-coupled setup, the battery connects to your solar system before the power is converted to AC, offering:
Higher overall efficiency
Improved energy yield, particularly in new builds or inverter upgrades
In AC-coupled mode, the Force H3X can be integrated into existing solar systems, making it a viable retrofit option — especially with the right inverter setup.
This dual-coupling capability makes Pylontech a versatile choice for both new and existing homes, with more control over sizing and design.
Warranty, Lifespan & Battery Chemistry
Not all warranties are created equal — and neither are battery chemistries. These details can affect how long your battery lasts, how safe it is, and what kind of support you’ll get if something goes wrong.
Tesla Powerwall 3: LFP Chemistry, High Output
The Powerwall 3 uses Lithium Ferro Phosphate (LFP) chemistry — known for its thermal stability, long cycle life, and enhanced safety. It’s a shift from earlier Powerwall versions, which used NMC chemistry.
LFP batteries are:
Less prone to overheating, making them safer in hot environments
Capable of more charge/discharge cycles, giving them a longer lifespan
Tesla backs the Powerwall 3 with a 10-year warranty, promising at least 70% capacity retention. Combined with its 30kW peak power output and smart features, it offers a blend of durability and performance that suits most residential setups.
Pylontech Force H3X: LFP Chemistry, Longer Lifespan
The Force H3X uses Lithium Iron Phosphate (LFP) — a chemistry known for:
Greater thermal stability (safer in high temps)
Longer cycle life, often exceeding 8,000+ cycles
Pylontech backs this with a 10-year warranty too. For homeowners prioritising longevity, LFP is often the preferred option.
Warranties with Pylontech may involve the inverter manufacturer or installer as part of the support chain — so it’s worth asking your installer how warranty claims are handled.
Price & Installation Considerations
For most households, price is a major factor in choosing a battery. Here’s how the Powerwall 3 and Pylontech Force H3X compare on upfront pricing, installation complexity, and rebates.
Tesla Powerwall 3: Premium Price, Simple Install
The Tesla Powerwall 3 installed price in Australia typically ranges from $15,000, depending on your installer, location, and whether it’s part of a full solar package.
Because it’s AC-coupled with a built-in inverter, installation is usually straightforward for both new and retrofit systems. That said:
It’s not modular, so you need to add 2 or 3 full units if you want more storage
Some installations may still require a back-up switchboard upgrade (but this for just Tesla)
Tesla’s strong brand reputation and integration with solar + EV setups are part of what you’re paying for — however you are paying a premium – Rest assured you are getting a premium battery though.
Pylontech Force H3X: Modular & Cost-Effective
Pylontech pricing is more modular and flexible. With the installation cost sitting around $9,000 to $11,500 for 20-30kWh of storage, depending on:
Number of battery modules
Inverter brand and size
Site-specific wiring or upgrade requirements
You can start smaller — eg. with 5.12kWh — and scale up later, spreading out your investment.
What About Rebates?
Both batteries are eligible for:
The federal battery rebate (from July 2025), worth a few thousand dollars depending on your system size
However, only the Tesla Powerwall 3 is eligible for:
The NSW VPP incentive, offering up to $1,500 upfront for joining a VPP program

20kWh single-phase system — from $9,990
30kWh single-phase system (two stacks) — from $13,950
35kWh three-phase system (one stack, 15kW inverter) — from $12,779
It’s worth noting that the three-phase setup is more cost-effective than its single-phase equivalent at this size, as it only requires one inverter and one stack. Beyond 35kWh, a second stack and inverter are needed, adding over $3,000 to the system cost.
You can also build a complete solar + battery package using Pylontech’s hybrid inverter.
For example:
These numbers make it clear: Pylontech delivers large-scale storage capacity and full system integration at a price point that’s highly accessible — especially for homeowners planning a long-term solar and storage setup.

You have booked in to get your battery installed and you’re wondering… Do you need to be home all day? Is it loud? How long does it take? And once it’s installed… then what?
We hear these questions all the time from homeowners. Adding a battery is one of the smartest moves you can make — especially with power prices rising and solar feed-in tariffs falling — but the installation day itself can feel like a bit of a mystery.
At Lenergy, we’ve installed batteries from brands like Sigenergy, Pylontech, ESY, and Anker Solix X1 in homes across NSW. We know what makes for a smooth install — and the common points where confusion creeps in.
In this guide, you’ll learn exactly what to expect on the day your battery gets installed. We’ll break it down step-by-step — including what happens during the install, what you need to do, when your system will go live, and how to avoid common surprises.
Most residential battery installations take half to one full day. If your setup is fairly standard — a single battery unit being added to an existing solar system — you can expect the team to arrive early (usually around 7:30 AM) and be done by mid-to-late afternoon.
That said, a few things can affect the timeline:
System size and complexity: Larger systems or multi-battery stacks (like a Sigenergy or ESY tower) may require extra time, especially if your home needs three-phase compatibility or additional cabling.
Indoor vs outdoor placement: Batteries installed indoors (in a garage or utility room) may take a little longer due to access or ventilation adjustments.
Pre-existing site conditions: If your existing solar inverter or switchboard needs upgrades, that can add hours or even an extra visit.
In most cases, your installer will confirm whether it’s a one-day or two-day job ahead of time — but rest assured, no one will leave you in the dark mid-install. The system won’t be left half-finished.
Do You Need to Be Home All Day?
You won’t need to shadow the installers all day — but someone does need to be home for most of it and here’s why:
Access to Key Areas
The battery installation involves work both inside and outside your home. Installers will need access to:
Your main switchboard
Any internal wall or garage where the battery is mounted
Possibly your roof cavity or manhole (especially if cabling needs to be run through internal spaces)
If you’re not home, the install may need to pause until access is available, which can cause delays.
Final Walkthrough
Toward the end of the day, your installer will walk you through:
How your system works
What to do in a blackout (if applicable)
How to monitor your usage and savings using the battery app
This part only takes 10–15 minutes, however it’s important. It’s your chance to ask questions and get comfortable using your new system from day one.
Will the Install Be Noisy or Disruptive?
Compared to other home improvements, a battery installation is relatively quiet — but you can expect some mild disruption during the day.
Here’s what you might notice:
Drilling and wall mounting Battery systems like the Anker Solix X1 or Pylontech often get wall-mounted in a garage, utility room or under eaves. Mounting the bracket and securing the battery will involve drilling into masonry or timber, which can generate short bursts of noise.
Switchboard work Some minor rewiring is needed to connect the battery to your main switchboard. This usually happens quietly, but there may be brief power interruptions while the system is safely integrated.
Installer movement If the battery is being installed indoors or cabling is routed through your ceiling space, you may hear light foot traffic or tools in use — especially if access is through a manhole or roof cavity.
No jackhammers or power saws If you’re picturing a full construction site — don’t. Most of the work is clean, controlled, and won’t disrupt your whole day.
If you’re working from home or have pets sensitive to noise, you’ll want to plan for occasional interruptions — but nothing too intrusive.
What Happens After the Battery Is Installed?
Once the physical installation is complete, the job’s not over — and that’s a good thing. Your installer will walk you through how to use your new system and make sure everything is working as expected before they leave.
System Testing and Commissioning
The installer will test your battery to confirm:
It’s correctly charging and discharging
The inverter recognises the battery and is communicating with it
Any blackout protection (if included) works as intended
If you’re installing a Sigenergy, ESY, or Anker Solix X1, this testing is often handled via a mobile app that also gives you remote access and performance data.
Monitoring App Setup
You’ll be guided through how to:
Use the app or web portal to track performance
Check your battery’s charge level, solar input, and usage stats
Know what’s happening during peak usage or blackout events
The app setup is important — this is how you’ll keep an eye on your system day-to-day. If the brand supports remote firmware updates (like Sigenergy or ESY), the installer may also run one before finishing up.
Final Handover
Before leaving, your installer should also:
Show you how to reboot the system if needed
Explain what to expect in the first few days
Provide contact details for support or questions
At this point, the system is physically ready — but it still needs to be integrated with your energy retailer before it goes live.
What Steps Involve Your Energy Retailer?
After your battery is installed and tested, the final step is to ensure your energy meter is compatible — especially if your system is new or older than six years. In these cases, it’s likely you won’t have a smart meter, which is essential for tracking energy flows between your solar, battery, and the grid.
Do You Need a Smart Meter?
Yes — smart meters are required for your battery system to work correctly with your energy retailer. They measure:
How much energy your battery stores and discharges
What you export to the grid
When you’re using power from the grid vs your battery
Without a smart meter, your battery’s performance — and any benefits like VPP participation or time-of-use optimisation — will be limited.
Who Organises This?
In most cases, this will be managed by your installer directly with your chosen retailer. At Lenergy, we take care of the entire process for you. We’ll submit the supply request, coordinate with your energy retailer, and make sure everything is ready for your battery to go live. You won’t need to fill out forms or make follow-up calls.
All you need to do is let us know which energy retailer you want to use — especially if you’re planning to trade your stored power through a Virtual Power Plant (VPP).
Once your smart meter is installed and your account is updated, your battery will be fully operational — charging, discharging, and reducing your reliance on the grid.
For a clear breakdown of benefits and how to apply, read our article below:
Once your battery is up and running, you might start thinking about what else it can do — and whether you can get even more value out of it.
Thinking About a VPP?
A Virtual Power Plant (VPP) is a program that links your battery to a network of other batteries. This allows your energy provider to draw stored energy from your system during peak times, often in exchange for payments, bill credits, or higher feed-in rates.
Some batteries, like the Sigenergy or ESY systems, are compatible with VPPs and offer app-based opt-in features. But be aware — VPPs aren’t for everyone.
Before joining one, make sure you understand:
How often your battery may be discharged
What compensation you’ll receive
Whether it limits your control or backup functions
Adding More Storage Later
If you’ve installed a modular battery system like Pylontech, Sigenergy, or ESY, you may be able to add more storage capacity down the line — without replacing your current setup.
This can be useful if:
Your energy usage increases (e.g. electric vehicle, larger family)
You want longer backup protection in case of outages
Your existing system doesn’t fully charge/discharge each day
If future flexibility is important to you, speak with your installer before making a final product choice — not all systems are equally easy to expand. To find out how to choose the right battery size, see our recent article below.
Have questions about your upcoming battery install or want to explore options like VPPs or future expansion? Get in touch with our team — we’re here to help you get the most out of your solar investment, from install day to every day after.
Pylontech isn’t the most well-known name in solar batteries — but that doesn’t mean it should be overlooked. Their Force H3X model is gaining traction as an affordable, stackable option for homes that want reliable backup and smart energy use without the premium price tag.
At Lenergy, we’ve recently added Pylontech to our battery offering. Here’s why — and what you should know before deciding if it’s the right fit for your home.
The Force H3X is Pylontech’s high-voltage battery designed for residential and small commercial solar storage. It’s a modular system — meaning each battery unit stacks vertically, letting you choose the capacity that suits your home now, and expand later if needed.
Each module stores 5.12kWh of usable energy. You can start with two modules for around 10.24kWh, or scale all the way up to 35.84kWh with seven — depending on your power use and future plans.
The Force H3X pairs with a hybrid inverter and is designed to handle both on-grid and off-grid scenarios. It supports three-phase backup, has a smart energy management system, and includes a clear visual display so you can check your battery status at a glance.
In short, it’s a flexible, all-in-one battery solution built for growing families, EV owners, and anyone looking to get more out of their solar — without going all-in on premium brands.
What Makes the Force H3X Different from Other Batteries?
While many solar batteries on the market offer similar core functions — energy storage, backup power, app monitoring — the Pylontech Force H3X stands out in a few practical ways:
Modular, Stackable Design
This battery is built with flexibility in mind. Each module stacks vertically in a clean tower format. That means no wall mounting, no messy wiring across shelves — just a tidy, floor-standing unit that’s easy to scale as your energy needs change.
Affordable Without Cutting Corners
Compared to higher-end brands, Pylontech offers solid value for money. It may not have the brand recognition of Tesla, but you’re still getting high-performance lithium iron phosphate (LFP) cells, decent efficiency, and robust safety features — at a lower price point.
Hybrid Integration
The H3X is part of a full hybrid system. The inverter, battery management system (BMS), and energy monitoring all work together, meaning fewer compatibility headaches and smoother performance — especially for blackout protection and time-of-use optimisation.
Visual Display
Unlike many other batteries that rely solely on an app, the Force H3X includes a built-in screen that shows live system status. It’s a small detail, but handy for homeowners who like to see what’s going on at a glance without opening their phone.
Three-Phase Backup Support
For homes with three-phase power, many batteries only back up one phase. The Force H3X supports full three-phase backup, which is critical if you want to keep large appliances or all circuits running during an outage.
Pros and Cons of the Pylontech Force H3X
Every battery has trade-offs. Here’s a balanced breakdown of where the Pylontech Force H3X performs well — and where it might fall short depending on your setup.
Pros
Modular and expandable Start with as little as 10kWh and scale up to over 35kWh as your needs grow. Ideal for families, EV owners, or anyone expecting to use more power in future.
Good value for money Offers strong performance and safety features at a more accessible price point than premium brands.
Visual status display Not all batteries include this — handy if you prefer checking your system without using an app.
Three-phase backup capable Unlike many batteries that only support single-phase backup, the Force H3X can support full three-phase homes.
High round-trip efficiency Rated peak efficiency up to 98%, meaning you lose less energy storing and retrieving power.
All-in-one hybrid setup Battery, inverter, and energy management are designed to work together — streamlining installation and performance.
Cons
Less brand recognition Not as well-known as Tesla or Enphase in Australia. May raise questions for buyers who value brand reputation or resale.
Requires floor space Because it stacks vertically, you need a dedicated floor area — which won’t suit every install location.
Relies on good system design Because the Force H3X is part of a hybrid system, performance depends on quality installation and inverter matching.
Limited app feedback in Australia Some users — especially in newer deployments — have raised questions about the app’s data depth and responsiveness. We’re monitoring how the software evolves as more homes adopt the system.
Who Is the Pylontech Force H3X a Good Fit For?
Not every battery suits every home. Here’s where the Force H3X tends to make the most sense.
Budget-conscious buyers who want reliability If you’re looking for a dependable battery but don’t want to stretch to premium prices, Pylontech offers strong value — especially for homes that use a lot of power after dark or during peak grid times.
Homes with three-phase power If your home has a three-phase setup, and you want full-house backup during outages (not just one circuit), the H3X supports this out of the box. That’s a big plus over many single-phase-only systems.
Households planning to grow Thinking of adding an EV? Installing more solar later? Anticipating a bigger power bill down the track? The H3X is modular — so you can start with two or three modules, and stack more as needed without replacing the system.
Homeowners who value visual feedback Not everyone wants to open an app every time they check their power usage. The built-in display gives you basic status info on the spot — a small feature, but one many homeowners appreciate.
Those wanting a hybrid all-in-one setup Because Pylontech offers an integrated inverter and battery setup, it can simplify design, installation, and service. That’s especially useful if you’re installing a full solar + battery system for the first time.
It may not be ideal if you’re focused purely on brand prestige, or if you have tight installation constraints where a wall-mounted battery is the only option. But for many homes, it offers a practical and future-proof balance between performance and price.
Final Thoughts: Is Pylontech Right for You in 2025?
If you’re looking for a solar battery that’s reliable, flexible, and more affordable than many of the big names — the Pylontech Force H3X is well worth considering.
It’s a solid fit for homes that want:
Full three-phase backup
Stackable storage that grows with your needs
A more affordable path to energy independence
Simplicity in installation and system management
It’s not about chasing brand recognition. It’s about getting a battery that fits your home, your usage, and your budget — without compromise where it counts.
If you’d like to find out if the Pylontech Force H3X is the right match for your home, get in touch with the team at Lenergy. We’ll walk you through your options — no pressure, just straight advice.
You’ve got solar panels on your roof and, on sunny days, they produce more power than your home can use. In most cases, that extra electricity is sent to the grid — and your energy retailer pays you a credit for it, called a feed-in tariff (FiT).
Sounds simple enough, However, there’s more to it than just “sell your power, get paid.” Your ability to export is shaped by network rules, meter settings, and even the cables running down your street. If you’re on a single-phase connection, you’ll often be limited to exporting a maximum of 5kW at any one time. Three-phase homes can sometimes export more — up to 5kW or even 10kW per phase — but this depends on your local network operator. In some areas with voltage rise issues, households have been set to zero export, meaning they’re not allowed to send anything back at all.
On top of that, FiT rates vary wildly between states and retailers, and new two-way pricing tariffs — like those from Ausgrid and Essential Energy — are changing how retailers value your exports throughout the day. Add in a few misleading headlines about “sun taxes” and it’s no wonder many people are unsure if exporting solar is even worth it anymore.
We’ve spent years helping Australian homeowners make sense of solar exports — from understanding feed-in tariffs and export limits to weighing up whether a battery or Virtual Power Plant (VPP) offers better value.
In this article, you’ll learn exactly how selling your extra solar power works in 2025, what you can realistically earn, and how to decide whether exporting, storing, or shifting your usage is the smartest move for your home.
What Is a Feed-in Tariff (FiT)?
A feed-in tariff (FiT) is the rate your energy retailer pays you for each kilowatt-hour (kWh) of electricity your solar system exports to the grid. It’s shown on your electricity bill as a credit, which is deducted from the amount you owe for the power you’ve imported from the grid.
Who sets the rate?
In most states, the government sets a benchmark or minimum rate, but your actual FiT is decided by your retailer. (eg AGL, Origin, Redenergy, Alinta Energy etc)
Some retailers offer higher rates to attract solar customers, while others stick close to the minimum.
Fixed vs time-varying FiTs
Fixed FiT: The same rate is paid for every kWh you export, no matter the time of day.
Time-varying FiT: Rates change depending on when you export. You might get a higher rate in the late afternoon or early evening when demand is high, and a lower rate during the middle of the day when the grid is flooded with solar.
Why FiTs are lower than the price you pay for power
You might pay 30–50c/kWh to buy electricity from the grid but only get 3–10c/kWh for what you export. That’s because FiTs are based on the wholesale value of electricity at the time of export — which is often low during sunny midday hours when solar supply is abundant.
2025 Feed-in Tariff Rates by State
Here’s how much solar households can expect to earn per kilowatt-hour (kWh) exported to the grid in 2025—but remember, actual rates vary depending on your state, postcode, and retailer.

Approx. FiT Range (2025)
Notes
NSW
4.8–7.3¢/kWh
IPART benchmarks for all-day flat rates. Retailers typically offer between 4–10c/kWh, depending on tiered daily thresholds.
What about two-way tariffs — a.k.a. the so-called “Sun Tax”?
From July 2025, Ausgrid and Endeavour Energy’s network in NSW introduced a new two-way pricing tariff. Some media outlets have labelled this a “Sun Tax”, however that description is misleading. It’s not a Government tax on households. Instead, it’s a pricing mechanism applied to electricity retailers, aimed at managing the grid more fairly and efficiently as solar uptake continues to grow.
Why it was introduced
Efficient use of the network — Grids were originally built for one-way power flow (from power stations to homes). With more rooftop solar than ever, the grid now has to handle energy flowing both ways. Two-way pricing encourages exports when the grid needs them, and discourages them when it doesn’t.
Fairer cost sharing — Previously, the costs of managing heavy daytime solar exports were spread across all electricity users — including those without solar. Two-way pricing allocates these costs more fairly to retailers, who may then adjust their solar plans.
Grid stability — Midday solar oversupply can overwhelm the network. By applying small charges for excess exports during those hours and offering rewards in the late afternoon/evening, Ausgrid reduces strain and helps avoid costly infrastructure upgrades.
Future readiness — With solar numbers still growing, two-way tariffs are designed to prepare the grid for even higher levels of rooftop solar in years to come.
How it works
Retailers are charged, not households directly. Ausgrid applies network export charges to retailers during the midday solar ‘glut’ and offers credits for evening exports.
Essential Energy in regional NSW has introduced its own two-way pricing as of 1 July 2025, allowing for both charges and rebates depending on timing and export volume.
Retailers decide how to pass this on. Some may slightly reduce FiTs; others might adjust daily supply or usage charges instead.
Free threshold. Most households can export a set daily amount without any impact. Only exports above this threshold, at low-value midday times, are affected.
Incentives for useful exports. Exports between roughly 4–9 pm may attract higher credits if your retailer passes these on.
For most households, the financial effect of two-way tariffs is modest—but they do highlight another reason why using solar energy yourself (rather than exporting it) can be more cost-effective.
What it means for you
In the short term, many customers won’t notice a big change, especially if their retailer keeps FiTs flat.
Over time, expect retailers to shift their solar plans: lower credits at midday, higher credits in the evening.
West-facing solar panels or a battery that can discharge during peak times are well placed to take advantage of these changes.
Why it matters
Two-way pricing reflects a broader shift in solar economics. The focus is moving from earning money through daytime exports to maximising self-consumption and evening exports. By using more of your own solar during the day, or storing it in a battery, you’ll save more on your bill and help keep the grid stable for everyone.
Can You Make a Profit from Selling Solar Power to the Grid?
For most Australian households, selling excess solar power to the grid is more about reducing your electricity bill than making a meaningful profit. The maths comes down to two key points:
You buy electricity for much more than you sell it
Typical purchase price from the grid: 30–50¢/kWh
Typical feed-in tariff in 2025: 3–10¢/kWh
That means every kWh you use yourself instead of exporting saves you up to five times more than selling it.
Export caps limit your earnings
In standard suburban single-phase homes, you can export up to 5 kW at any time.
Three-phase homes may be able to export more, but only if their network allows it.
In rural areas, stricter limits (or even zero-export rules) can further restrict your earning potential.
A real-world example
Let’s compare a household using 24 kWh/day versus exporting 24 kWh/day at different rates:
Scenario
Rate
Daily value
Quarterly value (90 days)
Buying from grid (best case)
30¢
$7.20
$648
Buying from grid (worst case)
50¢
$12.00
$1,080
Selling to grid (high FiT)
7¢
$1.68
$151.20
Selling to grid (low FiT)
3¢
$0.72
$64.80
Even at the higher end of FiTs, the credit you earn from exporting is modest compared to the savings you get from using that energy yourself.
When exporting can be more valuable
High time-of-use FiTs: If your retailer pays extra for late-afternoon or evening exports, you can time appliances to free up more solar for those windows.
Virtual Power Plants (VPPs): Some VPP programs pay higher rates or offer bonuses for allowing them to control your battery’s exports during peak demand.
When your solar panels produce more energy than you need, you have two main options:
Export it to the grid and receive a feed-in tariff (FiT).
Store it in a battery to use later, reducing the amount you buy from the grid.
The financial difference
Exporting to the grid: Typical FiT in 2025 is 3–10¢/kWh.
Using stored energy instead of buying from the grid: Saves you 30–50¢/kWh (your retail electricity price).
That means each kWh you store and use later is usually worth three to five times more than what you’d get selling it back to the grid.
Example: If you export 5 kWh/day at 7¢/kWh, you earn 35¢/day. If you store that same 5 kWh and avoid buying at 35¢/kWh, you save $1.75/day. Over a year, that’s $127.75 from exporting versus $638.75 from storing.
Now this is a small amount of export… Some houses are exporting 20+ KWH into the grid / day
See below example
When exporting might still be attractive
High time-of-use FiTs: Some retailers offer higher rates during peak grid demand. This could beneficial if you have a West Facing array of panels (west facing captures afternoon sun)
If you have a small system: You may not have much excess power to store, making a battery less beneficial.
Battery considerations
Upfront cost: A quality home battery typically costs $8,000–$15,000 installed.
Payback period: Often 7–12 years, depending on your usage patterns, electricity prices, and available rebates.
Flexibility: Batteries can also provide backup during blackouts and participate in Virtual Power Plant (VPP) programs for extra income.
How Virtual Power Plants (VPPs) Change the Equation
A Virtual Power Plant (VPP) links together many home solar and battery systems so they can be managed as one large power source. The VPP operator — often your electricity retailer or a specialist energy company — can control when your battery charges or discharges to help support the grid during high-demand periods.
In return, you receive payments, bill credits, or access to special electricity plans.
Sign-up bonuses or rebates: As it currently stands, the NSW VPP incentive offers $40-$55 / KwH to sign up. For example, 24kWH battery x $55 kwh = $1,320 as a VPP cashback
Better self-consumption: VPP software can optimise your battery usage so you use more of your own solar power.
Example
If a VPP discharges 5 kWh from your battery during a high-demand event and pays $0.50/kWh, you earn $2.50 for that event. Multiply that by dozens of events per year, and it can add hundreds of dollars to your annual return.
The trade-offs
Control: You give up some control over your battery. The VPP may discharge it when you’d prefer to keep it full.
Plan lock-in: You often need to stay with the same retailer for the VPP benefits.
Variable earnings: Payments depend on how often the VPP calls on your battery and the market price at the time.
Maximising the Value of Your Solar Exports
If you want to get the most out of every kilowatt-hour your solar system produces, you need to think beyond just the feed-in tariff (FiT) rate. A few smart changes can significantly improve the value you get from your solar investment.
Look for time-varying FiTs if your home can export during high-value periods (late afternoon/evening).
Read the fine print — some “high FiT” offers come with higher daily supply charges or less competitive usage rates.
2. Shift your energy use to daylight hours
Run appliances like dishwashers, washing machines, and pool pumps during the middle of the day when your panels are producing the most.
Use timers or smart plugs to automate this.
Every kWh you use yourself saves you 30–50¢ instead of earning you just 3–10¢.
3. Consider battery storage
Store excess energy to use during peak evening hours instead of exporting it.
Pair the battery with a Virtual Power Plant (VPP) to increase export value when the grid is under strain.
Take advantage of federal or state rebates to shorten the payback period.
4. Optimise your system for network rules
If you live in a rural area with lower export limits, focus on maximising self-consumption since you can’t send as much to the grid.
For homes with west-facing panels, align exports to late-afternoon demand peaks, which can attract higher FiTs.
5. Maintain your solar system
Dirty panels and underperforming inverters can reduce your output — and your export earnings.
Schedule regular inspections and cleanings, especially before summer.
Key Takeaways — Is Selling Your Extra Solar Power Worth It in 2025?
Selling your extra solar power back to the grid is still a useful way to reduce your electricity bill, but it’s rarely a big money-maker in 2025.
The pros:
Provides bill credits for unused solar power.
Easy to do once your system and smart meter are set up.
Can be combined with time-varying FiTs, or with a battery through VPP participation, for better returns
The cons:
Typical FiTs (3–10¢/kWh) are much lower than the price you pay for grid electricity (30–50¢/kWh).
Export limits and network constraints can reduce how much you can send to the grid.
Two-way pricing tariffs may lower FiT value in the middle of the day.
Who benefits most from selling to the grid?
Homes with no battery storage and consistent excess production. However, only marginally now.
West-facing systems that align with higher-value late-afternoon FiTs.
Battery owners participating in VPPs that pay premium export rates during peak demand.
The real financial win with solar is in self-consumption — using your own energy instead of buying from the grid. Selling to the grid is still worth doing for your unused solar, but it should be seen as a bonus, not the main source of value.
If you’re unsure whether exporting, storing, or joining a VPP is right for you, the team at Lenergy can help you assess your home’s usage patterns, network rules, and available rebates. Get in touch today to discuss the smartest way to use your solar so it works harder for your household.
Figuring out what size solar battery you need shouldn’t feel like learning a new language. Between “overnight usage,” “export limits,” and “peak sun hours,” it’s easy to feel like the more you read, the less you know.
And yet—battery size is one of the most important decisions you’ll make when going solar. Too small, and it’ll run out before your evening’s even over. Too big, and you might be paying for capacity you’ll never use. Plus, with the new federal rebate only claimable once, getting it wrong now could cost you later.
At Lenergy, we’ve helped thousands of homeowners size their solar and storage systems based on real-life usage—not guesses or generic recommendations. We know how to spot when a 10kWh battery makes sense, and when a 24 or 48kWh system would actually serve you better in the long run.
In this guide, you’ll learn exactly how to choose the right battery size for your home. We’ll walk through the formulas, examples, and trade-offs—so you can decide what fits your needs, your lifestyle, and your roof.
There’s no universal “right” battery size. The best fit depends on two things:
Whether you already have solar or not
How and when your household uses power
If You’re Starting Fresh: Solar + Battery
If you’re installing both panels and a battery, you can size the entire system around your needs. This means designing your solar array large enough to cover daily usage and charge the battery — especially in winter when generation drops and usage usually increases (this is the case in the Southern Highlands as it is colder and the AC heater is generally running more frequently. Though in warmer climates such as Newcastle, their energy use is quite stable and constant throughout the year)
It also means you can plan ahead. Thinking about buying an EV? Having Kids? Upgrading air con? Taking on housemates? Starting from scratch gives you flexibility to factor those changes into the design.
If You Already Have Solar: Battery Retrofit
Adding a battery to an existing system is a bit different. Here, the biggest question is: Do you have enough solar exports to fill a battery?
If you’re only exporting 2–3kWh a day, there’s not much spare energy to store. But if you’re exporting 10kWh or more, a battery starts to make a lot more sense.
What Size Solar System Do You Need to Charge a Battery?
If you’re installing solar for the first time, it’s not just about powering your home — it’s about generating enough energy to charge your battery too. This is where a simple sizing formula can help.
Step 1: Find Your Daily Energy Usage (usually on page 2 or 3 of your bill – see below snippet)
Your electricity bill will show your average daily usage, measured in kilowatt-hours (kWh). The above is 20kWh / day.
Let’s use another example and say it’s 24kWh/day — a common number for a family home.
Step 2: Estimate Your Local Sun Hours
Solar panels don’t generate their rated output all day long. In most parts of Australia, we use a conservative estimate of 3.6 peak sun hours (PSH) — the number of hours per day when solar panels operate at close to their rated capacity.
Step 3: Use the Sizing Formula
Solar system size (kW) = Daily usage (kWh) ÷ 3.6 (PSH)
For example:
24kWh ÷ 3.6 PSH = 6.6kW solar system
This means you’d need a 6.6kW system to roughly match your daily energy needs — assuming average weather across the year.
But remember: winter generation is lower, so it often makes sense to oversize slightly to ensure your system can still charge your battery during shorter, cloudier days.
If You Don’t Have Solar Yet: How to Estimate Your Battery Needs
If you haven’t installed solar yet, your electricity bill is your best clue — but it doesn’t tell the full story. It shows how much power you use each day, but not when you use it. That matters, because batteries only cover your night-time usage (when solar isn’t running).
So, how do you estimate battery size without solar data?
General Rule of Thumb
Most households use a good chunk of their energy at night — especially if everyone’s out during the day. Here’s how to estimate:
Light to moderate night-time usage: Battery size ≈ 50% of daily usage
Heavy night-time usage (away during the day): Battery size ≈ 75% of daily usage
So if this home adds solar + battery, either size could work — but we’d also want to check their lifestyle, winter usage, and future energy needs before finalising anything.
Keep in mind: If you size your battery before installing solar, you’ll want to make sure your panel system is big enough to charge the battery as well. That’s where the 6.6kW example from the last section fits in.
If You Already Have Solar: Can Your System Fill a Battery?
If you’ve already got panels on your roof, you don’t have to guess. Your electricity bill holds the answers — specifically in the solar export and daily usage numbers.
These tell you whether you’re generating enough excess solar to charge a battery and how much storage you actually need.
Step 1: What to Look for on Your Bill
Find these two figures:
Average daily usage (kWh) — your total electricity use
Average daily export (kWh) — how much solar you’re sending back to the grid
If you’re exporting less than 5kWh/day, there may not be enough spare energy to charge a battery — at least not consistently. If you’re exporting 10–15kWh/day or more, you’re in good shape to store that energy instead of selling it back for cents.
Example 2: Existing Solar, Moderate Use
From the bill shown below:
Key takeaways:
General usage = $0.29 / kWh
Daily supply charge = $1.30
Average daily usage = 13.75kWh
Average daily export = 11.7kWh
Controlled Load = 498kWh / 91 days = 5.5kWh per day
Given that this property already has solar, as indicated by the ‘solar exports’, we can gauge when they’re using power. If they are exporting power to the grid, this means they must be at least covering daytime usage with the excess going to the grid, which indicates that their usage must be occurring overnight.
Looking at the daily usage will indicate how much battery storage the homeowner needs, but we need to ensure there is enough excess energy to charge the batteries. Comparing daily usage (kWh) to daily export (kWh), we can determine whether there is sufficient excess power to charge a battery or if they need additional solar to cover a shortfall.
Calculation:
Average daily usage = 13.75kWh
Average daily export = 11.7kWh
This property consumes 13.75kWh per day, and in the same period exports 11.7kWh to the grid. Which indicates that this consumption must be occurring overnight. We can see that they are exporting slightly less than they are consuming, but this is negligible. To calculate the battery size we would take the lesser of the two values, in this case 11.7kWh is the amount of storage that would be required.
Example 3: You Use More Than You Export
Average daily usage: 30kWh
Average daily export: 10kWh
This home is using a lot more power than it’s sending back to the grid. With only 10kWh of excess solar on an average day, that’s all you have available to store in a battery.
Why This Limits Battery Size
A battery can only charge from surplus solar — unless you also charge from the grid. If you’re only exporting 10kWh a day:
A 10kWh battery will fill on a sunny day, but that’s it.
A 15–20kWh battery would rarely fill completely from solar, especially in winter. The extra capacity would sit underused.
That’s why, in many cases like this, we recommend adding more solar first before investing in a large battery — as explained in our blog Why Am I Still Getting an Electricity Bill?. More generation means more excess to store.
But What If You Can’t Add More Solar?
Sometimes adding panels just isn’t possible. You might be limited by roof space, shading, or a budget that can’t stretch to both solar and storage upgrades. In these cases, you have another option: force charging your battery from the grid.
How Force Charging Works
Some energy plans let you charge your battery from the grid during specific low-cost or free periods — then use that stored power when rates are higher. For example, OVO Energy’s “Free 3” plan gives you three hours of free electricity each day. If your battery can be charged in that window, you can fill it without relying solely on solar exports.
This approach can:
Reduce your peak-time grid purchases
Let you run a larger battery even with low solar exports
Take advantage of free or discounted energy periods
The Trade-Offs
You’re still dependent on the grid — so if it goes down, you won’t be able to force charge.
It works best if you’re disciplined about timing your charging to those free/cheap periods.
If your plan changes or incentives drop, the savings could reduce.
Key Takeaway
If you use more than you export, and adding solar isn’t an option, a time-based plan with force charging could be a viable way to make a battery work harder for you. But you’ll need to run the numbers to make sure it’s worth it — and choose a plan that suits your habits.
When Bigger Batteries Might Be Worth It
Not every home needs a large battery — but for some, going bigger offers real benefits beyond just storing solar. If you care about blackout protection, long-term flexibility, or joining a Virtual Power Plant (VPP), it might be worth sizing up.
Here are three reasons to consider it.
1. You Want Better Backup Power During Blackouts
Most batteries let you set a backup reserve — a percentage of stored energy that’s kept aside in case of a power outage. If your reserve is only 10%, a 10kWh battery leaves you with just 1kWh during an outage.
But with a larger battery, you can set a higher reserve without sacrificing too much usable storage.
Example: A 24kWh battery with a 40% reserve leaves you with 9.6kWh for outages — compared to just 2.4kWh on a 10% reserve.
If your area gets frequent blackouts, or you rely on medical devices, a bit of extra storage could be the difference between being covered and caught short.
2. You Want to Join a Virtual Power Plant (VPP)
Some energy retailers run Virtual Power Plant (VPP) programs, where you allow them to draw from your battery during peak demand. In return, you’re paid — often at rates well above standard feed-in tariffs — and in some cases you’ll also get a sign-up incentive.
This can be quite fruitful if you have surplus battery storage. When you’ve got plenty of energy left after covering your own needs, it usually doesn’t bother you if the retailer takes a small amount — especially when you’re being well compensated for it.
The risk comes when your battery is sized tightly to your usage. If the VPP draws power you were counting on for the evening, you might end up having to buy electricity back from the grid at peak rates — which can undo some of the financial benefits.
VPPs can be worth exploring if you regularly have excess stored energy, or if you’re sizing up your battery with participation in mind. For more on how these programs work, check out Amber’s SmartShift VPP.
3. Your Usage Might Increase Soon
Planning on:
Adding an EV charger?
Installing ducted air con?
Renting out a room?
If your household energy use is likely to grow, a slightly larger battery now might save you from having to expand later — especially with the rebate only claimable once (we’ll cover that next).
When Smaller Batteries Are a Smarter Fit
Not everyone needs the biggest battery on the block. In fact, for many homeowners, a smaller battery that’s well-matched to their usage offers better value — with fewer complications and a faster return on investment.
Here’s when it makes sense to keep things simple.
Your Usage Is Stable
If your household isn’t changing anytime soon — no EVs, no big appliances, no new tenants — a right-sized battery based on your current usage is usually enough. There’s no need to future-proof if your future looks the same.
You’re Not Interested in VPPs
If the idea of letting your retailer tap into your battery doesn’t appeal to you, you won’t need the extra headroom that larger systems offer for energy trading. Stick with a size that covers your needs and nothing more.
You Don’t Get Blackouts (Or Don’t Care About Backup)
If your area has a stable grid and you’re not fussed about keeping the lights on during the occasional outage, a small reserve — or none at all — is fine. No need to oversize for something that rarely happens.
You Want to Maximise Savings, Not Storage
Smaller batteries generally cost less and pay for themselves sooner — especially if you’re already exporting more solar than you use at night. In that case, even a 10kWh battery could make a noticeable dent in your bill.
But there’s one thing you need to keep in mind, no matter what size you’re considering — and that’s the rebate.
You Only Get the Rebate Once — So Size Carefully
Here’s something most people don’t realise until it’s too late: the federal battery rebate can only be claimed once.
That means if you install a 10kWh battery now, and later decide you should’ve gone with a 15kWh system — you’ll be paying full price for the upgrade. No second rebate. No top-up discount.
Why This Matters
It’s easy to underestimate your usage, especially if your needs grow over time. Maybe you:
Start working from home
Buy an EV
Install electric heating or cooling
Get hit with longer blackouts
If your battery can’t keep up, you’ll be stuck either buying from the grid (at peak prices) — or paying thousands to expand your storage without any incentive help.
The Safer Play
If you’ve got strong solar exports and you think your usage might increase, it may be smarter to size up slightly now — while the rebate still applies.
Final Checklist: How to Choose a Battery Size That Works for You
Still weighing up your options? Here’s a straightforward checklist to help you make sense of the numbers — and feel confident about your decision.
Do You Already Have Solar?
Yes: → Check your bill for both average daily usage and average daily export. → A healthy export number on its own doesn’t guarantee you can charge a battery — you need to compare it against your usage patterns. → Use the calculation we covered earlier: your battery size should not exceed your average daily export. If your export is less than the battery capacity you’re considering, it won’t fill consistently, especially in winter. → If exports are low compared to usage, adding more panels before storage will usually give you a better return.
No: → Start with your average daily usage from your bill. → Apply the 50–75% rule of thumb to estimate battery size, depending on how much of your usage happens at night. → Make sure your planned solar system is big enough to power your home and charge your battery, using the solar sizing formula from Section 2.
What’s Your Lifestyle Like?
Home during the day? → You might not need a big battery — your solar already covers daytime usage.
Out all day, home at night? → A larger battery may suit you better — more of your usage happens after sunset.
Do You Want Backup Power?
Frequent blackouts or medical needs? → Go bigger and set a higher reserve level. (look for something with full home back-up like Sigenergy)
Reliable grid and no outage concerns? → Smaller battery with minimal reserve may be fine.
Are You Joining a VPP?
Yes: → Consider oversizing slightly to avoid running short during energy sharing events.
No: → You can stick with a tighter match to your usage.
Are You Expecting Higher Usage in Future?
New appliances, EV, extra rooms or tenants? → Plan for it now — remember the rebate is one-time only.
Still Not Sure?
Start with your bill. Talk to your installer. And don’t feel pressured to go bigger just because. The right battery size is the one that matches your needs, fits your budget, and makes the most of the solar you already have — or plan to install.
What’s Happening to the Government Energy Rebates in December 2025?
Two key rebate changes are happening at the end of 2025:
1. The Federal Solar Rebate (STCs) is Decreasing on 1 January 2026 The solar rebate most Australians claim — based on Small-scale Technology Certificates (STCs) — drops in value every year until it phases out in 2030. The number of STCs you receive is tied to when your system is installed and signed off. Install after 31 December 2025, and you’ll receive fewer certificates for the exact same system.
The STCs are usually traded for a dollar value (currently around $35–$40 each), which comes off the upfront price of your system. Fewer certificates means a smaller discount.
2. A New Battery Rebate Is Starting Mid-2025 — But It Also Has a Timeline From July 2025, battery installations in Australia will also start generating STCs — meaning eligible battery systems will now attract a federal rebate, similar to solar panels. This is good news, but the rebate will also reduce every year (just like the solar scheme). The sooner you install, the more you can claim.
These changes mean December 2025 is a key cut-off point for locking in the highest available federal incentives — for both solar and battery systems.
If you install your solar system in January 2026 instead of December 2025, you’ll qualify for fewer STCs — and that means a smaller rebate.
Here’s a simplified example using a typical 6.6 kW solar system in Sydney:
Install Date
Estimated STCs
Rebate Value @ $37/STC
December 2025
92
$3,404
January 2026
84
$3,108
Difference: $296 less just by delaying a few weeks.
With a 10 kW system, the drop is even larger — closer to $450–$500 in lost rebate value.
And while the new battery rebate begins in July 2025, it will also follow a phasedown model. So, early adopters who install before the end of 2025 are likely to get the best possible return.
In short: Waiting until next year could cost you hundreds.
What You Need to Do Before the Deadline
To lock in the full 2025 rebate, your system doesn’t just need to be booked — it needs to be installed and signed off by 31 December 2025.
That sign-off comes in the form of a Certificate of Compliance (COC) or equivalent documentation, depending on your state. This confirms the system was physically completed and meets all safety and regulatory requirements.
Here’s what you should do:
Start your quote process now: The closer we get to December, the harder it is to secure installation dates.
Choose a Clean Energy Council–approved installer: Only accredited systems qualify for STCs.
Confirm your installer understands the rebate deadline: The rebate value is based on when your system is commissioned, not just when it’s ordered.
Allow for delays: Weather, supply issues, or grid approvals can push timelines out — aim to finish well before mid-December if possible.
And if you’re planning to install both solar and battery? It’s worth speaking to your installer about how to time the install so you maximise both rebates — especially if you’re eligible for the new battery STCs from July 2025 onward.
Is It Still Worth Installing Solar or Batteries After December?
Yes — but you’ll need to reset your expectations slightly.
Even after the rebate drops in January 2026, solar still delivers strong savings over time. A smaller rebate doesn’t erase the benefits of lower power bills, energy independence, and protection from rising electricity prices. It just means your payback period might be slightly longer.
The same applies to batteries. While the best value comes early in the new rebate cycle, batteries remain a solid long-term investment — especially if you:
Use a lot of power in the evening
Want blackout protection
Are planning to join a Virtual Power Plant (VPP)
Want to make the most of solar self-consumption
If you can’t install before the deadline, don’t panic. You’ll still access some rebate support — just less than if you had acted sooner. It’s still a worthwhile investment, especially if the system is sized right and tailored to your usage.
Common Questions About the Rebate Changes
Do I still qualify for the solar rebate in 2026? Yes, the federal solar rebate (STC scheme) continues until 2030. But the number of certificates you receive — and the rebate value — drops each year on 1 January.
What if my install is delayed past December? If your system isn’t installed and signed off by 31 December 2025, your rebate will be calculated based on the 2026 deeming period. It’s not a total loss — just a smaller benefit.
Can I combine the solar and battery rebates? Yes. If you install a battery from July 2025 onward, and it meets the eligibility criteria, you’ll get additional STCs for that battery on top of your solar rebate. The two rebates run under the same federal program but apply to different system components.
What if I only want a battery? From mid-2025, batteries installed on their own (with or without new solar) will qualify for STCs — so yes, you can claim a rebate on battery-only installs, provided the system meets the program requirements.
Will rebates keep decreasing every year? Yes. Unless the government changes policy, both the solar and battery STC rebates will step down annually until they phase out entirely in 2030.
If you’re planning to install solar or a battery system, timing matters.
The Federal solar rebate is already set to decrease from 1 January 2026 — and the new battery rebate launching mid-2025 will follow the same annual phase-down. By acting before December ends, you could save hundreds more than if you wait just a few weeks longer.
This doesn’t mean you should rush into the wrong system. But it does mean that if solar or battery storage is on your radar, now’s the time to ask the right questions, compare your options, and get the ball rolling before installation calendars fill up.
If you’re thinking about adding a battery to your solar setup, you’ve probably noticed there are a lot of options out there. Each one claims to be the smartest, most powerful, most reliable system on the market. It can be overwhelming trying to figure out which battery actually lives up to those claims—and which ones just sound good on paper.
We’ve recently had a lot of homeowners ask us about a newer battery called the ESY Sunhome HM6. It’s an all-in-one unit that combines a hybrid inverter with modular lithium battery storage. On the surface, it looks impressive. However: does it do what it says it does—and is it a good fit for your home?
In this review, we’ll break it all down. No hype. Just clear answers to the questions you’re already asking—about performance, reliability, blackout protection, pricing, and how it stacks up against other batteries in the same category.
The ESY Sunhome HM6 is a fully integrated solar battery system that combines two major components into one: a 6 kW hybrid inverter and modular lithium iron phosphate (LiFePO₄) battery storage. This means it can manage your solar input, store excess energy, and provide backup power—all in a single, compact unit.
One of the HM6’s biggest advantages is its modular design. Each battery module stores 5.12 kWh, and you can stack up to six modules, giving you a total capacity of 30.72 kWh. That kind of flexibility allows homeowners to start with a smaller setup and scale up as energy needs grow.
It’s also built for Australian conditions. The HM6 is IP66 rated—fully waterproof and dustproof—so it can be installed inside or outdoors without issue. It operates quietly (under 25 dB) and handles temperatures from –25 °C up to +60 °C, making it suitable for harsh environments.
The battery uses LiFePO₄ chemistry, which is known for being stable, long-lasting, and safe. It also includes intelligent features like real-time monitoring through a mobile app, as well as the ability to charge from solar even during a blackout, giving it a major edge in energy resilience.
In short, the ESY HM6 is:
A smart, all-in-one solar battery system
Scalable from 5.12 to 30.72 kWh
Built tough for real-world use
Quiet, low-maintenance, and easy to monitor
Designed to keep your home running—even during outages
Who Is This Battery Best Suited For?
The ESY Sunhome HM6 isn’t necessarily the right battery for every home—but for the right setup, it can be a solid option.
Ideal for Homes with Solar (or Planning to Add It)
If you already have solar or are thinking of installing it, the HM6 gives you a clear path to maximise your self-consumption. Instead of sending unused solar back to the grid for a low feed-in tariff, you can store that energy and use it later—especially in the evening when energy rates tend to spike.
Great for Households That Want Backup Power
If you live in an area prone to blackouts or just want peace of mind knowing your essentials will keep running when the grid goes down, the HM6 is worth considering. It can back up essential household circuits (like fridges, lights, Wi-Fi, and garage doors), additionally, it can recharge from your solar panels even during a blackout. Not all batteries can do that.
Perfect for Growing Energy Needs
The modular design makes it ideal for homeowners who want the option to expand. Maybe you’re starting with a smaller system now but plan to add an EV, pool pump, or extra living space later. With the HM6, you can scale from 5.12 kWh to over 30 kWh without needing to replace the whole setup. However, it is important to note; currently, you can only add the Federal Battery rebate once, so it is far more cost effective to do it once and do it right.
Who It Might Not Be Right For
Apartments or units with no dedicated solar access or installation space
Households that need whole home backup. This system only provides 6kW in the event of a blackout. If whole home backup is crucial then Sigenergy would be more suited.
Households that require a 3-phase backup solution (the HM6 is single-phase only—though it can still work in 3-phase homes for solar self-use) They are currently working on getting their larger 10kW systems approved for later in 2025.
Smart Features & Monitoring
These days, a good battery should do more than just store energy. It should help you understand how your home uses power—and give you the tools to stay in control. The ESY Sunhome HM6 delivers on that front with a full suite of smart features designed to make your energy setup feel less like guesswork and more like a well-oiled machine.
Real-Time Monitoring from Your Phone
With the HM6, you can track everything through a mobile app or online portal. You’ll be able to see:
How much solar your panels are generating
How much power your home is using
What’s going into (or coming out of) the battery
And what’s going to or from the grid
It gives you a live view of your system in action, 24/7. And if something isn’t performing the way it should, you’ll spot it straight away.
Installation & Warranty
Installation is straightforward for any CEC-accredited installer, and Lenergy has already integrated it into our standard install process. Because the inverter is built in, there’s less wiring, fewer components, and less room for things to go wrong.
And in terms of peace of mind? You’re backed by a 10-year warranty on both the inverter and battery, with at least 70% capacity guaranteed at year 10.
Pros and Cons
Every battery has its strengths and trade-offs, and the ESY HM6 is no different. But if you’re after something that’s simple, flexible, and well-built, it brings a lot to the table. Here’s a straight-up look at what it does well — and where it might not be the best fit.
Pros
All-in-one system – Battery + hybrid inverter in one sleek unit = easier install and less clutter
Modular and expandable – Start with one module (5.12 kWh) and scale up to 30.72 kWh
Recharges from solar during blackouts – A big plus for energy security during extended outages
LiFePO₄ battery chemistry – Safe, stable, and long-lasting
App monitoring & smart modes – Control and track your system in real-time
IP66 rated – Waterproof and dustproof, suitable for indoor or outdoor installs
Quiet operation – Passive cooling means no noisy fans
10-year warranty – Backed by solid performance guarantees
Cons
Single-phase only – Not ideal for homes needing 3-phase backup (though still compatible with 3-phase homes for general use)
Still relatively new in the Aussie market – Less brand recognition compared to Tesla or Sonnen
Stacked design adds height – A fully stacked 6-module system may need a bit more vertical clearance
Overall, the pros far outweigh the cons — especially if you’re looking for a reliable, scalable battery that doesn’t require multiple boxes and custom setups. But like any big energy investment, it’s important to match the system to your actual needs.
Final Verdict: Is It Worth It?
If you’re looking for a reliable, flexible, and well-priced battery to pair with your solar system, the ESY Sunhome HM6 is absolutely worth a look.
It offers a solid mix of features that matter in the real world — smart energy management, blackout protection, solar charging during outages, and the flexibility to scale over time. It’s built tough for Australian conditions, runs quietly, and doesn’t need a whole wall of hardware to get started.
No, it doesn’t have the brand name of a Tesla or the price tag of Sigenergy — but that’s exactly why it stands out. It strikes a great balance between quality, simplicity, and value. At Lenergy, we proudly supply and install the ESY HM6 as part of our residential battery offering. If you’ve got questions or want help deciding if it’s the right fit for your home, our team is always happy to chat.
Ever wondered what it’s like to live without relying on the grid?
Maybe your property’s too remote to connect easily, or maybe you’re just tired of rising electricity prices and want more control. Off-grid solar sounds appealing. No power bills, no outages, full independence. But is it really that simple?
At Lenergy, we’ve helped many homeowners explore off-grid living. Some go all-in. Others realise it’s not quite the right fit.
In this blog, you’ll understand the key benefits of off-grid solar systems, the downsides, and how to know if off-grid solar is right for you.
An off-grid solar system is a solar setup that runs completely independent of the electricity grid. It generates, stores, and supplies all the power your home needs, without any backup from the main grid.
That energy is sent to a solar inverter, which converts it into usable electricity.
Excess power is stored insolar batteries for use at night or during cloudy days.
A backup generator is often included as a safety net for extended periods of bad weather or high usage.
Unlike grid-connected systems, you can’t fall back on the electricity network. That means your system needs to be sized correctly for your home’s usage and your lifestyle, so you don’t run out of power when you need it most.
Off-grid systems are common in rural or remote areas where connecting to the grid would be difficult or costly. But they’re also becoming more popular with people who want energy independence, even if the grid is technically available.
Why Go Off-Grid? The Main Benefits
So why do people choose to cut the chord from the grid entirely? It usually comes down to four key reasons:
1. Total Energy Independence
Living off-grid means complete energy autonomy. You’re no longer dependent on power companies, vulnerable to network failures, or exposed to fluctuating electricity rates. By generating and storing your own power, you gain full control over your energy supply—eliminating ongoing connection fees, unexpected price hikes, and the inconvenience of blackouts during storms or maintenance disruptions. This level of independence not only enhances reliability but also offers peace of mind, especially in areas where grid infrastructure is aging or inconsistent.
2. Perfect for Remote Properties
For homeowners living in rural or regional areas, connecting to the electricity grid can be logistically difficult and prohibitively expensive—often costing tens of thousands of dollars just to extend power lines to a property that’s far from existing infrastructure. These costs don’t even include ongoing network service charges or rising electricity rates.
In contrast, off-grid solar systems offer a self-contained energy solution, enabling complete energy independence without reliance on the grid. When designed correctly, these systems can meet the needs of modern households just as reliably, with the added benefit of avoiding grid outages and infrastructure delays. For many remote properties, going off-grid isn’t just an environmentally conscious decision—it’s a financially and practically smarter alternative in the long term.
3. Lower Long-Term Energy Costs
Although the initial cost of installing an off-grid solar system can be significant, it eliminates ongoing electricity bills entirely. Over the years, this can lead to substantial savings—particularly as traditional energy prices continue to rise. Many homeowners find that the money they would have spent on grid power eventually equals or exceeds the cost of their off-grid system, making it a financially smart long-term investment.
4. Sustainable Living
Off-grid solar systems draw energy from the sun (a clean, renewable resource). Allowing homeowners to power their homes without relying on fossil fuels or contributing to greenhouse gas emissions. For those committed to environmental responsibility, this approach significantly reduces your carbon footprint while promoting energy independence. It’s an ideal solution for individuals seeking a more sustainable, self-sufficient lifestyle that aligns with eco-conscious values.
The Drawbacks You Need to Know
Going off-grid has its perks, however it’s not for everyone. Here are the main trade-offs to be aware of:
1. Higher Upfront Costs
Off-grid solar systems generally involve a higher initial cost compared to grid-connected setups. This is largely due to the additional infrastructure required—such as larger battery banks, advanced inverters, and often a backup generator—to ensure consistent energy supply around the clock. In essence, you’re creating a fully independent power system capable of meeting all your energy needs without any external support. While this level of self-sufficiency demands a greater upfront investment, many homeowners see it as a worthwhile trade-off for long-term energy freedom and protection against rising grid costs.
2. You’re 100% Responsible for Your Power
Living off-grid means full energy independence—but with that freedom comes complete responsibility. If your system is undersized, poorly designed, or if your household consumes more energy than expected, you risk depleting your battery reserves—especially during winter months or extended periods of cloud cover. Without the safety net of the grid, even a few miscalculations can result in inconvenient (or even dangerous) power shortages. That’s why investing in a professionally designed system, accurate load assessments, and proper energy management habits is essential. Many homeowners also choose to include a backup generator as a safeguard for these unpredictable conditions.
3. Battery Maintenance and Replacement
Batteries are a critical component of any off-grid solar system, responsible for storing the energy needed to power your home day and night. However, they come with a limited lifespan. Depending on the battery chemistry—whether lithium-ion, lead-acid, or newer technologies—you can expect a replacement from anywhere between 5 to 15 years. While modern lithium batteries often require little to no maintenance, some systems (especially lead-acid) may demand regular checks on fluid levels, charge cycles, and temperature conditions.
Over time, these replacement and upkeep costs can add up, making it important to factor them into your long-term energy budget. Choosing a high-quality battery with a strong warranty and planning for its eventual replacement ensures your off-grid lifestyle remains reliable and stress-free.
4. Not Ideal for High Energy Users
Off-grid solar systems are best suited to energy-conscious households with predictable and moderate electricity needs. If you have a large family, run a home business, or use multiple high-draw appliances—such as ducted air conditioning, pool pumps, electric ovens, or EV chargers—designing a system to meet those demands can be complex and costly. You’ll need a significantly larger solar array, increased battery storage, and potentially a backup generator to ensure consistent power supply year-round.
In many cases, high energy users may need to rethink their habits or upgrade appliances to more efficient models to make off-grid living feasible. That might mean switching to gas cooking, scheduling appliance use during peak sunlight hours, or staggering high-consumption devices to avoid overload. While not impossible, it does require a lifestyle shift and a deeper investment in system infrastructure to ensure comfort and reliability without access to the grid.
Is Off-Grid Right for You?
Off-grid solar isn’t a one-size-fits-all solution. Here’s a quick checklist to help you decide if it fits your lifestyle and goals:
It might be right for you if:
You live in a remote or rural area where grid connection is costly or unreliable.
You value energy independence and don’t want to rely on power companies.
You’re happy to adjust your energy use to suit what your system can provide.
You’re willing to invest upfront for long-term savings and security.
You’re committed to a low-impact, sustainable lifestyle.
It might not be right if:
You’re in a metro area with easy, stable grid access.
Your household uses lots of power, especially during evening hours.
You’re looking for the cheapest option right now rather than long-term value.
If you’re not ready to fully disconnect from the grid, a hybrid solar system offers a balanced alternative. By combining solar panels, battery storage, and a grid connection, hybrid systems provide flexibility—allowing you to store excess solar energy for use during peak times or outages, while still drawing from the grid when necessary. This setup can lead to lower electricity bills, increased energy reliability, and greater independence from utility price fluctuations.
Choosing the Right System for Peace of Mind
Going off-grid isn’t just a trendy move or a tech-savvy experiment—it’s a strategic decision rooted in your lifestyle, location, and long-term goals. For homeowners in remote areas or those seeking complete energy independence, a well-designed off-grid system can provide long-term reliability, energy savings, and peace of mind.
However, it’s equally valid if off-grid living isn’t the right fit for you. A hybrid solar system—combining solar, battery storage, and grid connection—may offer a more balanced solution, delivering energy savings and greater reliability without sacrificing flexibility.
What matters most is that you’re informed. Understanding the benefits, challenges, and realistic expectations of each option allows you to make the right decision with confidence.
Before making any commitments, it’s essential to speak with a reputable solar installation company—one that listens to your needs, provides transparent advice, and customizes a solution that works for you. At Lenergy, we’re here to help guide you through that process, whether you’re ready to go fully off-grid or exploring hybrid options tailored to your property and lifestyle.
