Still got questions? That’s what we’re here for. Reach out, ask away, and let’s see if Sigenergy is right for your home.
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.
If you’ve been considering a home battery in NSW, you’ve likely come across news about the state’s battery rebate program—and now, the unexpected update that it’s coming to an end.
For months, both Penny Sharpe (NSW Energy Minister) and Chris Bowen (Federal Energy Minister) publicly stated they were working to overcome the issue of “incentive stacking”—the challenge of offering state and federal rebates on the same battery install. They encouraged people to carry on as normal, suggesting a collaborative solution was in the works.
So it’s come as a surprise to many that NSW has now confirmed its battery rebate will end on 1 July, right when the new federal program is expected to begin.
There’s still support coming from the Commonwealth—potentially covering up to 30% of the battery cost—but the change of direction at state level has caught many off guard. Especially for homeowners who made plans under the assumption that both incentives could be used together.
What Will Replace the NSW Battery Rebate?
Rather than continue offering a rebate, the NSW Government will instead boost Virtual Power Plant (VPP) incentives under the Peak Demand Reduction Scheme (PDRS).
If you install a battery and sign up to a VPP with an eligible provider, you could receive up to $1,500, depending on the system size and provider offer—an increase from the average $800 currently available.
However, this is not the same as a direct, upfront rebate. To access the VPP incentive, you must:
Sign up for a minimum three-year VPP contract
Agree to let your battery be accessed by the provider during certain times (typically peak demand)
For some homeowners, that’s no issue. For others, particularly those who want to maintain full control over how and when their battery is used, the idea of being locked into a contract—and potentially seeing their stored energy discharged when they need it most—raises concerns.
So while stacking the state’s VPP incentive with the federal battery rebate is possible, it’s not quite the solution many were expecting.
Is It Still Worth Getting a Battery?
Yes, it still is. While the NSW battery rebate is coming to an end, the federal rebate is substantial—covering around 30% of battery system costs, which adds up quickly, especially for larger installations.
This new rebate alone makes battery storage far more accessible than before—and that’s before you even consider additional incentives like VPP payments under NSW’s PDRS scheme.
How Much Can You Save with the 2025 Battery Rebates?
Here is a clear look at potential savings using Sigenergy’s SigenStor modular batteries:
Number of Units (kWh)
Federal Rebate
1 (8kWh)
$2,792
2 (16kWh)
$5,585
3 (24kWh)
$8,378
4 (32kWh)
$11,171
5 (40kWh)
$13,963
6 (48kWh)
$16,756
These figures demonstrate how substantial the rebate really is. Even without a state rebate or VPP participation, these discounts significantly lower the upfront cost.
However, it’s worth noting that VPP incentives, while still available, require a minimum 3-year commitment and some level of operational control over your battery. That’s not something everyone is comfortable with, especially if you prefer full control of your stored energy or the flexibility to change plans later.
So, if you’re considering a battery—and would rather avoid long contracts—a system like Sigenergy’s, combined with the federal rebate alone, could still offer great value without compromise.
Final Thoughts
This rebate change has come sooner—and more definitively—than many expected, especially after repeated reassurances from both state and federal ministers.
It’s disappointing for those who planned to make the most of both incentive streams. And while support hasn’t disappeared entirely, it now comes with more conditions and longer commitments than what was originally promised.
At Lenergy, our goal is to keep homeowners informed—not pressured. If you’d like to stay updated on how these policy changes evolve, or want help understanding what your options look like under the new structure, feel free to get in touch at lenergy.com.au/contact.
We’ll continue to share transparent, up-to-date information to help you make the best decision for your home.
Do you know that running your dishwasher at 7 pm costs more than doing it at 10 pm?
It’s the same appliance, same power usage, so why the price difference?
Most people don’t realise that electricity isn’t priced equally all day. Depending on when you use it, the cost can jump significantly, especially if you’re on a time-of-use tariff.
The problem? Many Australians are unknowingly using the bulk of their power during peak periods, when demand is highest and rates are too. That quiet spike in cost can make your bill feel confusing or even unfair.
At Lenergy, we get how frustrating it is to feel punished for just living your routine. That’s why we’re here to clear it all up, so you can make an informed choice.
In this guide, you’ll learn what “peak electricity times” really mean, why they exist, and how to make simple shifts that could save you money every single month.
If you’ve ever looked closely at your energy bill or even just heard the term “peak pricing,” you might be wondering what it actually refers to.
In simple terms, “peak electricity times” are the hours of the day when most people use power at the same time. Think of it like rush hour on the roads: everyone’s cooking dinner, doing laundry, running the heater or air conditioner, and charging devices all at once. With more demand on the grid, the price of supplying electricity goes up, and so does the rate you’re charged.
Here’s how energy use is typically broken down across a day:
Peak: These are the busiest, most expensive hours. In the late afternoon and evening (such as 4 pm to 9 pm), when people get home from work.
Off-Peak: These are the quiet hours, overnight (between 10 pm to 7 am), when far fewer people are using electricity, and rates are lower.
Shoulder: These are the in-between periods, like mid-morning or early afternoon, where demand is moderate and prices sit somewhere in the middle.
Understanding this time-based pricing is the first step in learning how to better manage your energy costs and your usage habits.
Why Does Electricity Cost More at Certain Times?
The answer lies in demand and supply. During peak periods, when lots of households and businesses are using electricity at the same time, energy providers have to generate and distribute more power quickly. This often means turning to more expensive or less efficient sources of electricity to keep up.
Think of it like this: if everyone turns on their air conditioner at 6 pm on a summer evening, the grid gets overloaded. To meet that sudden spike in demand, providers may need to bring in backup power, which costs more to supply. Those extra costs get passed on to you in the form of higher rates during peak times.
It’s also about managing the load on the network. If the system gets too overloaded, it risks outages or instability. Higher pricing during peak times helps spread out demand, encouraging some people to shift their usage to quieter periods.
In short:You’re not just paying for the electricity itself. You’re also paying for how easy (or hard) it is to deliver it to you at that specific time.
When Are Peak Electricity Times in Australia?
The answer can vary depending on your state, your electricity provider, and your specific plan. However, most follow a similar pattern based on overall demand trends.
Note: Time blocks and definitions vary slightly between energy retailers. Weekends and public holidays may have reduced rates or default to off-peak/shoulder times. Always refer to your individual plan for exact times.
Knowing these time windows helps you make smarter decisions about when to run major appliances or use power-hungry devices.
How Do Time-of-Use Tariffs Work on Your Electricity Bill?
With a time-of-use tariff, your electricity usage is charged at different rates depending on the time of day you use it. Instead of paying a flat rate per kilowatt hour (kWh), your bill reflects how much energy you used during peak, shoulder, and off-peak periods.
Here’s a basic example:
Time Period
Usage
Rate per kWh
Total Cost
Peak (4–9 pm)
3 kWh
40 cents
$1.20
Shoulder (9 am–4 pm)
5 kWh
25 cents
$1.25
Off-Peak (10 pm–7 am)
7 kWh
15 cents
$1.05
Total
15 kWh
$3.50
If you had used all 15 kWh during off-peak hours, your cost would have been $2.25 instead of $3.50. That’s a 36% difference, just based on timing.
Your bill typically includes:
A breakdown of usage by time period
A rate for each period
A fixed daily supply charge (regardless of usage)
With a Time-of-Use (TOU) plan, it’s not just how much energy you use, but when you use it that affects your final cost. That’s why shifting usage to cheaper periods can make a real difference over time.
5 Simple Ways to Save Money by Avoiding Peak Times
Now that you know what peak electricity times are and how they affect your bill, the next step is making small changes that can lead to real savings.
Here are five practical, beginner-friendly strategies:
1. Use timers on major appliances
Many dishwashers, washing machines, and dryers have a delayed start feature. Set them to run after 10 pm when off-peak rates usually kick in. You’ll get the exact same cleaning for less money.
2. Charge devices and electric vehicles overnight
If you charge phones, laptops, or an electric vehicle at night, do it during off-peak hours. Plug in before bed and wake up to full batteries at lower costs.
3. Shift heating and cooling use
Heating and cooling are some of the biggest energy consumers. Instead of blasting the heater at 7 pm, preheat your space slightly earlier during shoulder times and use insulation or closed doors to maintain comfort.
4. Avoid running everything at once in the evening
This one’s simple: don’t cook, run the dryer, charge devices, and take a hot shower all between 6 and 8 pm. Spread out your usage to avoid the costliest window.
5. Use a smart energy monitor
If your home has a smart meter, some energy providers offer apps or portals that show your real-time usage. This helps you spot patterns and identify what’s costing you most during peak times.
These changes might feel small, but they add up. If you regularly move just 20 to 30 per cent of your energy use to off-peak times, you could see a noticeable drop in your bill, without giving up any comfort or convenience.
Should You Even Care About Peak Times?
If you’re one of the richest men in Australia, you really shouldn’t care about peak times. You can pay whatever so why bother? But if you’ve made it this far in this article, we’re guessing you’re not one of the richest men in Australia, so you should definitely care.
It’s not about obsessing over every appliance or sitting in the dark to save money. It’s about knowing how your bill works so you can make a few smarter choices. Once you understand how peak times impact your costs, you’re no longer stuck with a “surprise” at the end of each billing cycle.
Caring about peak electricity times isn’t about adding stress. It’s about gaining clarity, reducing waste, and making your energy spend work better for you.
You’re probably wondering, “Can I actually get solar installed without paying anything upfront?”
It’s a question we hear all the time—especially when we’re out speaking with homeowners face-to-face. It’s easy to see why people are sceptical—getting solar with no upfront cost sounds too good to be true.
At Lenergy, we want to help you make an informed decision when it comes to anything solar. In this guide, you’ll get a clear, honest look at how you can get solar installed with no upfront payment, and what options you actually have.
By the end of this article, you’ll know exactly how our different finance and plan options work.
Option 1: 0% Interest Loan – Own Your System, No Upfront Costs
Want to own your solar or battery system but don’t want to fork out the full cost upfront? Lenergy’s 0% Interest Loan could be the perfect fit. This option allows you to install a brand-new solar or battery system with no deposit required and you’re able to pay it off over five years—interest-free.
Here’s how it works:
$0 Upfront – No deposit or initial payment needed to get started.
0% Interest for 60 Months – Spread your repayments over five years with no added interest or hidden fees.
Start Saving from Day One – Your energy savings can help offset your loan repayments.
You Own the System – From day one, you’re investing in your property—not renting a system.
Example: If your electricity bill is around $250 a month, switching to solar could reduce it dramatically—sometimes even down to zero. Instead of handing that money to your energy retailer, you can redirect it toward your loan repayments. You’re essentially swapping your power bill for a solar repayment—with the added benefit of owning your system outright at the end.

Following the 6 April 2025 announcement by the Australian Government and Labor’s re-election on Saturday 4 May, there has been significant interest and some public debate around whether the new Federal “Cheaper Home Batteries Program” can be stacked with existing state-based incentives, such as the NSW Peak Demand Reduction Scheme (PDRS).
In 2025, the Federal battery rebate will offer a maximum of $372 per kilowatt-hour (kWh) of usable battery capacity. After accounting for administrative fees, the real-world discount is expected to be closer to $330 per kWh.
Like the solar panel rebate, this subsidy is designed to gradually reduce each year until it phases out at the end of 2030.
To give you an idea:
After fees, that translates to an approximate $3,300 reduction in upfront installation costs.
A 10 kWh battery would be eligible for up to $3,720 in rebate value.

While the Federal Government has stated its intention for this rebate to work alongside state-based schemes, there are still some regulatory hurdles being addressed — especially in NSW. These complexities are being worked through, and updates are expected before the program launches on July 1, 2025.
Can You Combine It with the NSW Battery Rebate (PDRS)?
As it currently stands, no — this is one of the biggest misconceptions right now.
When the Federal battery rebate was first announced, there were no finalised program guidelines. At the time, many reputable sources interpreted the public information to suggest the new rebate might be compatible with existing state schemes.
The Australian Federal Government along with the NSW State Government has expressed a clear intent for its Cheaper Home Batteries Program to be stackable with existing state-based incentives, such as New South Wales’ Peak Demand Reduction Scheme (PDRS).
An instagram post from Australian Energy Minister Chris Bowen includes a video where he confirms the Federal Government’s intention for its new battery rebate to work in conjunction with existing state incentives. You can view the clip here: Instagram – Chris Bowen Statement
The Sydney Morning Herald published an article on April 5 stating that the Federal Government would provide up to $4,000 per household as part of its plan to subsidise battery storage in addition, “Labor’s scheme could be combined with assistance on offer from state governments”.
NSW Energy Minister Penny Sharpe confirmed in a recent Energy Insiders podcast when asked: “How does your scheme (NSW PDRS) dovetail with the federal scheme?
“Look, we want them to work together. There’s some issues that, look, there’s always these challenges in terms of working, you know, how do you integrate them? How do you make them work together? I’m sure we’ll be able to work through that……. So, yeah we’ll work with the federal government. I’ve talked to Chris about how we can make sure that those things work together.”
Around the same time, Federal Climate and Energy Minister Chris Bowen gave public statements suggesting the rebate would operate similarly to the Small-scale Technology Certificates (STCs), which often can be used alongside state programs:
Federal Policy Intention: Yes, Stacking Is Planned
The Federal and State Government has been clear in the intended design: the new rebate should work in conjunction with existing state subsidies. Minister for Climate Change and Energy Chris Bowen has publicly reiterated this, even appearing alongside a NSW installer to promote how the federal rebate complements the NSW scheme.
Current Technical Hurdle: NSW Scheme Needs an Update
Despite the shared intent, the technical rules in the current PDRS framework mean that, as it stands, battery installations eligible for the federal rebate may not simultaneously qualify under NSW’s current rules. Specifically, PDRS Amendment No.3 Section 5.4(e) excludes any system that qualifies under the Renewable Energy (Electricity) Act 2000 — the act through which the federal rebate is being administered.
This has created a temporary limitation, but one that both governments have publicly committed to resolving.
Resolution Underway
According to recent reports, including SolarQuotes’ interview with NSW Government officials, regulators are actively reviewing the policy to remove these barriers. The goal is to enable eligible homeowners and small businesses to claim both rebates as originally promised.
We confirmed this with the NSW Government Department of Climate Change, Energy, the Environment and Water, who have stated that they are working closely with the Commonwealth Department responsible for battery policy development to work through the interactions between the NSW and Federal schemes.
Lenergy’s Position
Lenergy supports the combined intent of both programs and is continuing to:
Monitor official updates from federal and state regulators
Advise clients based on the best available government guidance
Schedule eligible battery installations from 1 July 2025 onward, when the federal rebate begins
Ensure all systems meet requirements for VPP-readiness, capacity, and installation compliance
At Lenergy, we’ve aligned our approach with this direction — and that’s why we’re helping customers prepare now to take full advantage of both State and Federal Rebates on solar battery systems from July 2025 onwards.
Long story short. No you can’t combine them as it currently stands. But they have publicly stated that they are working to change this.
We have been informed that we will have answers prior to the 1st of July. As updates unfold, we’ll keep this page current — and continue to provide transparent guidance to help Australians make smart energy decisions.

Why is your electricity bill still going up when you feel like you’re doing everything right?
You switch off the lights when unused. You don’t run the heater all day. You’re not using any new appliances. And yet, month after month, the bill keeps climbing.
At Lenergy, we hear this from different households all the time. The truth is, it’s not always the big things that drive your energy costs. Often, it’s the small, everyday habits that quietly add up. Unless you know where to look, they’re easy to miss.
In this blog, you’ll learn exactly what’s really affecting your electricity bill, and how simple behaviour changes at home can lead to real, noticeable savings.
Let’s break down the key things that can really drive up your electricity costs.
1. Appliance Usage
Not all appliances are created equal. Running a dishwasher once a day doesn’t use the same energy as running a reverse-cycle air conditioner for hours. Big-ticket appliances like heaters, air conditioners, dryers, ovens, and fridges are responsible for a large share of your energy use, and how you use them matters just as much as how often.
What makes it worse:
Running high-energy appliances during peak times
Using inefficient or older models
Forgetting to maintain or clean filters and vents
2. Heating and Cooling Habits
Climate control is a major cost in most Australian homes, especially in extreme seasons. A heater or air conditioner running all day, even at just a couple of degrees too high or too low, can significantly spike your bill.
What makes it worse:
Leaving systems running when you’re not home
Setting the temperature too low in summer or too high in winter
Failing to insulate or seal doors and windows properly
3. Standby Power
Even when devices are off, they’re often not really off. TVs, game consoles, modems, microwaves, and even coffee machines often draw power in standby mode (sometimes 24/7).
What makes it worse:
Leaving devices plugged in and switched on at the wall
Not using switched power boards.
Having multiple entertainment or office setups running simultaneously
4. Daily Routines and Timing
Running appliances during peak times (like early evening) can cost more if you’re on a time-of-use tariff. Even if your rate is flat, using lots of power during peak grid demand can impact supply and future pricing.
What makes it worse:
Doing laundry, dishes, or showers during peak hours (7am-9am and 5pm-8pm)
Boiling the kettle multiple times a day
Letting the dryer or oven run longer than needed
5. Lighting and Electronics
While lighting may not be your biggest energy user, it still matters, especially if you’ve got a large home or you’re using older globes. The same goes for computers, gaming systems, and home office gear.
The most overlooked factor? Human habits. Two identical homes with the same appliances can have completely different bills based on how people live in them.
What makes it worse:
Being unaware of how much energy certain behaviours use
Not tracking or checking usage
Assuming small things don’t matter
Your electricity bill isn’t just about what’s plugged in. It’s about how and when you use it. The key is awareness. Once you know where the power goes, you’re in a better position to manage it, without giving up comfort.
The Real Cost of Habits
You might not realise it, but it’s often the little, automatic things you do every day that quietly drive up your electricity bill. These habits feel harmless, until they become routine. Let’s break down a few examples.
Leaving Devices on Standby
That red light on your TV? It’s a tiny cost on its own. But now multiply that across your modem, game consoles, soundbar, microwave, coffee machine, and chargers left in the wall. Suddenly, standby power can account for 5–10% of your total energy bill. It’s called “vampire energy” for a reason. It drains power even when nothing’s being used.
What you can do: Use a power board with a switch, and turn it off overnight or when you leave the house. Easy win.
Heating and Cooling Without Thinking
Australia’s climate swings, from scorching summers to chilly winters, can tempt anyone to overuse air conditioning or heating. But setting your thermostat just 1°C higher in summer or lower in winter can increase your energy use by around 10%. (link blog to ideal temp)
What you can do: Before turning on energy-intensive appliances like air conditioners or heaters, consider more energy-efficient alternatives. In summer, ceiling fans can significantly reduce the need for cooling by improving air circulation, and they use far less electricity than traditional air conditioners. During winter, layering your clothing and using blankets can help maintain warmth without immediately resorting to heating systems. Also, be mindful of your home’s insulation—closing doors and windows ensures that the conditioned air stays inside, rather than escaping outdoors.
Running Appliances at the Wrong Time
In many regions across Australia, electricity providers offer time-of-use pricing, where the cost of power varies depending on the time of day. Off-peak hours—usually late at night or early in the morning—come with significantly lower rates. By contrast, using high-energy appliances such as dishwashers, washing machines, and clothes dryers during peak periods (typically weekday evenings) can result in unnecessarily high electricity bills.
What you can do: Use timers or delay-start functions to run major appliances including dishwashers, washing machines, and clothes dryers overnight. It’s better for your bill and the grid.
Using the Wrong Settings
Washing clothes in hot water or overloading your fridge might not seem like a big deal, but it adds up. Washing with cold water can cut your machine’s energy use by up to 80%, and keeping your fridge overpacked reduces airflow, making it work harder.
What you can do: Wash clothes in cold water. Keep fridge temps at 3–5°C and don’t block the vents inside.
Lights, Everywhere
Leaving lights on is one of the oldest habits in the book. Even with energy-efficient LEDs, it’s still wasted money when no one’s in the room.
What you can do: Get into the habit of switching lights off. Or better yet, install motion sensors in high-traffic areas like hallways or bathrooms. You don’t need to overhaul your life. Just rethink the things you do every day without noticing. These common habits, when done differently, can lead to real savings over time.
Take Back Control of Your Electricity Bill
If your power bills have been creeping up and you’re not sure why, you’re not alone. The good news is, you don’t need to guess or make extreme sacrifices to cut your costs.
Small, consistent changes in how you use appliances, when you run them, and how you heat or cool your home can make a noticeable difference. These aren’t just energy-saving tips. They’re habit shifts that put you back in control.
And if you want real, ongoing support to keep your energy use in check, it helps to have a provider that’s on your side.

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.

Going solar has been viewed as unattainable for many Australians, specifically with the upfront cost being too high for most. However, come July 2025, that could all change.
The Federal Government has proposed a $2.3 billion rebate program. It is expected to cover up to 30% of home battery installations. If passed, this would be the most significant federal support for solar batteries in Australia to date.
If you are considering solar or adding battery storage, this may be the most significant opportunity in years (pending the election).
At Lenergy, we’ve helped thousands of Australians make smart, future-ready energy choices. In this guide, you will learn:
By the end, you will know exactly where you stand and what steps to take next before the demand surges.
What Is the 2025 Federal Solar Battery Rebate?
On Sunday, 6 April 2025, the Labor Government announced a new Federal rebate for home and business battery storage. The goal is to lower energy bills and improve the stability of the national grid.
If Labor wins the federal election on May 3, the rebate will begin on July 1, 2025.
Here are the key details:
The rebate offers about $358 per kilowatt-hour (kWh) of installed battery storage.
It applies to systems sized between 5kWh and 50kWh.
It covers new solar and battery installations or battery additions to existing solar systems.
It can be combined with the NSW Peak Demand Reduction Scheme (PDRS) for additional savings.
The battery must be installed and switched on after July 1, 2025.
It works as an upfront discount, similar to the way Small-scale Technology Certificates (STCs) reduce the cost of solar panels.
There is one critical limitation: you can only claim the rebate once. If you later decide you want a bigger battery, you will not receive additional federal support. This makes sizing your system correctly from the start very important.
What Are the Key Benefits of the 2025 Federal Solar Battery Rebate?
The proposed rebate offers more than just short-term savings. It creates a real opportunity to lower energy bills, increase energy independence, and future-proof your home or business. Here’s what you can expect if the program proceeds.
1. Up to 30% Off the Installed Cost of a Battery System
The rebate provides an upfront discount of around $350 per kilowatt-hour of usable battery capacity, which typically equates to about 30% off the total installed cost. For many households, this means saving thousands of dollars right away.
2. Significant Ongoing Savings on Electricity Bills
With the right system design, eligible homeowners could see up to 90% reductions in electricity bills. On average, this may amount to savings of up to $2,300 per year, depending on your energy usage and battery size.
3. Available to Homes, Small Businesses, and Community Facilities
The rebate is not limited to residential properties. Small businesses and community organisations are also eligible. For these sites, battery systems up to 50kWh are subsidised, and total system capacity (solar plus battery) can reach up to 100kWh.
4. Works With Existing or New Solar Installations
The rebate applies whether you are adding a battery to an existing rooftop solar system or installing both solar and storage at the same time. This makes it flexible for a wide range of households and businesses.
5. Designed for VPP-Ready Battery Systems
Only Virtual Power Plant (VPP)–capable batteries qualify. While participation in a VPP is not mandatory, the system must meet the technical requirements to be VPP-ready. This helps build a smarter, more stable energy grid for all Australians.
6. One Battery System Per Property
Each eligible property can claim one rebate-supported battery system. This includes rental properties or multiple sites owned by the same individual or business. If you own more than one property, you can apply for separate installations.
How is the Federal Battery Rebate Calculated?
The federal rebate works in conjunction with the STC rebate and is determined by the size of the usable battery capacity (kWh).
For every 1kWh of usable battery capacity, the system would be eligible for 9.3 STC’s (assuming installation occurs in 2025), with each STC valued at $38.50.
For example, the federal rebate generated for a 15.6kWh battery energy storage system would be calculated as per the following:
15.6kWh usable capacity X 9.3 STCs = 145 STC’s
145 STC’s X $38.50 = $5,582.50
By using this formula, you can get a reliable estimate of your potential rebate amount before committing to a battery installation. It’s a smart way to plan ahead and understand exactly how much you could save through the federal scheme if it gets implemented.
How Much Can You Save with the 2025 Battery Rebates?

Am I Eligible for the 2025 Federal Solar Battery Rebate?
Eligibility for the proposed rebate is based on several key criteria. Here’s what you need to know before moving forward.
1. Your Battery Must Be Installed and Switched On After July 1, 2025.
You can begin planning and even install your system now, but the battery must not be turned on or commissioned until after July 1, 2025. This is a strict requirement. If your system is activated before that date, it will not qualify.
2. Your Battery Must Be Between 5kWh and 50kWh.
Only battery systems with a usable storage capacity between 5kWh and 50kWh are eligible. Systems smaller or larger than that range will not qualify under the proposed guidelines.
3. Your Battery Must Be VPP-Capable and CEC-Approved.
The battery must be compatible with a Virtual Power Plant (VPP) and listed on the Clean Energy Council’s (CEC) approved product list. If you are unsure whether your preferred product meets these criteria, our team can help confirm that for you.
4. You Can Only Claim the Rebate Once.
This rebate is a one-time opportunity. If you install a smaller system now and later decide to expand, you will not be able to claim additional rebate support for future upgrades. That’s why sizing your battery correctly from the start is critical.
5. You Must Be Located in Australia.
This is a federal program available to homeowners and small businesses anywhere in Australia. You do not need to live in New South Wales to qualify. However, NSW residents may also be eligible for additional rebates under the state’s Peak Demand Reduction Scheme (PDRS) — up to 28kWh of storage.
If you’re still unsure whether your setup meets the eligibility requirements, we encourage you to get in touch. We’ll assess your situation and walk you through your options, with no pressure to commit.
How Does the Rebate Work?
The proposed federal solar battery rebate will be delivered through the Small-scale Renewable Energy Scheme (SRES), using a system of tradable certificates to fund the upfront discount.
Here’s how it works if ever it gets implemented:
Accredited installers, like Lenergy, will apply the rebate directly to your quote. You won’t need to manage the paperwork yourself.
The installer will handle the certification process with the Clean Energy Regulator.
Once your system is installed and commissioned, the government will buy back the certificates, ensuring the financial support flows through without impacting certificate prices.
The program is uncapped, meaning there is no national limit on the number of households or businesses that can participate. The rebate will be available until 2030, with annual reviews to adjust the subsidy levels in line with changes in battery market prices.
This structure ensures the rebate remains fair, responsive to market conditions, and easy for customers to access without delay or administrative burden.
Is the Rebate Guaranteed to Happen?
No, it is not guaranteed yet.
The 2025 solar battery rebate is an election promise. Labor must win the election on May 3 for the rebate to become law. If they lose, there may be no rebate, or it may take a different form under a new government.
Polls currently show Labor ahead, and there has been no public opposition to the battery rebate proposal. Still, elections are unpredictable.
Talking politics can be a little frowned upon, and we’re not going to tell you how to vote but we know who we’re definitely voting for… *whispers* Labor.
Lenergy is preparing for either outcome. We are offering customers flexible contracts that allow them to benefit if the rebate goes ahead, while protecting them if the political situation changes.
If you act now, you lock in pricing and your place in the installation queue. If you wait, you may be dealing with longer lead times and reduced savings.
What Should You Do to Prepare Between Now and July 2025 When the Government Solar Battery Rebate Starts?
Okay here’s where confusion starts. To be eligible, your battery system must be installed and turned on after July 1, 2025. Does this mean you need to wait until July to start the process? No, you can start as early as today.
Here is the safest path forward if you want to benefit:
Get your system quoted and signed now.
Install your battery before July 1, 2025.
Delay commissioning (turning on) the battery until after July 1, to qualify under the new rebate rules.
By acting early, you protect your rebate eligibility and avoid the bottleneck of installs expected later this year.
If you wait until July to start planning, you may not be able to install until late 2025 or even 2026. That could mean losing thousands of dollars in potential savings.
It is important to know that if the federal rebate does not pass, you will still be responsible for the full cost of the system when it is commissioned.
Frequently Asked Questions About the 2025 Federal Solar Battery Rebate
Who is eligible for the rebate?
Any Australian homeowner or business installing a VPP-ready battery between 5kWh and 50kWh after July 1, 2025, can claim the rebate.
Can I combine the federal rebate with other programs?
Yes. You can combine the federal rebate with Small-scale Technology Certificates (STCs) for solar panels, and with the NSW Peak Demand Reduction Scheme (PDRS) rebate for batteries up to 28kWh, if you are located in New South Wales.
Can I install my battery now and still qualify?
Yes, but there are important conditions. Your battery can be physically installed before July 1, 2025, but it must not be commissioned or switched on until after that date. If you would like help navigating the timing, we encourage you to contact our team for assistance.
What if my battery is already installed?
If your battery has already been installed and commissioned before July 1, 2025, you are not eligible for the rebate. The rebate is intended only for systems installed and turned on after the program officially begins.
Can I add more battery capacity later and claim the rebate again?
No. The rebate is a one-time opportunity per installation. If you expand your battery storage after your original installation, the additional capacity will not be eligible for the rebate.
What types of batteries qualify?
Only batteries that are approved by the Clean Energy Council (CEC) and are sized between 5kWh and 50kWh will qualify for the rebate. If you are unsure whether your preferred product is eligible, please contact us for the latest approved list.
What if I live outside New South Wales?
If you are outside NSW, you will not have access to the NSW PDRS rebate. However, you are still eligible to claim the new federal rebate because it applies nationally.
Will the rebate decrease over time like the STC program?
Yes. If it is legislated, the federal rebate will begin on July 1, 2025, and then reduce each year until 2030. The earlier you install and commission your battery system, the higher your potential rebate amount will be.
Final Thoughts: Should You Wait or Act Now?
The proposed 2025 federal battery rebate is one of the most promising opportunities for Australians looking to invest in energy storage.
However, it is not risk-free. It is not guaranteed yet.
If Labor wins the federal election on May 3, the rebate will move forward. If they do not, the rebate may not happen at all.
However, If you wait until after the election to act, there is a risk you may miss out entirely, or face long delays as installation schedules fill up.
