What to Expect on Your Battery Install Day

Written by Donna Wentworth on . Posted in Installation, Apps & Monitoring, Learning Centre.

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.

How Long Does a Battery Installation Take?

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:

How Does a Virtual Power Plant (VPP) Work?

Want to Join a VPP or Add More Storage Later?

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.

Diagram of how a Virtual Power Plant (VPP) works in conjunction with the grid.

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.

How To Use The Tesla Mobile App

How to Use the Tesla App to Monitor Your Powerwall

Written by Donna Wentworth on . Posted in Installation, Apps & Monitoring, Learning Centre.

At Lenergy, we’ve helped hundreds of Australian families install and manage their Powerwalls. One of the most common things we hear afterwards is: “The Tesla app looks great — but I’m not really sure what I’m looking at.”

The Tesla App is powerful and well-designed, however, if you haven’t had someone walk you through it, it can be hard to know where to start. Some parts are intuitive, others are less obvious — and unless someone has explained things like Backup Reserve or Self‑Powered mode, it’s easy to miss features that could help you get more from your system.

In this article, you’ll learn how to use the Tesla mobile app to monitor and manage your Powerwall. From setup to backup settings to understanding what your battery is doing at any given moment — we’ll break it down, based on real questions we get from Lenergy customers.

By the end, you’ll feel confident using the app to stay informed, stay in control, and get the most out of your energy system.

Why the Tesla App Matters for Your Powerwall

Most of what your Powerwall does happens quietly in the background — charging, discharging, switching between solar and grid. The Tesla app is how you see what’s going on and, importantly, how you control it.

It shows you how your home is using energy in real time: what’s coming in from your solar panels, what’s being stored in the battery, what you’re drawing from the grid, and what’s being exported. This kind of visibility makes it much easier to spot patterns, track your savings, or troubleshoot when something feels off.

But the app isn’t just for monitoring — it’s where you adjust how the Powerwall behaves. For example, you can set aside backup power in case of an outage, or switch to Time-Based Control if you’re on a time-of-use electricity plan. These aren’t just nice-to-have features — they can make a real difference in how effectively your system works for your household.

The bottom line: if you want to get the full value out of your Tesla Powerwall, understanding the app is a big part of it. And once you know what each setting does, you’ll feel more in control of your energy use.

Getting Started: Installation & Setup

Before you dive into the features, it’s worth making sure your Tesla app and Powerwall are properly set up. Most of this is handled during installation, but here’s a quick rundown of what you (or your installer) should have completed:

1. Download the Tesla App

Head to the App Store or Google Play and search for the Tesla app. This is the same app Tesla uses for vehicles, solar, and energy storage — so if you already have a Tesla product, you don’t need a separate download.

2. Create Your Tesla Account

If you don’t already have one, you’ll need a Tesla account to log into the app. This is where your Powerwall system is registered, and it’s what connects your app to your specific hardware. Your installer will typically invite you to join or create your Tesla account during or shortly after installation.

3. Register the Powerwall

Your installer should link your Powerwall to your Tesla account. If that hasn’t happened or you’re taking over a system from someone else, you may need to submit a Powerwall registration request.

4. Connect to Wi-Fi

For the app to work properly, your Powerwall needs a stable internet connection. This is usually via Wi-Fi, but in some cases a wired connection or backup 4G dongle may be used. If your app isn’t updating regularly or is showing offline, this is the first thing to check.

5. Add Additional Users (Optional)

Want a partner, family member or property manager to have access? You can add another user through your Tesla account. Each person needs their own login — you can’t share a single account across devices.

Once the basics are set, the app will start displaying your system’s activity — including solar generation, home usage, battery charge level, and more. From here, it’s time to explore what the app can do.

Backup & Security Features

One of the biggest reasons people invest in a Tesla Powerwall is to keep the lights on during a blackout. The Tesla app makes it easy to manage this — and gives you a clear picture of how much backup power you actually have.

Backup Reserve

This setting lets you choose how much of your battery’s capacity to hold in reserve in case of an outage. For example, if you set your reserve to 20%, the Powerwall will stop discharging below that point — even if you’re using a lot of power — to make sure you’ve got something left if the grid goes down.

The right reserve level depends on your energy habits and your risk tolerance. Some homeowners set it low to maximise daily savings, while others prefer to keep more in the tank during storm season or in areas with unreliable power.

You can adjust your reserve level directly in the app:

  • Tap Settings > Backup Reserve
  • Use the slider to increase or decrease your backup threshold

If your Powerwall ever drops below this level, the app will let you know — so you can choose whether to reduce usage or allow it to dip into your reserve temporarily.

Storm Watch

Storm Watch is Tesla’s built-in safeguard for extreme weather. When enabled, it automatically prepares your Powerwall for outages by charging it to full capacity ahead of severe events like cyclones, thunderstorms, bushfires, or floods.

The system monitors weather alerts issued by the Bureau of Meteorology and will activate Storm Watch when a watch or warning is in place.

You’ll get a push notification when Storm Watch kicks in. From that point, your Powerwall will charge as quickly as possible to 100% to give you the best chance of riding out a grid outage. Once the weather risk has passed, your Powerwall returns to your normal settings.

How to Enable Storm Watch:
 To turn it on:

  • Open the Tesla app
  • Go to Settings > Storm Watch
  • Toggle it on

Note: Storm Watch requires your phone to be paired with your Powerwall and Grid Charging to be enabled. This setting is usually configured by your installer, but if you can’t access it, contact your installer (like Lenergy) for assistance.

If a severe weather alert hasn’t triggered Storm Watch but you’d still like extra protection, the easiest option is to raise your Backup Reserve manually through the app.

See more information here on the Telsa App’s storm watch

Energy Optimisation Modes & Controls

Beyond just backing you up in a blackout, your Powerwall can also help you lower your electricity bills — especially if you’re on a time-of-use plan or generating more solar than you use during the day. The Tesla app gives you several ways to control how your battery behaves, depending on your priorities.

Self‑Powered Mode

This mode prioritises using your own solar energy instead of drawing from the grid. During the day, your solar panels power your home and charge the Powerwall. At night, your Powerwall discharges to supply your energy needs.

If your main goal is to use as little grid electricity as possible, Self‑Powered mode is a good default setting.

You can enable it by going to:

Settings > Open Powerwall Menu > Under Operational Mode, select Self-Powered

Then set your preferred Backup Reserve by adjusting the slider at the top of the screen

Time-Based Control

If you’re on a time-of-use electricity plan (where prices vary depending on the time of day), Time-Based Control helps your Powerwall charge and discharge strategically to avoid high-cost periods.

There are two options:

  • Cost Saving: Designed to reduce your energy bill, even if it means drawing from the grid occasionally.
  • Balanced: Aims to maximise your use of solar while still reducing grid costs.

To enable Time-Based Control, go to Settings > Powerwall > Operational Mode, then select Time-Based Control. From there, tap the Utility Rate Plan card to choose your tariff type (e.g. peak/off-peak or time-of-use). You can also adjust your Backup Reserve using the slider at the top of the screen to decide how much battery capacity to hold in case of an outage.

Once enabled, the Powerwall will begin learning your energy patterns — and over the following weeks, it will start making smarter decisions based on your usage, solar generation, and the tariff schedule you provide.

Advanced Settings

In addition to mode selection, you can adjust more detailed behaviours like:

  • Your energy rate plan (for time-based billing)
  • Whether or not to allow grid charging
  • Your minimum backup reserve, which interacts with whichever mode you’re in

Many of these features work well with the default settings, but if you’re confident using the app, you can adjust them to better align with your household’s energy usage and preferences.

If you’re unsure which settings to start with, we generally recommend enabling Self‑Powered or Balanced mode, then reviewing how your battery performs over a week or two. From there, you can tweak your preferences based on what you see.

Troubleshooting & Common Issues

While the Tesla app is generally reliable, you might occasionally run into issues — especially if your internet connection drops out or if your system settings were never fully configured. Here are some common problems and how to resolve them.

1. Powerwall Appears Offline

If your Powerwall isn’t showing any data or appears offline in the app, the most common cause is a loss of internet connection.

Check these first:

  • Is your home Wi-Fi working?
  • Has your router been moved or changed recently?
  • Has the Powerwall been disconnected from the network?

You can reconnect it by accessing your Powerwall gateway (typically located near your switchboard) or by contacting your installer for support. If the issue persists, Tesla support may need to re-establish the system connection.

2. App Not Updating or Showing Old Data

If the app isn’t showing current information, try force-closing and reopening it. Also check for app updates in your device’s app store.

If your phone is showing older energy data or nothing at all, it may be a sign that your Powerwall has lost connectivity, not that the app is faulty.

3. Need to Restart or Reset Your Powerwall

In rare cases, your installer or Tesla support may advise a system reset — for example, after a major firmware update or configuration change. This shouldn’t be done unless requested, but if needed, Lenergy can walk you through the process or send a technician.

What You Can Control, and What Tesla Manages

The Tesla app gives you more control than most people expect — from setting how your Powerwall responds to grid outages, to choosing how and when it charges and discharges. For many homeowners, that control translates into lower bills, greater energy independence, and peace of mind during extreme weather.

That said, not everything needs to (or should) be manually managed. Tesla’s systems are designed to handle most decisions in the background — learning your usage patterns, responding to your electricity tariff, and adjusting behaviour based on weather conditions. The app gives you the option to fine-tune, but it doesn’t demand constant attention.

If you’ve just had your Powerwall installed — or if you’ve had it for a while but haven’t explored the app — this guide should help you feel more confident navigating the features that matter most.

And if something still doesn’t look quite right, or you’re unsure how to adjust a setting, don’t hesitate to reach out. At Lenergy, we’re here to help you get the most out of your system — long after the installation is done.

Pylontech Battery Review – Is It a Good Fit for Your Home in 2025?

Written by Donna Wentworth on . Posted in Learning Centre, Reviews & Comparisons.

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.

What Is the Pylontech Force H3X?

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.

View full specs on Pylontech’s site

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

Singular module of a Pylontech battery

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.

Which Powerwall 2 Units Are Affected?

The recall only applies to a subset of Powerwall 2 batteries sold between 1 November 2020 and 30 June 2022.

Tesla has already identified the affected units. Customers with these batteries will see a notification in the Tesla app, while installers can confirm via Powerhub, where impacted systems appear with a “Powerwall Low Energy Lockout” alert.

If your Powerwall was purchased outside this date range, or if you own the Powerwall 3, you’re not affected by this recall.

Will My Solar System Still Work Without the Battery?

Yes. If your Powerwall 2 has been disabled, your solar panels will continue to generate electricity as normal. You’ll still be able to use that power in your home during the day.

What you won’t have during this period is backup power or the ability to store excess energy for night-time use. That functionality will return once the Tesla Powerwall 2 replacement unit has been installed.

How Do I Know If I’m Affected?

There are two simple ways to check:

For customers: Open the Tesla app. If your Powerwall 2 is part of the recall, you’ll see a notification explaining the situation.

For installers: Log into Powerhub. Affected systems will show an alert labelled “Powerwall Low Energy Lockout.”

If you don’t see an alert, your system isn’t impacted.

In short, it helps you take control of your energy — so you’re not just hoping your battery is working, you know it is.

How Do You Set Up the Sigenergy App?

Setting up the mySigen app is straightforward, like anything new, it helps to follow the steps in the right order.

Step 1: Download the mySigen App

Search for “mySigen” on the App Store or Google Play. Look for the Sigenergy logo and install the app.

Step 2: Create Your Account

Open the app and tap “Sign Up”. You’ll need to enter your email and create a password. Some installers (like Lenergy) may pre-register your system and provide you with login details.

Step 3: Pair Your System

You’ll be prompted to bind your device — this connects your app to your SigenStor system. You can do this by scanning the QR code on the inverter or entering the device serial number.

Step 4: Allow Notifications

Enable push notifications to receive alerts about system performance or faults.

Step 5: Explore the Dashboard

Once paired, the home screen will show live data for solar, battery, and grid.

What Does the Home Screen Show You?

When you open the app, you’ll see a visual dashboard of what’s happening in your system right now. Here’s what each section means:

  • Home Consumption: How much energy your household is using in real time.
  • Solar Generation: Live solar output from your panels.
  • Battery Status: Charge level, charge/discharge activity, and energy flow.
  • Grid Import/Export: Whether you’re drawing from or sending energy to the grid.

You don’t need to check this every hour — but doing a quick check once a day helps you understand your system’s rhythm.

How Do You Track Your Battery’s Performance Over Time via the mySigen app?

The app also shows historical data so you can track trends over time.

  • Daily / Weekly / Monthly Graphs: Compare your solar production, usage, and battery activity across time periods.
  • Charge Cycles: See how often your battery is filling and emptying.
  • Pattern Spotting: Learn when your battery typically charges, discharges, or runs out of stored energy.

This helps you understand how much of your solar you’re actually using — and when you’re relying on the grid.

What If the mySigen App Isn’t Working or Shows Weird Data?

Things to check:

  • Wi-Fi connection: The app needs a stable internet connection.
  • Refresh the app: Try closing and reopening it if data looks frozen.
  • Look for error messages: Common ones include “system offline” or “device not bound.”

If things still look off, take a screenshot and contact your installer. At Lenergy, we can remotely check for faults and confirm your system is working as expected.

2 batteries side by side: Tesla Powerwall 3 and Anker Solix X1

Tesla Powerwall 3 vs Anker Solix X1: Which Battery Should You Choose?

Written by Donna Wentworth on . Posted in Reviews & Comparisons, Uncategorized.

You’ve just been quoted a battery system, and it’s not the one you expected. Maybe it’s the Anker SOLIX X1 — a name you’ve never heard of. Or perhaps it’s the Tesla Powerwall 3 — which you have heard of, but you’re wondering if it’s still worth the price tag.

No matter which option you’re considering, this is a significant investment — one that affects your household energy costs, your backup power during blackouts, and how future-proof your solar setup will be over the next decade. It’s not just about specs on a datasheet — it’s about making a decision you feel confident with.

At Lenergy, we install both the Anker SOLIX X1 and the Tesla Powerwall 3. We’re not here to push one over the other — because the best battery depends on your needs. What we’re here to do is give you a clear, side-by-side comparison so you can understand the real differences.

In this guide, you’ll learn how each system performs — from backup power to safety, to cost, to what they’re actually like to live with. By the end, you’ll know exactly which battery suits your setup best — and why.

Why Compare the Anker Solix X1 and Tesla Powerwall 3?

If you’re researching solar batteries in 2025, these two names keep coming up: Anker Solix X1 and Tesla Powerwall 3.

On the surface, they seem worlds apart. One’s from a globally famous electric car company. The other? A newcomer to home batteries, best known (until recently) for making power banks and phone chargers.

So why are solar installers — including Lenergy — offering both?

Simple: they each solve different homeowner problems. And they both bring serious capability to the table.

Lenergy achieves sigenergy gold installer status

Lenergy Achieves Sigenergy Gold Installer Status: What It Means for You

Written by Donna Wentworth on . Posted in EV Charging, Uncategorized.

Lenergy has recently been recognised as a Sigenergy Gold Installer — and while that might sound like an industry label, it’s something that brings real value to homeowners considering a battery system.

The Gold Installer status is part of Sigenergy’s official partner program. It’s awarded to installation companies who complete their certified training, meet installation quality standards, and actively support Sigenergy systems in the field.

In other words, it’s not a badge for signing up — it’s recognition for doing the work properly.

For you, this means the team installing your battery:

  • Has completed official product training
  • Understands how to configure the system for performance and safety
  • Has been vetted by the manufacturer for quality and ongoing support

In an industry where not all installations are equal, this kind of third-party recognition helps take the guesswork out. You know the product is solid — and now, you know the installer is too.

Get In Touch With Our Team Today

Sigenergy Gold Installer Status: Why It Matters

As part of our involvement with Sigenergy, our team was recently invited to visit their global headquarters and factory in Shanghai, China.

It was an opportunity to meet with the people behind the product, including Sigenergy’s Managing Director for Australia and New Zealand, Will Hall. Our team took a close-up view of how their systems are designed, tested, and supported. That level of transparency gave us even more confidence in the technology we’re installing — and reinforced why getting the installation right is key.

In short, the trip reinforced why we chose to work with Sigenergy — and why we feel confident bringing their battery systems into homes and businesses across Australia.

Working with a Sigenergy Gold Installer like Lenergy means you’re getting a system that’s not just technically capable, but properly installed and supported. That distinction can make a big difference in how the system performs day to day — and how long it lasts.

Behind the Tech: What Makes Sigenergy Batteries Different?

Sigenergy might be a newer name in the Australian market, however globally, they’ve built a strong reputation around doing the fundamentals well — and building with the future in mind.

Their battery systems are designed to do more than just store excess solar. They’re built to help you use your energy more efficiently, manage your home during outages, and scale up as your needs change.

See our recent article on Sigenergy Is No.1 in Australia Again – 3 Months in a Row

Here are a few features that stand out:

Modular and Scalable

Sigenergy’s batteries are modular, which means you can start with the capacity you need now and add more later — without having to replace the entire system. This is ideal for growing families or households planning to add electric vehicles or other major loads in future.

Smarter Energy Management

Each system is backed by smart software that monitors solar generation, home energy use, and battery charge levels in real-time. It can automatically shift when and how energy is used — helping you rely less on the grid and make better use of your solar.

Designed With Safety in Mind

Sigenergy uses lithium iron phosphate (LFP) battery chemistry — widely considered the safest option for home storage. Their systems also include built-in protection features like thermal monitoring and short-circuit prevention, offering peace of mind without extra complexity.

Clear, Easy-to-Use Monitoring

Through the mySigen app, you can see exactly how much power you’re generating, storing, using, and sending back to the grid — all in real time. It gives you full visibility and control, even if you’re not a tech expert.

Is a Sigenergy Battery Right for Your Home?

Not every home needs a battery. But for many households, adding storage is the next step in getting more value from solar — especially with feed-in tariffs dropping and energy prices remaining unpredictable.

See more information on our recent blog Is Sigenergy Worth the Hype? Everything You Need To Know

So, is a Sigenergy battery the right fit for you?

Here are a few things to consider:

You Use Power in the Evenings

If you’re running appliances, heating or cooling, or EV charging after dark, storing your excess solar during the day can help you avoid high evening grid rates.

Bidirectional EV Charger

You Want Protection from Blackouts

Sigenergy systems can be configured to keep key appliances running during an outage. This kind of backup power is especially useful in areas with unreliable grid supply or for households who can’t afford to lose power unexpectedly.

You Want Room to Grow

As Sigenergy systems are modular, it’s easy to scale your storage up over time. Whether you’re planning to get an electric vehicle or just want to future-proof your system, the flexibility is there without having to start over.

You’re Looking for Long-Term Value

Sigenergy sits in the mid-to-premium price ranges. That positions it below brands like Tesla, while still offering smart energy management, strong safety features, and a solid user experience.

Not every household needs all the features Sigenergy offers — and that’s okay. However, if you’re planning for the long term and want a system that’s smart, scalable, and properly supported, it’s well worth considering.

Why Choosing the Right Installer Still Matters Most

Battery systems are getting smarter. But without the right installation, even the most advanced technology can fall short.

A poorly configured battery might not charge properly. It might fail to deliver backup power when you need it. Or it might quietly underperform for years — costing you money without you even realising it.

Get In Touch With Our Team Today

That’s why choosing the right installer matters just as much as the brand you choose.

As a Sigenergy Gold Installer, Lenergy has been recognised for doing the job properly — through training, real-world performance, and a commitment to long-term support. It means your battery will be installed to the manufacturer’s standards, and supported by a team that understands how to get the most from it.

Anker SOLIX X1 Battery Review: Is It the Right Choice for Your Home in 2025?

Written by Donna Wentworth on . Posted in Reviews & Comparisons, Uncategorized.

You’ve just been quoted a battery you’ve never heard of — the Anker SOLIX X1. You’re probably thinking: “Why this brand? Is it reliable? And why aren’t they offering me a Tesla or something I recognise?”

That’s a fair reaction. Especially when you’re making a five-figure investment that affects your power bills, backup protection, and energy independence for years to come.

At Lenergy, we install the Anker SOLIX X1 because we believe it’s one of the most flexible and safety-first batteries now available in Australia. However, we also know that trust isn’t built with a quote — it’s built with clear, honest answers.

In this guide, you’ll learn exactly what the Anker SOLIX X1 does well, where it may fall short, and who it’s the right fit for. No hype, no jargon — just a straightforward review to help you decide if this system belongs in your home.

Who Makes the Anker SOLIX X1 — And Can You Trust Them?

  • Anker Innovations is a Chinese electronics manufacturer, originally based in Shenzhen and now headquartered in Changsha, Hunan, known for products like power banks, chargers, security cameras and earbuds.
  • Anker Innovations Australia Pty Ltd was established in 2011, offering local presence, support, and distribution partnerships (including MMEM Greentech, One Stop Warehouse and BlueSun Group), backed by a multinational electronics brand with strong safety credentials and growing investment in the Australian market.
  • In 2023, they launched their home energy storage sub‑brand, SOLIX.The Anker SOLIX X1 received Clean Energy Council approval for AC‑coupled models in 2024, and the hybrid—single-phase and three-phase—models were certified in 2025, making them eligible for rebates and installation across Australia.

How Safe and Durable Is the Anker SOLIX X1 Battery?

When it comes to battery storage, safety isn’t a luxury — it’s a must. And in Australia, where systems are often installed outdoors and exposed to heat, salt air, and storms, long-term durability matters just as much.

Here’s how the Anker SOLIX X1 stacks up.

Battery Chemistry: LiFePO₄

The SOLIX X1 uses lithium iron phosphate (LiFePO₄) chemistry — widely regarded as the safest lithium battery type available:

  • Less prone to thermal runaway or fire risk
  • More stable in high temperatures
  • Capable of more charge cycles — often 6,000+

For households with kids, pets, or vulnerable family members — or if the battery will be installed near living spaces — this is a big plus.

Outdoor-Ready: Built for Aussie Conditions

Whether you’re in a suburban street, rural property, or coastal town, the Anker SOLIX is built to handle tough environments:

  • IP65 (AC) and IP66 (Hybrid) ratings for dust and water resistance
  • Operating range from –20°C to +55°C
  • C5-M corrosion rating — suitable for installation near the coast. It must be installed at least 300 m (984 ft) away from the coast specifically.

That said, while the unit can be installed outdoors, the warranty does not cover corrosion or rust. So if you’re installing in a salty coastal environment, consider giving it some physical cover (e.g. under eaves or in a battery enclosure) for peace of mind.

Warranty

  • 10-year warranty on the battery
  • 10-year warranty on the inverter module
  • These are two separate warranties, so a failure in one doesn’t void the other.

Anker also offers local support through its Australian distribution network, and while they’re newer to this market, they have a track record of fast warranty support in their consumer electronics range. See here for further information on Ankers warranty policy.

How Much Does the Anker SOLIX X1 Cost in 2025?

Cost is often the make-or-break factor when choosing a battery — especially if you’re comparing it against more familiar options. The Anker SOLIX X1 offers a competitive price point, particularly given its modular design, safety features, and flexible configurations.

Estimated Installed Price Range

Depending on your system size, installer, and whether you’re going with AC or hybrid:

  • 15kWh system (3 modules) (AC-coupled): from around $9,000-$10,500 installed
  • Additional 5kWh Battery Module $1,484.31
  • Additional 10kWh Battery Module $2,589.81

Rebate amounts depend on battery size, household income, and your participation in a Virtual Power Plant (VPP) if applicable. Your installer can guide you on eligibility and help apply. Contact us at Lenergy to discuss your options.

Who Is the Anker SOLIX X1 Best Suited For — And Who Might Want to Look Elsewhere?

The Anker SOLIX X1 isn’t a one-size-fits-all solution — and that’s exactly the point. It’s designed to be flexible, but that doesn’t mean it’s the right fit for everyone. Here’s who it suits best… and who may want to consider other options.

You’ll Likely Benefit If…

  • You want to start small and scale later.
    The modular design means you can begin with a single 5kWh battery and add more over time without replacing your whole system.
  • You already have solar installed.
    The AC-coupled version integrates cleanly with existing systems — no need to change your inverter.
  • You’re planning a new solar + battery system.
    The hybrid (DC) model is more efficient and enables solar charging during blackouts — a major plus for future-proofing.
  • You live in a coastal or hot climate.
    With high temperature tolerance, C5-M corrosion resistance, and IP65/IP66 ratings, the SOLIX is built for harsh Aussie conditions.
  • You want an affordable, safety-focused alternative to Signenergy.
    The use of LiFePO₄ chemistry means better thermal stability and longer life, often at a lower cost than NMC-based batteries.
  • You’re interested in blackout protection.
     Fast switchover and solid output (6kW+) make it practical for powering essential appliances.
  • You don’t like using apps or computers and would rather just walk over to the battery system to see the display of system charge and performance 

You Might Look Elsewhere If…

  • You want brand familiarity over features.
     If you’re only comfortable with names like Tesla or Sigenergy, Anker’s newer presence in the Aussie battery scene might not offer the peace of mind you’re after — yet.
  • You need more than 30kWh AC capacity today.
    While technically expandable, the CEC currently lists AC models up to 30kWh. If you need a larger off-grid-ready AC system immediately, a larger Sigenergy stack may be more suitable.
  • You’re expecting a battery to recharge from solar during a blackout — but you’ve chosen an AC-coupled setup.
     Only the hybrid version supports solar recharging when the grid is down. This matters if you live in a rural area or experience extended outages.

Will You Miss Out on the Battery Rebate While Waiting for Installation?

Will You Miss Out on the Battery Rebate While Waiting for Installation?

Written by Donna Wentworth on . Posted in Rebates, Finance & Government Programs, Uncategorized.

Will You Miss Out on the Battery Rebate While Waiting for Installation? With battery demand at an all-time high, this is the question every solar homeowner should be asking.

The short answer? Yes — you might, if you leave it too late.

The federal battery rebate drops in value on 1 January 2026. That means your system needs to be fully installed and signed off before the end of December to qualify for the maximum rebate.

Installers are already booking well into November and December. If you wait until late in the year to get started, you could miss the deadline — not because you weren’t eligible, but because your installer simply couldn’t fit you in.

To avoid that, the best move is to start now: get a quote, confirm availability, and lock in your install date early.

The Battery Rebate Cut-Off Is Closer Than You Think

The new Federal Battery Rebate has made home batteries significantly more affordable — and therefore the demand is surging. However the rebate drops in value every year until it phases out in 2030. That’s why thousands of homeowners are now racing to get their systems installed before 31 December 2025 to lock in the maximum savings. This has created a clear bottleneck — with limited installer capacity, long queues, and tighter stock availability the closer we get to the deadline.

If you’re thinking about adding a battery, the best time to act is September, or at the very latest, October 2025. Waiting until later in the year could mean longer queues, fewer choices, and less money back in your pocket.

Read through our recent article here to find out more information on the Federal Battery Rebate.

What Factors Affect How Fast You Can Get a Battery Installed?

Two things determine how quickly your battery gets installed: battery availability and installer workload.

Some battery models are in higher demand than others, and stock can run short — especially as rebate deadlines approach. On top of that, many installers are already booked out weeks, even months in advance, with limited capacity left for the year.

If you’re hoping to install before the end-of-year rebate cut-off, both of these factors matter.

How Long Is the Wait for a Home Battery Right Now?

At Lenergy, we’re currently booking battery installs into late November and December, with only a handful of slots left between now and then. Availability depends on which battery model and system size you choose — some options have quicker turnaround times than others. If you’re aiming to get installed before the rebate drops on 1 January, now’s the time to secure your spot.

If You’re Thinking About a Battery, Don’t Wait to Ask

If you’re considering a battery — or just want to know if your home’s a good fit — now’s the time to start the conversation. With rebate values dropping after December and installer calendars filling fast, waiting could cost you in both money and time.

At Lenergy, we’re happy to talk you through your options, give honest timeframes, and help you choose a battery that suits your budget, timeline, and home setup.

Can You Sell Your Extra Solar Power to the Grid — And Is It Worth It?

Written by Donna Wentworth on . Posted in Learning Centre, Reviews & Comparisons.

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.

State / TerritoryApprox. FiT Range (2025)Notes
NSW4.8–7.3¢/kWhIPART benchmarks for all-day flat rates. Retailers typically offer between 4–10c/kWh, depending on tiered daily thresholds.
Victoria0.04¢/kWhESC has droped the minimum FiT from 3.3c to just 0.04c as of 1 July 2025.
Queensland5–10¢/kWhNo mandatory minimum. Some retailers are offering up to 12¢/kWh bonus rates; legacy high FiTs (up to 44c) remain for early adopters.
South Australia5–12¢/kWhRetailers set their own rates. Top offers are around 10–12c for limited daily export caps.
WA10¢ (evening), 2.5¢ (off-peak)Time-of-use FiTs from Synergy, with significantly higher rates during 3–9 pm.
Other states/territories (ACT, TAS, NT)Varies—typically 5–10¢/kWhRetailer-determined, with some legacy high-rate schemes still active.

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.

Ausgrid charging/export model:

  • Charge: 1.2 c/kWh for exports between 10 am–3 pm.
  • Reward: 2.3 c/kWh for evening exports (4–9 pm).
  • Includes a “free threshold” — a small export cap you can send without being charged.

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:

  1. 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.

  1. 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:

ScenarioRateDaily valueQuarterly 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.
  • Legacy premium FiTs: Legacy tariffs (30-45c/kWh) apply to pre-2011 installations. Rates have decreased as of July 1, 2025, for standard contracts.

Selling to the Grid vs Storing in a Battery

When your solar panels produce more energy than you need, you have two main options:

  1. Export it to the grid and receive a feed-in tariff (FiT).
  2. 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.

How VPPs can improve your returns

  • Higher export rates during demand peaks: Instead of the usual 3–10¢/kWh FiT. Amber for example offers up to $16 / KwH to draw energy from your battery
  • 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.
Diagram of how a Virtual Power Plant (VPP) works in conjunction with the grid.

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.

1. Choose the right retailer and plan

  • Compare FiT rates — some retailers pay 2–3¢/kWh more than others. Find out more in our recent article
  • 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.

Bidirectional EV Charging with the Sigenergy SigenStor: A Complete Guide

Written by Donna Wentworth on . Posted in EV Charging, Uncategorized.

You’ve got solar, you’re eyeing a battery, and your EV is the biggest “battery” you own — but using it to power your home still feels murky. Is bidirectional charging real yet in Australia? What even is it? Will it work with your car? And is a DC charger worth the price compared to a standard wall box, especially with tariffs shifting and evening usage hurting your bill? (NSW’s rising prices and modest feed‑in credits are pushing more households toward self‑consumption.)

In this guide, you’ll get a walkthrough of Sigenergy’s SigenStor DC bidirectional charger — how it fits into a SigenStor solar‑plus‑battery system, what it can and can’t do today, what it costs to install, and which EVs in Australia have been tested.

What is bidirectional EV charging?

The simple version: most chargers only push energy into your EV. Bidirectional charging lets energy also flow out of the EV when you want it.

  • V2H (Vehicle‑to‑Home): your EV helps run your home — for bill savings at night or for backup during outages.
  • V2G (Vehicle‑to‑Grid): your EV exports to the grid (or a retailer/VPP) when prices are attractive.
  • V2L (Vehicle‑to‑Load): a socket to power tools/appliances directly from the car (handy, but separate from whole‑home support).
  • V2X: umbrella term covering the above (home, grid, building, loads).

Why DC matters:

  • AC chargers rely on the EV’s onboard inverter. They’re common (7–22 kW), cheaper, and one‑way in most homes.
  • DC chargers use an external power module to convert power. Sigenergy’s SigenStor module is DC and bi‑directional, so it can charge fast and discharge from the EV back to the home/grid (V2X) when supported by the car and the system. That’s how you unlock meaningful V2H/V2G.

Why Australians care in 2025:

  • Evening grid prices are the sting in the bill, while daytime solar exports are worth less. Using your own solar later — either from a home battery or your EV — boosts self‑consumption and cushions price spikes.

How the Sigenergy SigenStor DC EV Charger Works

The Sigenergy SigenStor DC EV charger isn’t a standalone wall box — it’s an add-on module that works as part of the SigenStor solar-plus-battery system. That integration is what enables its bidirectional capability and high charging speeds.

Diagram showing how the Sigenergy SigenStor DC EV charger works with vehicle-to-home energy flow

Direct DC-to-DC Connection

Most home EV chargers are AC chargers, which feed power into your car through its onboard inverter. This means the car controls charging speed and efficiency. The SigenStor charger, however, uses a DC-to-DC link between your home battery/solar system and your EV’s battery.

  • Result: Less conversion loss, higher efficiency, and faster charge/discharge rates.
  • Speeds:
    • 12.5 kW model → adds roughly 75 km of range per hour.
    • 25 kW model → adds roughly 150 km of range per hour (actual figures depend on the car’s efficiency and charging curve).

Bidirectional Power Flow

The charger can send power to the EV (charging) and from the EV (discharging). This supports:

  • V2H (Vehicle-to-Home) — powering household loads from your EV battery during the evening or a blackout.
  • V2G (Vehicle-to-Grid) — exporting power to the grid when tariffs are high (if supported by your retailer or a VPP program).
  • PV surplus charging — prioritising charging from excess solar generation.

Integration with SigenStor Energy Management

As it’s built for the SigenStor ecosystem, the charger works with Sigenergy’s AI-driven energy management platform:

  • Automatically decides when to charge or discharge based on tariff schedules, solar production, and household demand.
  • Allows manual control via the Sigenergy app for instant override.
  • Can coordinate with the home battery so you decide whether energy sits in the car, in the stationary battery, or both.

Safety and Standards

The DC charger uses the CCS2 (Combined Charging System) standard — the same connector found on most modern EVs in Australia — and includes:

  • IP65 weather resistance for outdoor installation.
  • Overvoltage, overcurrent, and temperature protections.
  • Emergency stop and isolation features for maintenance.

Vehicle Compatibility in Australia (2025)

While bidirectional charging is an exciting concept, it’s only useful if your EV supports it. As of August 2025, Sigenergy has confirmed and tested a short but growing list of compatible EV models in Australia.

Currently Tested & Confirmed Models

From Sigenergy’s own compatibility testing:

  • Volvo C40 Recharge
  • BYD Atto 3
  • Ford F-150 Lightning

These models are confirmed to work with the SigenStor DC charger for both charging and discharging (V2H/V2G), provided the firmware on the vehicle is updated to the tested version or newer.

Future Compatibility

Sigenergy is actively expanding the list of supported models as more EV makers enable bidirectional functionality. Popular models expected to be tested in the next 12–18 months include:

  • Hyundai Ioniq 5 / Ioniq 6
  • Kia EV6
  • Nissan Leaf (latest models with CHAdeMO → CCS2 adapters pending approval)

If you’re considering this charger, it’s important to confirm compatibility with your EV dealer or installer before purchase — especially if your car is not on the official tested list.

Installation and Pricing

The Sigenergy DC EV charger is not a cheap plug-and-play unit — it’s a high-power, bidirectional module that needs to be integrated into your existing or new SigenStor system by a qualified installer.

Pricing (Including Installation)

Model & Install TimingPrice (AUD, incl. GST)
12.5 kW — Installed same day as solar/BESS$6,644.22
12.5 kW — Separate visit$7,222.38

Installation Requirements

  • Must be part of a SigenStor system.
  • Installed by a Clean Energy Council-accredited installer.
  • Suitable for indoor/outdoor mounting.

Pros and Cons

Like any emerging technology, the Sigenergy SigenStor DC EV Charger has clear strengths — but also some limitations you should be aware of before investing.

Pros

  • Fast DC Charging at Home
     With up to 25 kW charging power, it’s significantly faster than most residential AC wall boxes (typically 7–11 kW). This means shorter top-up times and greater flexibility.
  • True Bidirectional Capability
     Supports V2H (Vehicle-to-Home) and V2G (Vehicle-to-Grid), so your EV can act as a large home battery or even earn income from exporting to the grid if your retailer offers a program.
  • High Efficiency
     Direct DC-to-DC transfer avoids double conversion losses, achieving efficiency above 97%, which means less wasted energy and lower charging costs.
  • Seamless Integration with Solar & Battery
     Works natively with the SigenStor system, allowing intelligent energy management and easy switching between EV, home battery, and household loads.
  • Future-Proof Design
     Supports the CCS2 standard and is built to handle the ISO 15118-20 bidirectional protocol, which more EV makers are adopting.

Cons

  • Limited Compatibility Today
     As of 2025, only a few EV models in Australia are officially supported (Volvo C40, BYD Atto 3, Ford F-150 Lightning). If your car isn’t on the list, you can’t use V2H/V2G yet.
  • High Upfront Cost
     $6,600–$9,000 installed is a big investment, especially if your EV can’t yet take advantage of bidirectional functions.
  • Requires Full SigenStor System
     You can’t install this charger as a standalone product — it must be paired with a SigenStor battery/inverter setup, which adds cost and complexity.
  • New Technology Risks
     Bidirectional charging standards are still maturing, and firmware updates (both from Sigenergy and car manufacturers) may be needed for full functionality.

How It Compares

High-power home EV charging is still a niche market in Australia — and true bidirectional options are even rarer. Here’s how the SigenStor DC charger stacks up against other contenders.

Compared to Typical AC Wall Boxes

  • Power Output: Many home AC chargers deliver 7 kW (single-phase) or up to 22 kW (three-phase). While these can be quick, the SigenStor’s 12.5 kW and 25 kW direct DC output bypasses the EV’s onboard inverter for higher real-world efficiency and sustained high-speed charging — particularly valuable for large-battery EVs.
  • Bidirectional Capability: AC units are usually one-way. Even the few AC bidirectional chargers (like the Wallbox Quasar 2) are limited in Australia due to compatibility and certification hurdles.
  • Efficiency: DC avoids the EV’s onboard inverter, reducing losses.

Compared to Other DC Home Chargers

  • Wallbox Quasar 2 (DC, bidirectional): Not yet widely available in Australia, limited to 7.4 kW, CHAdeMO and CCS2 in some markets — but at lower power than the Sigenergy.
  • FIMER & Delta DC Chargers: Offer high-speed DC charging (10–25 kW), but typically lack residential bidirectional capability in Australia.
  • Cost: Sigenergy pricing ($6.6k–$9k installed) is competitive with other high-end DC home chargers, though the SigenStor requirement adds a system cost layer.

Why It Stands Out

  • Integration: The SigenStor module is part of a complete solar + battery ecosystem, enabling smooth energy management without third-party controllers.
  • Higher Power: 25 kW is among the fastest home-capable DC chargers on the market.
  • Bidirectional with CCS2: Future-ready for the standard most new EVs in Australia are adopting.

Where Others Might Be Better

  • If you don’t have (or plan to have) a SigenStor system, a standalone AC or DC charger from brands like Fronius, Delta, or Tesla may be more cost-effective.
  • If you own a CHAdeMO vehicle (e.g., older Nissan Leaf), specialised CHAdeMO bidirectional chargers are more suitable — though their future in Australia is uncertain.

Is It Worth It?

Whether the Sigenergy SigenStor DC EV charger is a smart buy for you depends on your EV, your energy setup, and your goals.

It Makes Sense If:

  • You already own (or plan to buy) a compatible EV like the Volvo C40, BYD Atto 3, or Ford F-150 Lightning — and want to use it for V2H or V2G now.
  • You’re installing a SigenStor solar + battery system and want fast, efficient EV charging built into your energy ecosystem.
  • You have high evening power use or want blackout resilience without buying an oversized stationary battery.
  • You’re in a state with battery rebates or VPP incentives, which help offset the cost.
  • You value future-proofing — knowing more EV models will support bidirectional charging in the coming years.

You Might Wait If:

  • Your EV isn’t yet compatible — you’d be paying for features you can’t use.
  • You don’t plan to install the full SigenStor system.
  • Your driving patterns mean you’re rarely home during the day to charge from solar, limiting V2H/V2G benefits.
  • You’re waiting for more competition in the home bidirectional market, which could push prices down.

The SigenStor DC charger is one of the fastest and most capable bidirectional home chargers available in Australia, however its value hinges on having the right EV and the SigenStor ecosystem in place. If you tick those boxes, it can significantly boost your energy independence and make your EV a genuine part of your home’s energy strategy. If not, you may be better served by a standard AC charger for now — and revisit bidirectional options when compatibility and incentives improve.

Sigenergy Sigen AC EV Charger Review: Features, Costs, Pros and Cons

Written by Donna Wentworth on . Posted in Learning Centre, Reviews & Comparisons.

Choosing the right home EV charger is as important as choosing the car itself. With so many options promising speed, smart features, and solar integration, it can be hard to tell which ones genuinely deliver.

The Sigenergy Sigen AC EV Charger is designed for both standard home charging and full integration with Sigenergy’s SigenStor solar and battery system. In this review, you’ll get a clear breakdown of what it does, how it performs, how much it costs, and when it makes sense to choose it over other chargers.

What is the Sigenergy Sigen AC EV Charger?

The Sigenergy Sigen AC EV Charger is a home and workplace charging solution designed for Australian electric vehicle owners. It’s available in three power levels:

  • 7.0 kW – best suited for single-phase homes and overnight charging
  • 11.0 kW – three-phase, faster turnaround for compatible EVs
  • 22.0 kW – three-phase, the fastest option for home or small business use

All models use the Type 2 connector standard, which is the default for Australian EVs, meaning it’s compatible with the vast majority of vehicles on the market. You can choose between a socket with a shutter (extra safety) or a tethered cable version for convenience.

The “AC” refers to “Alternating Current”, which is the standard voltage that your home runs off already. Why it’s mentioned is because they have an alternative “DC” charger which refers to “Direct Current” which you get straight from your solar and battery system before it converts to the AC power in your home. There are certain benefits to this.

What makes the Sigen AC EV Charger different from a generic wall unit is its ability to work as a stand-alone charger or as part of the Sigenergy ecosystem. If you have a Sigenergy SigenStor battery and solar setup, the charger can:

  • Use surplus solar power to charge your EV, reducing grid reliance
  • Schedule charging based on time-of-use tariffs or your own preferences
  • Coordinate charging with your home battery so you’re using stored renewable energy rather than peak-rate grid electricity

It’s also designed for both indoor and outdoor installation. With an IP65 weather rating and IK10 impact resistance, it can handle Australia’s climate — from heavy rain to blazing summer sun — while being robust enough for garage or driveway mounting. See more in our recent article here.

In short, the Sigen AC EV Charger is pitched as a flexible, future-ready EV charger that suits both new EV owners looking for a reliable home solution and existing solar/battery households wanting to make the most of their renewable energy.

How Much Does It Cost?

The cost of a Sigenergy Sigen AC EV Charger comes in two parts — the charger unit itself and the installation.

Charger-only pricing

  • Sigenergy 7.0 kW EV AC Charger – $1,248.50
  • Sigenergy 11.0 kW EV AC Charger – $1,348.87
  • Sigenergy 22.0 kW EV AC Charger – $1,497.37

Prices above are for the charger only and do not include installation or accessories.

Installation costs

Installation costs can vary widely depending on your home’s electrical setup and where you want the charger installed. Here are the main factors that affect price:

  1. Single-phase vs three-phase
    • Three-phase installations require more expensive cabling and protection devices (2–3× the cost of single-phase in some cases).
  2. Distance from the switchboard
    • Back-to-back installation (charger on the other side of the wall from the switchboard) is quicker and cheaper.
    • If the charger is far from the switchboard (e.g., garage on the opposite side of the house), you’ll need a longer cable run, which adds labour and material costs.
  3. Cable size and voltage drop
    • Longer cable runs require larger cable sizes to prevent voltage drop, which increases cost.
  4. Additional safety devices
    • Installations typically require isolators and RCBO safety protection devices. These are not included with the charger and will add to the cost.

The bottom line

While the Sigen AC EV Charger unit price is competitive, the total cost will depend heavily on your home’s wiring and installation complexity. In some cases, the installation can cost as much — or more — than the charger itself. That’s why it’s worth getting a site-specific quote before you buy. 

Pros and Cons

Like any EV charger, the Sigenergy Sigen AC EV Charger has strengths and trade-offs. Understanding both helps you decide if it’s the right fit for your setup.

Pros

  • Flexible power options – Available in 7 kW, 11 kW, and 22 kW models to suit both single-phase and three-phase homes.
  • Solar and battery integration – Works seamlessly with SigenStor to prioritise renewable energy use.
  • Smart charging modes – PV Surplus, Fast Charging, and Battery Boost options for different needs.
  • Dynamic load management* – Protects your home’s electrical system by adjusting charge rate based on other usage.
  • Weatherproof and durable – IP65 and IK10 ratings make it suitable for indoor or outdoor installation.
  • Multiple connectivity options – Wi-Fi, 4G, and Ethernet, plus RFID card support.
  • OCPP compatibility – Can connect to third-party EV charging networks for more flexibility.

Dynamic load management requires the optional Sigen Power Sensor.

Cons

  • Best features require other Sigenergy products – To unlock full PV surplus and battery boost capabilities, you’ll need a SigenStor system and/or Power Sensor.
  • Limited benefit of higher kW chargers if your EV can’t use it – Many EVs in Australia have onboard chargers limited to 7 kW or 11 kW.
  • Not a DC fast charger – This is an AC unit, so it won’t give you the rapid charging speeds you see at public charging stations.

Verdict on balance

For households with solar and a SigenStor battery, this charger offers excellent integration and smart features. For stand-alone installs, it’s still a solid, durable, and future-ready AC charger — but some of its “headline” benefits won’t be fully utilised without the broader Sigenergy ecosystem.

Is It the Right Choice for You?

The Sigenergy Sigen AC EV Charger isn’t a one-size-fits-all product — it’s a strong option for certain homeowners and less of a priority for others. Here’s how to decide.

Best fit scenarios

You’ll get the most out of this charger if you:

  • Already have (or plan to install) a SigenStor battery – This unlocks PV Surplus, Battery Boost, and advanced load management features.
  • Own rooftop solar – Lets you charge directly from excess solar generation, reducing reliance on grid electricity.
  • Have three-phase power and a compatible EV – Makes full use of the faster 11 kW or 22 kW charging speeds.
  • Want a durable, weatherproof charger – The IP65/IK10 ratings make it ideal for outdoor mounting in all Australian climates.
  • Value smart charging controls – Scheduling, tariff-based charging, and app control help optimise energy costs.

When to consider other options

You may want to look at alternatives if you:

  • Don’t have solar or a battery and won’t be adding them soon — you’ll be paying for features you won’t use.
  • Have an EV with a 7 kW onboard charger but no plans for a three-phase upgrade — a lower-cost 7 kW unit may suffice.
  • Need ultra-fast charging at home — you’d be looking at a DC charger, which is a different category altogether.
  • Don’t already have and are not planning to have a sigenergy inverter / battery eco system/ You could just use any specific charger which could be more affordable.

The middle ground

If you’re planning to expand your home energy setup in the next few years, the Sigen AC EV Charger could still be a good “future-proof” choice. You can use it now as a standard charger, then add solar, battery storage, or three-phase power later to unlock its full potential.

Final Thoughts

The Sigenergy Sigen AC EV Charger is more than a basic wall plug for your electric vehicle — it’s a smart, solar-ready charging solution built for Australian conditions. With three power levels, robust weather and impact protection, and seamless integration with the SigenStor battery, it’s well suited to homeowners who want to maximise their use of renewable energy.

Where it really shines is in solar and battery-equipped homes. In this setup, you can charge directly from surplus PV, tap into stored energy at night, and schedule charging to avoid peak tariffs — all through a single app. If you already have a SigenStor, it’s a natural pairing.

However, if you don’t have solar or battery storage, the extra smart features may go unused, and a simpler (and cheaper) charger could meet your needs just as well. Likewise, if your EV’s onboard charger is limited to 7 kW, the faster models won’t offer a speed boost — though they might still be worth it if you plan to upgrade your car or wiring in the future.

Bottom line: The Sigen AC EV Charger is a high-quality, future-proof option that makes the most sense for solar and battery owners, or those planning to expand their home energy system. For the right household, it’s not just a charger — it’s part of a smarter, greener way to power your driving.
