Solar battery installers Adelaide.
A battery can dramatically reduce how much power you buy from the grid. With 15+ years of experience, we’ll help you choose the right battery for your home and energy needs.
Thinking about adding a battery to your solar?
Still buying expensive power every night?
Your solar may produce plenty of energy during the day, but without a battery, much of that excess gets exported for a fraction of what it costs to buy power back later. A properly sized battery lets you keep more of the energy you produce and use it when you actually need it.
Confused by battery brands, sizes and conflicting advice?
10 kWh, 20 kWh, AC coupled, DC coupled, Tesla, Sigenergy, Sungrow — it's easy to get overwhelmed. We'll look at your actual energy usage and existing solar system, explain the options that make sense and tell you what we'd install if it were our home.
Want your battery installed properly?
The products we recommend need to meet our standards for quality and reliability. Just as importantly, we take pride in our workmanship, respect your home and make sure every installation is completed to a standard we’re proud to put our name to.
That's where we come in...

Is a solar battery worth it?
For many Adelaide homes with solar, a battery can make a lot of sense. Instead of sending your excess solar back to the grid for a small feed in tariff, you can store it and use it later when your household needs it most.
That means using more of the solar you already produce, buying less electricity from the grid and getting more value from your solar system.
The Federal Government’s solar battery rebate now covers up to 30% of an eligible battery system, significantly reducing upfront costs. Combined with the Solar Sharer’s free charging windows, many homes can add storage without upgrading their existing solar making the investment even more cost-effective.
We work with leading battery brands including Sigenergy, Goodwe, Tesla, Sungrow, Enphase and Alpha ESS, and only recommend solutions that have proven themselves in real Adelaide conditions not just on paper.

There isn’t one “best battery” for every Adelaide home.
Some homeowners prioritise maximum value. Others want seamless blackout backup, EV integration, expandability or the best app and energy management technology.
That’s why we work with a select group of battery manufacturers, giving us the flexibility to recommend the right system for your home and what you want to achieve.
Every battery we recommend has been carefully selected for its quality, reliability and proven performance on Australian homes.
How big a battery does your home actually need?
Bigger isn’t always better. The right battery should be sized around how much energy you use after sunset, how much excess solar you generate, whether you want blackout protection and how your energy needs may change in the future.
The best battery size and setup will always depend on your energy usage, existing solar system and future plans — speak directly with our installers for personalised advice.

Benefits of home battery storage in Adelaide.
Adelaide is one of the best locations in Australia for solar battery storage thanks to abundant sunshine and high solar production potential.
01
Lower power bills
Store excess daytime solar and use it in the evening when electricity prices in Adelaide are typically highest — reducing what you buy from the grid.
02
Get more from your solar
With Adelaide's feed-in tariffs dropping significantly, using your own stored solar power is now a far smarter financial move than exporting it.
03
Greater energy independence
South Australia has some of the highest electricity prices in the country. Storing your own solar reduces exposure to future price rises.
04
Reliable backup during blackouts
Power outages are common across Adelaide. A battery keeps essential appliances running during grid outages — peace of mind included.
05
Reduce your carbon footprint
Storing and using more of your own clean solar means less reliance on fossil fuel-generated grid electricity.
06
Future-proof your home
Prepare for EVs, increased household load, and tariff changes — while keeping the option of partial or full off-grid open for later.

Solar battery questions, answered.
What are the best solar batteries for Adelaide homes?
Our top pick for 2026 is the Sigenergy battery — a fully integrated 5-in-1 home energy system that pairs next-gen storage with EV charging, smart energy management, and AI. We also recommend Tesla, GoodWe, Sonnen, Sungrow and Alpha ESS. The best battery depends on your energy needs, budget and existing solar setup.
What government solar battery rebates are available?
The Federal Solar Battery Rebate is a new initiative covering up to ~$2,950 in rebates (plus potential low-interest loans). It’s especially valuable when paired with existing solar. We handle eligibility and apply the rebate directly to your quote.
How does a solar battery work?
When more solar energy is generated than your home needs, the battery system stores the surplus for later use — typically at night when panels aren’t producing, or when demand exceeds production. It works alongside your inverter and panels seamlessly.
What size solar battery do I need?
The right size depends on daily energy usage, solar output and backup goals. Most Adelaide homes benefit from a 10–15 kWh battery offering enough to power the home through the evening and into the next morning.
Can I add a battery to an existing system?
Yes you can retrofit a battery to most existing solar installations.
The best approach depends on your existing inverter, solar capacity and how the system was originally designed. We can assess what you already have and recommend the most practical way to add storage.
Is a solar battery worth it?
For many Adelaide homes, yes. Solar feed in tariffs have dropped significantly, with many current offers commonly sitting around 2 to 6 cents per kWh, compared with rates of 10 to 16 cents or more in previous years. This means exporting your excess solar is worth far less than it once was, while buying electricity back from the grid can cost many times more.
A battery lets you store more of your excess solar and use it when it is most valuable, particularly during evening peak periods. It also gives you greater flexibility over when you use your stored energy and when you choose to export excess power back to the grid.
With the Federal Government’s Cheaper Home Batteries Program reducing the upfront cost of eligible batteries, investing in battery storage is also more affordable than it has been in the past.
Do I need more solar panels when adding a battery?
Not necessarily. If your existing solar system regularly produces enough excess energy to charge a battery, adding more panels may not be required.
For households with a smaller system or increasing electricity needs, upgrading the solar at the same time can make sense. We look at your actual production and usage before recommending either approach.
The other benefit is utilising free power windows to charge your battery from the grid. These have recently been legislated by the Federal Government in certain areas including Adelaide.

Do I need a new inverter to install a battery?
When you’re installing a solar battery to your home, you’ll need to get a new inverter, unless your existing solar inverter is classified as “battery ready”.
The question is:
Will you be getting rid of your existing inverter and replacing it with a single hybrid inverter (known as DC-coupled installation)?
Or
Will you be keeping your existing inverter and adding a new battery inverter (known as AC-coupled installation)?
This isn’t just a technical detail, it can impact your system’s efficiency, blackout protection, monitoring, and even long-term reliability. The decision changes how your solar panels, battery, and inverter work together and ultimately, how much value you get from your system.

Will my solar battery work during a blackout?
It can, but blackout backup does not occur with every battery and needs to be considered when the system is designed. Depending on the battery and installation, we can configure backup for essential circuits or design a system capable of supporting much more of the home.
If blackout protection is important to you, let us know from the beginning so we can recommend and design the right system.
Can I charge my battery from the grid?
Yes. Many modern battery systems can charge from both your solar panels and the electricity grid.
This opens up opportunities to charge during cheaper electricity periods and use the stored energy when grid electricity is more expensive. Your electricity plan and battery settings play an important role in getting the most from this.

Are home solar batteries safe?
Yes. Quality home batteries are designed with multiple layers of protection and must meet Australian safety and installation standards. Just as important as the battery itself is where and how it is installed.
We only recommend products we’re confident installing in our customers’ homes and ensure every system is installed in accordance with the relevant requirements.

How long does a solar battery last?
Most quality home batteries are designed to provide many years of daily use and are commonly backed by a 10 year manufacturer warranty. Battery life can vary depending on the product, how often it cycles, operating conditions and how the system is used.
This is one reason we place so much importance on choosing proven battery brands with strong Australian warranty support.
Can I expand my battery later?
Some battery systems are modular, allowing additional battery capacity to be added as your energy needs grow. This can be useful if you’re planning for an EV, a growing family or greater energy independence in the future.
If expandability is important to you, we’ll factor that into the battery we recommend from the start.
