Latest Residential Solar Battery Brands in Australia 2025

Impressively scalable, the Powerwall 2 can support up to 10 units connected in parallel. This scalability, along with its practical design, positions the Powerwall 2 as one of the best choices for solar battery storage. In 2025, the average price of a 10kW solar battery system (including installation) ranges between $10,000 and $18,000, depending on the brand, installation complexity, and available rebates. In Sydney, the price for a 10kW solar battery system typically ranges from $8,999 to $17,000.
Maybe I forget the extra panel and go back to using our noisy generator to top up. I federal government solar battery rebate intend to ring our caravan service people today but they are beyond busy. For tech-forward homes who desire a powerful backup system, intuitive control, and a high-performing battery, this model is perfect. The Powerwall 3 is a strong rival if you want to equip your house with the best solar battery Australia. One of the best options for solar batteries, it is also a solution that is ready for the future and can be adjusted to meet changing needs.

If you get a regular loan for your battery, your loan provider must itemise the cost of that loan to you.

It suits households looking for a set-and-forget storage solution with built-in management and minimal maintenance. The size of home batteries depends on their energy capacity and their ‘specific energy’, which measures how much capacity they can squeeze into a given volume. If space is an issue, Tesla and Sungrow make space-efficient batteries, whereas the Enphase solution is bloody huge. Installing a solar battery isn’t just a matter of connecting a few wires and it usually takes two people one day.
However, to get you started, this article will cover the most often recommended solar battery storage options in Australia. Overall, BYD Premium Solar Batteries are an excellent choice for anyone looking for a reliable and efficient energy storage solution for their solar energy system. The battery is designed to be compatible with most solar inverters and can be easily integrated into existing solar systems. It also comes with a 10-year warranty, ensuring homeowners can rely on it for years. Sungrow’s high performance, advanced features, and extended warranty period make them a worthwhile investment for those seeking a reliable and efficient energy storage solution. The new B2 series offers a well-made, stackable modular battery that is ideal for backup power.

For a 10kW solar system, most Queensland households will need around a 20kWh to 25kWh solar battery to cover average evening and night-time usage. However, the ideal size varies depending on your lifestyle, appliances, and future energy needs. Sungrow has become a global leader in solar inverter technology due to the company's heavy involvement in research & development of renewable energy solutions. Sungrow is driven by innovation and boasts a broad product portfolio, from basic inverters to large, utility-scale storage systems that consistently outperform competitors.
This can give you a sense of control over your energy consumption and costs, making you less susceptible to external factors. One of the main reasons why you might consider investing in a solar battery is to save money. By storing excess energy generated during the day, you can use it at night instead of relying on the grid, which can lead to significant savings on your electricity bill. This is especially beneficial for households and businesses that use a lot of energy during peak hours when electricity prices are typically higher. The cost of residential solar batteries ranges from $1,000 to $1,200 per kWh of capacity installed. Based on this, the cost of a 10kWh battery could range from $10,000 to $12,000, excluding any potential rebates or incentives.
For a 6.6kW system producing ~9,000 kWh/year in Brisbane (5.5 sun hours), batteries maximize self-consumption, adding to $1,800/year savings. In outage-prone rural Queensland, they ensure reliability, making them a smart investment for many households. It is more economical to include solar battery storage as part of a new solar power system as opposed to adding a battery to an existing system. The ability to provide backup power is one of the key advantages of battery storage, though not every battery is equipped to deliver this benefit. Batteries can provide backup power during a blackout, but the functionality typically works with reduced load capacity.

Often a gateway or an additional piece of hardware will be required for your battery to operate in ‘island mode’ and power your house when the grid goes down. It is important to specify this requirement to your installer to ensure they quote a solution with blackout protection included. While there have been recalls in the past (notably some LG and SolaX models from 2017–2018), these incidents are rare. Over 200,000 home battery systems have been installed in Australia with only a small number of safety issues reported by the ACCC. If your solar panel has a solar controller attached, then you can connect the cables directly to the battery terminals - positive cable to the positive post on one battery. It is more efficient if the solar controller is as close as possible to the batteries rather than at the solar panel, but it will work.
If you buy good solar panels, you can expect them to last for 25 years. The best solar panels will even operate at  90% of their rated output after 25 years. A solar battery lifespan is typically around 10-years, though warranties are often based around the number of cycles and not years. If you regularly cycle (discharge and charge) the battery, the warranty shortens and it won’t last as long. The latest generation from Tesla, the Powerwall 3 is designed to meet the demands of modern solar systems.

It typically comes between 5 and 20 kWh to cater to various energy needs. The Sungrow Battery is a popular choice for homeowners in Australia due to its high efficiency and reliability. It has a capacity of 6.8 kWh and can be expanded to 102.4 kWh with additional modules. Designed with smaller homes and moderate energy demands in mind, the Smile-B3-Plus excels as a straightforward and affordable battery solution. Its 3 kW discharge rate may pose limitations for offsetting high loads, but it shines in environments where energy requirements are more modest.
Longevity and WarrantyOne of the strongest selling points of the Sonnen battery is its outstanding lifespan—offering up to 10,000+ cycles, depending on usage. It also comes with a 10-year or 10,000-cycle warranty, whichever comes first, making it one of the most durable and reliable choices available. If your battery doesn’t charge completely, it’s not wasted—it just means you’ll rely a bit more on the grid that day. Many systems are also designed to optimise charging during shoulder rates or to prioritise essential loads.
