SolaX solar battery systems are designed to help homes and businesses get the most out of their solar power. By storing extra energy generated during the day, these batteries allow you to use solar electricity at night or during power outages, cutting your reliance on the grid and helping lower electricity bills. With reliable performance and advanced technology, Solax batteries offer a durable and efficient energy storage solution—perfect for anyone looking to save money, increase energy independence, and make their home or business more sustainable.
SolaX Power started in 2007, founded by CEO Li Xinfu, with its headquarters in Hangzhou, China. Today, the company has six offices worldwide, employs over 2,000 people, and generates around USD $142 million in annual revenue. SolaX is well-known for its affordable solar inverters and entered the battery market in 2018, releasing several generations since, with the latest “Triple Power” range focused on residential use.
All SolaX batteries are developed and manufactured using in-house technology. In Australia, the listed address is 21 Nicholas Drive, Dandenong South, which belongs to distributor Raystech—indicating that SolaX does not maintain a dedicated local office for direct customer support.
Choosing a Solax solar battery makes sense for homeowners and businesses who want to get more value from their solar system. Solax focuses on practical, reliable energy storage that helps you cut electricity bills, improve energy independence, and stay protected during power outages. Whether your goal is to reduce reliance on the grid, lower your carbon footprint, or simply keep essential appliances running when the power goes out, Solax offers a balanced solution that’s built for everyday use.
Solax solar batteries are available in a range of capacities, typically starting around 5 kWh and scaling well beyond 15 kWh. Thanks to their modular design, you can start small and expand later as your energy needs grow. A lot of users find this flexibility useful, especially if their household energy usage increases over time.
Solax batteries use modern lithium-ion technology, which delivers higher energy density, faster charging, and a longer service life compared to older battery types. Lithium-ion chemistry also offers better thermal stability and requires very little maintenance, making it a dependable option for long-term home energy storage.
With round-trip efficiency exceeding 90%, Solax batteries ensure that most of the energy you store is available when you actually need it. They’re capable of supporting essential household loads, backup circuits, and even higher-demand appliances during peak usage periods.
Solax batteries are designed with space efficiency in mind. Their compact size allows for flexible installation, whether indoors or outdoors. The weather-resistant housing means they’re built to handle a wide range of environmental conditions without compromising performance.
Solax backs its battery systems with a 10-year warranty, giving users confidence in long-term performance and capacity retention. For many households, this warranty plays a big role in feeling secure about the investment.
Integrated smart monitoring lets you track energy generation, storage, and usage in real time. The advanced Battery Management System (BMS) continuously protects the battery by preventing overcharging, deep discharging, and overheating, while also helping the system run as efficiently as possible.
Solax’s battery lineup is built around its high-voltage lithium iron phosphate (LiFePO₄) storage platform, known as the T-BAT HS series. Instead of offering many fixed-size batteries, Solax takes a modular approach. You’ll mainly see two module sizes—3.6kWh and 5.1kWh—which can be stacked to create systems ranging from small residential setups to much larger storage solutions.
A lot of installers point out that these batteries are DC-coupled, meaning they must be paired with a compatible Solax inverter. This design helps improve efficiency but does mean you’re more or less locked into the Solax ecosystem.
This option uses 3.6kWh nominal modules, with around 3.2kWh of usable energy per unit. The real advantage here is flexibility. Modules can be stacked vertically, letting homeowners scale their system over time as energy needs grow.
These batteries are commonly used in residential and light commercial systems. For larger setups, Solax allows parallel connections using a two-in-one cable, which helps extend both capacity and system lifespan. Features like soft-start technology also add an extra layer of protection during operation.
The larger module option offers 5.1kWh nominal capacity, with about 4.6kWh usable per module. This version is often chosen when fewer modules are preferred but higher storage is still needed.
This setup is especially popular in homes using hybrid inverters, where wall space is available and a clean, compact installation is preferred. A lot of Aussies find this option strikes a good balance between capacity, flexibility, and ease of installation.
Solax Module 3.36 battery systems are available in multiple capacity options, making them suitable for both residential and commercial energy storage needs. The 14.4kWh system Solax battery price approximately $10,359, making it a suitable entry-level option for residential use. The 21.6kWh system Solax battery price approximately $13,169, while larger storage options such as the 32.4kWh system Solax battery price approximately $16,965. For higher energy demands, the 43.2kWh system Solax battery price approximately $21,038 and the largest option, the 50kWh system Solax battery price approximately $23,090, before any Australian government rebate is applied.
👉 After applying the Australian Federal Government battery rebate, the cost of Solax Module 3.36 systems is significantly reduced. The 14.4kWh system Solax battery price approximately $5,520, while the 21.6kWh system Solax battery price approximately $5,911. The 32.4kWh system Solax battery price approximately $6,078, the 43.2kWh system Solax battery price approximately $6,522, and the 50kWh system Solax battery price approximately $6,790, making large-capacity systems far more affordable.
Solax Module 5.1kWh battery systems are designed for users who require higher power output and scalability. The 20kWh system Solax battery price approximately $13,677, suitable for medium to large households and small commercial applications. The 30kWh system Solax battery price approximately $17,471, while the 40kWh system Solax battery price approximately $21,801, offering scalable energy storage solutions before the Australian rebate is applied.
👉 After the Australian Federal Government home battery rebate, Solax Module 5.1kWh systems become more cost-effective. The 20kWh system Solax battery price approximately $6,957, the 30kWh system Solax battery price approximately $7,391, and the 40kWh system Solax battery price approximately $8,361, significantly reducing the upfront investment for high-capacity battery storage.

SolaX backs its TriplePower batteries with a 10-year warranty, ensuring long-term reliability. The warranty guarantees that the battery will maintain at least 70% of its nominal capacity by the end of the term. If you plan to expand your system, note that SolaX requires consent if the existing battery is over 1 year old, helping ensure compatibility and continued performance.
Deciding whether a Solax solar battery is right for you really depends on what you need from your energy setup. If you’re building a new system or already have a Solax inverter, it’s a solid choice. The battery is flexible, modular, and easy to monitor, which a lot of homeowners find really convenient.
On the other hand, it’s not perfect for everyone. If your system requires an AC-coupled battery, or you want strong local support directly from the manufacturer, you might want to explore other options. You might notice that Solax performs best when it’s part of its own ecosystem, rather than mixed with other brands.
In short, for new installations or homes already using Solax inverters, the battery offers dependable performance, room to expand, and good overall value. But if you prioritise flexibility or long-established local support, it’s worth comparing it with other brands before making a decision.
