As more Australian households adopt solar energy, the demand for affordable and efficient solar battery systems continues to rise. One name gaining significant traction is Growatt, a well-known Chinese brand that offers solar inverters and lithium battery storage solutions. Let’s get into a detailed Growatt battery review to help you decide if it’s the right choice for your energy needs in 2025.
About Growatt
Founded in 2011, Growatt quickly became one of the top inverter brands globally, with a strong footprint in over 150 countries. In Australia, Growatt has built a solid reputation for offering reliable and affordable hybrid inverters and energy storage systems.
With a dedicated Australian office and local support, Growatt ensures post-installation service and warranty management is accessible, which is crucial for peace of mind when choosing a battery system.
Overview of Growatt Battery Systems in Australia
Growatt’s residential battery solutions are typically designed to work with their own hybrid inverters, making them an attractive option for homeowners looking for an all-in-one solar + battery package.
The flagship energy storage solution from Growatt is the Growatt ARK battery – a modular lithium battery system compatible with the Growatt SPF and MOD series hybrid inverters. These batteries use Lithium Iron Phosphate (LiFePO4) chemistry, known for safety, stability, and long cycle life.
Each ARK module provides 2.56kWh of nominal capacity and can be stacked together, allowing homeowners to scale up based on their energy usage. The ARK system can expand from a small 5.1kWh setup to over 25kWh, making it suitable for both modest and high-consumption households.
Growatt Lithium Battery Range
Growatt offers a diverse range of lithium battery systems tailored to meet the needs of both residential and light commercial users in Australia. Depending on whether you need a single-phase or three-phase solution, there’s a Growatt battery system to match your solar setup.
Below is a summary of the key battery ranges offered by Growatt:

Key Features and Performance
Growatt batteries offer several practical advantages for Australian homeowners. First, the modular design makes it easy to upgrade your battery system in the future. You can start with two or three battery modules and expand later without replacing the entire setup.
The batteries also come with intelligent Battery Management Systems (BMS) that handle cell balancing, over-voltage protection, and temperature control. This extends the lifespan of the battery and ensures stable performance even during periods of peak energy use.
Additionally, Growatt systems are compatible with off-grid and hybrid solar setups, meaning you can use the stored energy when the grid is down or during peak tariff hours, enhancing your energy independence.
With Australia’s increasing exposure to extreme weather and power outages, blackout protection has become a priority for many households. Growatt’s hybrid inverters can provide UPS-like backup functionality, powering essential loads during grid failures.
Price of Growatt Battery in Australia (2025)
One of the biggest selling points of Growatt battery systems is their affordability. Compared to premium brands like Tesla or Sonnen, Growatt offers competitive pricing while maintaining decent performance levels.
As of 2025, a fully installed Growatt battery system in Australia typically ranges from:
- $7,000 – $9,000 for a 5.1kWh system
- $11,000 – $13,500 for a 10.2kWh system
- $17,000+ for systems above 15kWh
These prices vary depending on the installer, location, and whether it’s a new hybrid system or a retrofit. With the Federal Battery Rebate set to roll out in July 2025, Growatt battery installations could become even more affordable for eligible households across NSW, VIC, SA, and QLD.
Warranty and Lifespan
Growatt offers a 10-year warranty on its ARK battery series, which is on par with most major battery brands in Australia. The expected cycle life is around 6,000 cycles, depending on how the battery is used.
Thanks to its LiFePO4 chemistry and advanced battery management, a well-maintained Growatt battery can last between 10 to 12 years with minimal degradation.

In the context of Australia’s solar battery market, Growatt strikes a balance between affordability, functionality, and local support. While it may not have the premium polish or advanced AI features of high-end competitors, it delivers consistent performance for households looking to cut electricity bills and increase self-consumption of solar power.
The company’s focus on modularity, integration with its own hybrid inverters, and support from Australian-based distributors gives it a practical edge for many homeowners.
