The Australian solar market is not just growing, it’s surging. This surge is driven by the increasing demand for home battery storage, a trend set to revolutionise how we power our homes. These innovative batteries, such as those offered by Sungrow and Soltaro, enable you to store surplus solar energy during the day, reducing your reliance on the grid and significantly lowering your electricity bills. This makes investing in solar energy and home battery storage a smart and cost-effective choice for Australian homeowners, and you could be part of this important trend.
Two prominent players in the Australian battery storage market are Sungrow and Soltaro. Both offer compelling options, but each has its unique selling points. Sungrow, with its global reach and scalability, offers a solution for those looking for a reliable and versatile system. On the other hand, Soltaro, with its local expertise and simplified installation, caters to homeowners who value ease and efficiency. This article delves into a detailed comparison of Sungrow vs Soltaro batteries, helping you decide based on your specific needs and priorities.

Company background
- Sungrow: Since 1997, Sungrow has established itself as a global leader in solar inverter technology, operating in over 150 countries. Their comprehensive range of solar solutions, including batteries, is a testament to their reliability and innovation, making them a trusted choice for homeowners worldwide.
- Soltaro: Established in 2011, Soltaro is a proudly Australian-owned company specialising in energy storage solutions. They design, manufacture, and assemble their batteries in-house, focusing on the Australian market.
Battery technology and performance
- Chemistry: Sungrow and Soltaro primarily utilise Lithium Iron Phosphate (LiFePO4) batteries. Compared to other chemistries, LiFePO4 offers a longer lifespan, higher safety rating, and better tolerance for high temperatures, making it ideal for the Australian climate.
- Cycle life: This refers to the number of complete charge-discharge cycles a battery can endure before its capacity degrades significantly. Sungrow batteries boast a cycle life exceeding 6,000, while Soltaro claims over 10,000 cycles for their flagship AIO series. While Soltaro seems to have a paper edge, the reality is that most homeowners will experience a small difference within the typical lifespan of a solar system (around 20-25 years). Both batteries offer excellent durability.
- Usable capacity: This is the amount of energy you can draw from the battery compared to its total capacity. Sungrow batteries typically offer a higher usable capacity, meaning more stored solar energy is readily available for your home. This can be crucial for maximising self-consumption and reducing reliance on the grid.
System design and compatibility
All-in-one (AIO) vs. modular design: Soltaro focuses on AIO systems, where the battery, inverter, and Battery Management System (BMS) are integrated into a single unit. This simplifies installation but limits scalability. Sungrow offers both modular and hybrid inverter options. Modular designs allow for a more flexible system that can be easily expanded if your energy needs increase. Hybrid inverters offer greater compatibility with existing solar setups and provide more control over energy management.
Warranty and after-sales support
- Warranty period: Sungrow and Soltaro offer industry-standard battery warranties, typically 10 to 12 years.
- After-sales service: Sungrow, a global leader in solar technology, boasts an extensive network of certified installers and service partners across Australia. This ensures readily available support in case of any issues. Information on Soltaro’s service network is less readily available, so it’s crucial to inquire with your chosen installer about their after-sales capabilities.
Here’s a table summarising the key points to consider when comparing Sungrow and Soltaro batteries:
Feature | Sungrow | Soltaro |
Brand origin | Global | Australian |
Product range | Diverse battery capacities & inverter options | Primarily All-in-One (AIO) systems |
Inverter compatibility | A wide range of Sungrow hybrid inverters | Integrates with most inverter brands | Primarily designed for Soltaro inverters |
Battery chemistry | Various chemistries, depending on the model | Primarily Lithium Iron Phosphate (LiFePO4) |
Potential advantages | Scalability, global reach & support | Local expertise, simplified installation (AIO) |
Additional considerations
- Price: While both brands offer competitive pricing, Sungrow batteries might be slightly more affordable due to their modular design and higher usable capacity. It’s always best to get quotes from several installers to compare pricing for complete solar and battery storage systems.
- System monitoring: Both companies provide system monitoring capabilities, allowing you to track your energy production, consumption, and storage levels remotely. However, Sungrow’s monitoring platform is known for its user-friendliness and advanced features, providing a more comprehensive picture of your solar system’s performance.
