Warranty
For batteries bought and installed in Australia from 1 November 2024: 10 years against defects, and a guarantee of 70% of usable energy at 10 years or the model’s minimum throughput, whichever comes first. Batteries installed earlier carry an older warranty with a 60% figure.

Watch for
- You need a compatible hybrid inverter as well
- Older installations have a weaker 60% guarantee
Our take
A good choice when you or your installer prefer a particular inverter, because the battery isn’t tied to one. The Australian warranty is one of the clearest published.
Before you buy
- For the federal battery discount, the exact model must be on the Clean Energy Council’s approved battery list. Ask your installer to confirm it.
- Work out the discount for your battery’s size with our battery rebate calculator.
- Compare quotes from accredited battery retailers near you, and check their accreditation.
