Our take
A large-capacity option. Compare usable capacity, not nominal, and get the warranty terms with your quote.
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.
