Our take
A sensible choice with a SolaX hybrid inverter, backed by a clear Australian warranty. Ask for the usable capacity of the size you’re quoted.
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.
