Warranty
Sigenergy’s Australian warranty covers the battery and energy controller for 10 years and guarantees 70% of usable energy at 10 years or a minimum throughput, whichever comes first. The warranty requires the system to stay online: after 90 days without a connection it goes into a safe operation mode. Newer 6 and 10 kWh modules are also listed; check the current datasheet for their usable capacity.
Support in Australia
Sigenergy has an Australian company (Sigenergy Australia Pty Ltd) and publishes Australian warranty documents.

Our take
A flexible all-in-one for a new system, letting you size the battery in steps. Make sure your installer gives you the current Australian warranty and that you can keep it connected.
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.
