Brand and product reliability guide

Updated 17 October 2026 · General information only, not personal financial or electrical advice.

We don't publish paid rankings. Use these criteria to judge any brand yourself.

Minimum bar

• On the CER approved battery list. Only listed products are eligible for the rebate (Clean Energy Regulator).
• Usable capacity, continuous power and backup capability are all stated clearly on the datasheet.

Long-term confidence

• An Australian office or local entity. Is there a local entity that honours warranties if your installer closes?
• Time in the Australian market. Is there a track record of warranty claims being honoured? Search forums for "[brand] warranty claim".
• Monitoring app and firmware support. Ask what happens if the cloud service shuts down.
• Spare parts and service network near you.

Warning signs

• A brand you can't find outside one installer's website.
• A warranty offered only by the installer, not the manufacturer.
• Capacity quoted only as nominal kWh.
• Unusually low prices with no clear reason.
