Warranty
EcoFlow’s Australian product page gives the single-phase inverter 15 years, the 5 kWh battery pack 15 years, and the 8 kWh pack 10 years with an optional 5-year extension. Its Australian warranty page publishes the inverter warranty policy (version 1.4, from 14 August 2026) but not a battery policy, so ask for the battery warranty terms, including how much capacity it must keep.
Support in Australia
EcoFlow has an Australian site with an installer program and local support.
Strengths

Our take
A scalable all-EcoFlow system with long headline warranties. Get the battery warranty document, and the usable capacity, before you compare it with others.
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.
