The assessment
How it scores, by category
Market position
The data
Warranty coverage: 10-year term
Coverage includes
Parts & labour · term longer than 10 of 49 scored inverters
No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.
System decision
Only exact, manufacturer-named Australian paths are shown. A shared brand, product family or output rating is not proof of compatibility.
Confirmed pairing
The exact named battery pairing is recorded as confirmed for Australia.
Backup: Backup depends on the ET G2, a compatible battery and the exact system wiring in GoodWe's residential solution manual.
Required hardware: GoodWe smart meter; GoodWe smart dongle.
Configuration boundary: Do not mix battery-system versions; the manual permits up to four ET G2 inverters in parallel and specifies model-dependent battery clustering limits.
A documented relation does not establish site sizing, network approval, protected-load design, firmware state or installer acceptance. When no exact relation is recorded, compatibility remains unestablished in this catalogue.
Ask the installer: Will the exact ET G2 model satisfy the site phase, array, MPPT, export-control and local grid requirements?
