The assessment
How it scores, by category
Market position
The data
Hybrid inverter
Manages PV, battery DC and household AC through the inverter platform.
- Product role
- The battery remains a separate product even when it belongs to the same branded platform.
- Published range
- 6–15 kW
- Phase
- Three phase
- Backup boundary
- Essential-load capability recorded
What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 10-year term
Coverage includes
Parts & labour · term longer than 24 of 95 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.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Strong evidence coverage
25 of 25 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not a guarantee that a claim is correct.
How far the evidence reaches
2 of 5 questions with checkable rows have a row beyond the maker's claim.
- Output4 checkable rows, none beyond the maker's claim
- Endurance1 of 2 checkable rows beyond the maker's claimMaker-only: 2 design facts
- Safety1 of 2 checkable rows beyond the maker's claim
- Backing2 checkable rows, none beyond the maker's claimMaker-only: 2 maker's commitments
- Fit2 checkable rows, none beyond the maker's claimMaker-only: 9 design facts
- FootprintNot scored for inverters
- Third-party source
- Certified or regulator-listed
- Manufacturer claim
- Reviewed absence
Each bar is one question's checkable rows for this product at true share, stronger tiers first; hatching marks a reviewed absence: not published, we looked. Maker-only rows (warranty terms and design facts that rest on the maker's own documents) are counted under each question, never dropped. review.solar has measured none of these rows itself.

- Current text
- The Australian CEC approved-inverter export dated 24 September 2026 lists exact GW6000-ET-20, GW8000-ET-20, GW9900-ET-20, GW12K-ET-20 and GW15K-ET-20 models to AS/NZS 4777.2:2020 through 29 October 2027.; The exact system manual lists IEC 62109-1/-2, VDE-AR-N 4105 and EN 50549-1. A TÜV Rheinland Australia certificate of suitability published by GoodWe (AZ 69027616, issued under JAS-ANZ accreditation, 17 November 2023 to 17 November 2028) lists the same five models to IEC 62109-1:2010, IEC 62109-2:2011 and AS/NZS 4777.2:2020+A1.
