What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 5-year term
Coverage includes
Parts only · term longer than 0 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.
Benchmark anchor. The score is anchored to the highest published output in this exact electrical and regional series. Scored model: GW20K-SDT-AU30 · checked 2026-07-31. Evidence.

Strong evidence coverage
18 of 18 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 an independent guarantee that a claim is correct.
