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 only · term longer than 13 of 81 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 and displayed range remain inside the exact source and market boundary recorded by the 13 August 2026 sprint. Scored model: H2-10K-S3 · checked 2026-08-13. Evidence.

Strong evidence coverage
17 of 17 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.

- SAJ United States lists H2 split-phase H2-LS-US and B2 High Voltage US Version. Those SKUs are not H2-10K-S3. H2-LS-US, H2-S2 and HS2 are not transferred onto this Australian H2-S3 record. The Australian manual treats H2-10K-S3-A as Australia-only and does not collapse it into H2-10K-S3.
