What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 25-year term
Coverage includes
Parts only · term longer than 88 of 93 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 preliminary exact sheet is scored only where its values are explicit. Scored model: IQ9N-A-INT · checked 2026-08-27. Evidence.

Strong evidence coverage
14 of 14 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.
Record revision. Exact technical and warranty sources plus CER source version dated 20 August 2026, checked 2026-08-27. First-market US and DE overlay review 2026-08-30: official regional catalogues recorded; Australian overlays and scores unchanged. Inverter operating-envelope refresh 2026-08-31: remaining peak, weighted, oversizing or thermal gaps closed as scoped reviewed absences.

DE Support Note
- Before
- Not previously recorded
- After
- Enphase's German store lists IQ9N-A-INT. IQ9N-A-DOM-US is a different SKU and is not this record. The INT sheet remains the specification source; distributor stock is not inferred.
US Support Note
- Before
- Not previously recorded
- After
- Enphase's United States store page for IQ9N Microinverter names SKU IQ9N-A-DOM-US. The IQ9 series page also names IQ9N-3P-277-A-US. Neither is IQ9N-A-INT. IQ9N-A-INT is not treated as a US counterpart part.

DE Grid and installation context
- Before
