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.
Benchmark anchor. The public family is 8-10 kW; the exact regulator-scored M10 output is 9.999 kW. Scored model: SMILE-M10-S-INV · checked 2026-08-27. Evidence.

Strong evidence coverage
15 of 15 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.

- This is the inverter layer only. Existing AlphaESS battery records remain separate, and no product-pair recommendation is published.
- After
- This is the inverter layer only. Existing AlphaESS battery records remain separate, and no product-pair recommendation is published. The exact M8/M9/M10 inverter manual specifies Smart Fan Cooling, with noise below 45 dB(A) at 1 m. These models are not documented as fanless; natural cooling in the same manual applies to the separate lower-power M5/M3.6/M5-B models.
