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 13 of 70 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.
