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 & extendable · term longer than 24 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.

Strong evidence coverage
26 of 26 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.

- Fronius USA's inverter technical-data catalogue lists Primo GEN24 208-240, Primo UL, Symo and Symo Advanced. It does not list Verto Plus. The US catalogue has no Verto Plus family. The exact US technical-data URL for Verto 33.3 Plus returns 404. The US GEN24 UL marketing page is the 208-240 family, which is a separate record.
