The data
Warranty coverage: 10-year term
Coverage includes
Parts & labour · term longer than 6 of 38 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.
Two things to check
Ask the installer: Will the exact GW9.99K-EHB-AU-G11 model satisfy the site phase, array, MPPT, export-control and local grid requirements?

Limited evidence coverage
8 of 27 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.
