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.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The score is anchored to the highest published rating in this exact series. Scored model: Tauro ECO 100-3-D (100 kW, three-phase, Direct wiring) · checked 2026-08-23. Evidence.

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.

Record revision. Fronius Tauro ECO 100-3-D exact page, current Australian Warranty Plus offer and company history rechecked 2026-08-23. First-market US and DE overlay review 2026-08-30: official regional catalogues recorded; Australian overlays and scores unchanged.
