Warranty coverage: 5-year term
Coverage includes
Parts only · term longer than 0 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: Argeno 125 (125 kW, three-phase, silicon carbide) · checked 2026-08-22. Evidence.

Strong evidence coverage
20 of 20 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 Argeno 125 current product page, datasheet V02 January 2025, manual and global warranty, rechecked 2026-08-22. India existing-catalogue inverter review 2026-09-02: IN overlays recorded from manufacturer Indian catalogues; scores unchanged.

- The exact scored model Argeno 125 is not named on Fronius India's inverter catalogue. India has no public per-model BIS register, so registration is not independently verified here. Absence from that catalogue is a listing fact, not a quality finding, and does not change the global score. That catalogue names Primo, Primo GEN24, Symo, Symo GEN24, Tauro, Tauro Eco and Eco. Argeno 125 is not among them and is not transferred. Existing AU, US or DE warranty terms are not transferred.
