Warranty coverage: 5-year term
Coverage includes
Parts only · term longer than 0 of 95 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.

Market context
Global evidencechange in the site menu
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
21 of 21 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 a guarantee that a claim is correct.

- Reviewed absence
Each bar is one question's checkable rows for this product at true share, stronger tiers first; hatching marks a reviewed absence: not published, we looked. Maker-only rows (warranty terms and design facts that rest on the maker's own documents) are counted under each question, never dropped. Held rows have no value, and each says why: not yet confirmed for the exact product, published but not matched to a rubric band, set by paired equipment, or not applicable. They are not scored and are counted under each question, never drawn. review.solar has measured none of these rows itself. How the evidence puzzle works

IN Support Note
- Before
- Not previously recorded
- After
- 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.
