Warranty coverage: 10-year term
Coverage includes
Parts only · term longer than 13 of 70 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 uses the named exact German benchmark; larger stacks, paid states and nearby generations do not transfer evidence. Scored model: PLENTICORE L G3 20.0 · checked 2026-08-16. Evidence.
Australian warranty decision
0 product records
Read the Australian warranty as a claim pathway: the headline term is separate from remedy, labour, freight, site work, transfer and registration conditions.
No available Australian warranty decision record is published for this product. No coverage is inferred.

Strong evidence coverage
15 of 15 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.
