Warranty coverage: 10-year term
Coverage includes
Parts only · term longer than 13 of 81 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 highest exact current rating established for the retained market scope. Scored model: sonnenBatterie Evo power unit · checked 2026-08-08. Evidence.

Strong evidence coverage
12 of 12 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 correction. Australian Evo datasheet version April 2025, AU/NZ operation manual document 5000611 version 002, March 2026 Australian manufacturer warranty, and CER inverter export data as at 29 July 2026 Corrected 2026-08-26: added not-applicable provenance for Max DC:AC oversizing ratio and Max input current per MPPT (A), mirroring the reviewed architecture_boundary finding already on this record's Number of MPPTs and the not_applicable state the 25 August 2026 inverter-envelope ledger already carries for this exact product. No score change: these two criteria have no specs value before or after, so their missing-mode floor is unchanged. This closes the evidence gap without asserting a number that does not exist for this architecture.
