Warranty coverage: 10-year term
Coverage includes
Parts only · term longer than 24 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.

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. Inverter operating-envelope refresh 2026-08-31: remaining peak, weighted, oversizing or thermal gaps closed as scoped reviewed absences. First-market US and DE overlay review 2026-09-01: official regional catalogues recorded; Australian overlays and scores unchanged.

AU Warranty conditions
- Current text
- labour: Covered transport, travel, and labour are capped together at AUD 200.; registration: Use a sonnen-certified installer or repairer and retain the Installation Certificate and Commissioning Report. Required claim details include name, address, product, serial number, first-service date, authorised partner or certified installer number, and fault description. Contact the Authorised Partner first. Claim within six months of discovering a fault or when it becomes reasonably apparent, and no later than three months after warranty expiry. Remote internet software updates and prescribed network-connection examinations are warranty conditions; no permitted offline duration is quantified. Separate pre-registration beyond these records is not established.; remedy: sonnen or its Authorised Partner may assess remotely, repair, or replace with a refurbished sonnenBatterie of the same type; refurbished parts may be used. Physical repair or collection is from the original delivery location. For valid claims, combined transport, travel and labour cover is capped at AUD 200; for claims outside cover, the owner bears those costs. The instrument does not promise a fresh ten-year or minimum replacement term. Australian Consumer Law rights remain additional, including the separate major-failure remedies; uncapped removal and reinstallation are not promised.; removal reinstallation: No uncapped removal and reinstallation entitlement is stated.; transferability: Prior written sonnen consent is required; consent will not be unreasonably withheld.; transport: Covered transport, travel, and labour are capped together at AUD 200.

AU market evidenceAU market evidence+4 in JSON recordAU Warranty scope
- Before
- The integrated power unit is covered as a sonnenBatterie component under the March 2026 Australian warranty issued by sonnen Australia Pty Ltd.
- After
- The integrated Evo power unit is covered as a component of the Australian sonnenBatterie under sonnen Australia Pty Ltd's March 2026 warranty. Cover starts when the system is first brought into service, as recorded on the Commissioning Report, and ends at the earlier of ten years or 10,000 complete recharge cycles. Partial charges and discharges aggregate into complete cycles; this is a warranty limit, not an independently measured inverter lifetime.
