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: S6-EH1P11.4K-H-US · checked 2026-08-08. Evidence.

Sources & references · checked 2026-09-01

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 an independent guarantee that a claim is correct.

Record revision. Solis exact-family user manual version 5.6 released April 2026, current US product page and North American warranty effective 1 July 2025. First-market DE overlay review 2026-09-01: official German catalogues recorded; existing Australian and United States overlays and scores unchanged. Security boundary explained 2026-10-05 using accepted corporate PSIRT/update-cycle and North American cloud-scope sources: exact H-US eligibility/horizon unresolved; logger/cloud assurance not transferred; scores, benchmark and market verification dates unchanged.

    Current US product, support and download pages list the exact S6-EH1P(3.8-11.4)K-H-US family and an April 2026 manual.
    After
    Current US product, support and download pages list the exact S6-EH1P(3.8-11.4)K-H-US family and an April 2026 manual. Solis publishes a corporate vulnerability-disclosure policy, but its eligibility depends on the product security-update cycle. The current schedule lists communication loggers and does not establish a security-update end date or policy eligibility for this H-US inverter. This does not prove support has ended. SolisCloud/app/API certification is separate from inverter firmware signing and secure boot, which remain unestablished for the scored S6-EH1P11.4K-H-US. Confirm the exact inverter and logger support periods separately.
