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 SH25T; model-specific cooling and current limits are not represented as values for every smaller family member. Scored model: SH25T · checked 2026-08-26. Evidence.

Sources & references · checked 2026-08-30

Strong evidence coverage

26 of 26 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. Sungrow SH15/20/25T datasheet Version 3, SH5-25T manual Version 17, Australian warranty Version 4.2 and current regulator snapshot checked 2026-08-26. First-market US and DE overlay review 2026-08-30: official regional catalogues recorded; Australian overlays and scores unchanged.

    After
    Germany; Sungrow's German service factsheet publishes 10 years for inverters up to 20 kW and 5 years above 20 kW. The scored SH25T is above 20 kW, so the 5-year term applies. That 5-year term is not transferred onto SH15T or SH20T, and the 10-year band is not transferred onto SH25T. The governing German warranty terms remain controlling.

    Before

    After
    Sungrow's United States products catalogue has no residential energy-storage category. The United States residential-energy-storage-system path returns 404. A /us/en product URL that still prints SH15T/SH20T/SH25T and links an Australian datasheet is a CMS locale path, not a United States sale path. Sungrow's US string-inverter range starts at commercial scale. SH5T/SH10T are a different family and already have the same US-unavailable outcome.

    Sungrow's German residential catalogue names SH15/20/25T. SH5T and SH10T are a different scored family even though they share the SH5.0-25T German manual. The broader manual does not make every family member interchangeable.
