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 is anchored to the highest current Australian regulator-listed model in the exact SDT G2 PLUS+ 4-6 kW subset; larger -SDT-20 codes remain outside the AU range. Scored model: GW6000-SDT-20 · checked 2026-08-07. Evidence.

Strong evidence coverage

20 of 20 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.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.

    AU Support Note

    Current text
    GoodWe's current Australian site separately presents SDT G2 PLUS+ and SDT G3. Its SDT G2 PLUS+ product page, checked 9 October 2026, describes the series as 8-20 kW and lists codes from GW8000-SDT-20 to GW20K-SDT-20; it does not list GW4000-SDT-20, GW5000-SDT-20 or GW6000-SDT-20, although its Datasheet link opens the 4-20 kW sheet cited here. The manufacturer sheet spans 4-20 kW, but the current Australian regulator export lists only GW4000-SDT-20, GW5000-SDT-20 and GW6000-SDT-20 from the PLUS+ code family. Larger -SDT-20 codes are not included in this AU record.
