GoodWe's two-page English datasheet for the ET PLUS+ Series 16A (GW5KN-ET, GW6.5KN-ET, GW8KN-ET, GW10KN-ET), footer GoodWe-Single page-20240306-EN-V2.1, served from en.goodwe.com, captured on October 24, 2026. Its Technical Data table has one column per model; only the GW5KN-ET, GW6.5KN-ET and GW8KN-ET columns are read, each record from its own column, and a value printed once across the columns is read as printed for all four. It is older than the user manual, which is primary. Manufacturer claims, not independent tests.

It covers sixteen models; its Technical Parameters tables (section 10.1) print one column per model in groups of four. Only the columns of GW5K-ET, GW6.5K-ET, GW8K-ET and GW10K-ET (PDF pages 78 to 82, printed pages 74 to 78) and GW5KN-ET, GW6.5KN-ET and GW8KN-ET (PDF pages 83 to 87, printed pages 79 to 83) are read, each record from its own column. Breaker and cable recommendations are read only where they name the model or apply to every model in the manual. Manufacturer claims, not independent tests.

Evidence score

15/100Missing details15% documented

The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.

Missing details. This number counts only the evidence recorded so far. The source review for this product is not finished, or the maker has not disclosed enough, so the number can only go up.

Missing for this product: Certificate evidence needed; Warranty term needed; Idle consumption needed.

Each input is scored against the best documented value for an inverter: warranty term and battery conversion efficiency against every published inverter, idle consumption (lower is better) against the inverters in the same output band, or against every published inverter when the output is not documented. A documented value always earns points; an undisclosed one earns 0 and is listed as missing. Researched products receive a score. Certificates earn points for the evidence itself. Size and weight do not affect scores.
