Evidence score

20/100Missing details45% 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; 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.
