Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
Evidence score
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 for this product: Certificate evidence needed; Warranty term needed; Battery conversion efficiency 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.
Research pending, 0 points: Certificates, Warranty term, Battery conversion efficiency, Idle consumption.
Warranty term and battery conversion efficiency are compared with every published inverter; idle consumption with the inverters in the same 7 to 15 kW output band. · Method version 0.5
