Evidence score

4/100Missing details20% 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: Certificates evidence needed; Warranty term needed; Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.

AC-coupled · Format not recorded · Usable capacity

The warranty term and the lifetime energy are each scored against the best documented value for a home storage battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.

Lifetime / capacity6,500 cycles4 / 20

Cycle rating disclosed · 20% weight

Documented cycle rating earns 20% of this criterion. More evidence is needed to compare lifetime MWh per kWh.

20 × 0.2 = 4 points.
