Image source: Panasonic EverVolt EVHB-I7-X20, the line drawing headed "4 BATTERY CASE" under DIMENSIONS on page 3 of Panasonic's EverVolt Home Battery datasheet; it prints a 73.4 in (1863 mm) height, which the same page's mechanical table gives only for EVHB-I7-X20 (33.5 x 73.4 x 5.8 in). A maker line drawing, not a photograph; the crop leaves out the labels and the height arrows. Figure from the manufacturer's document, page 3.No sellers found.

Charged Reviews classified this product from the documents it is based on. It is our own grouping, not a manufacturer claim.
Printed as "Stackable – connect up to four units together to achieve up to 72kWh of usable storage capacity for whole-home power." and "Installation Method Floor or wall mounted". Classified as Stackable from the maker's own words for this model; the maker also prints wall or floor mounting, quoted here (PM decision, October 13, 2026: a unit printing both stacking words and wall or floor words is Stackable).

Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
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: Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.
AC-coupled · Stackable · 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.
100 evidence points · 45% weight
CEC listing: full credit for the certificate criterion. Exact model found in the dated CEC equipment list. This is not a safety certification or system approval. Applies: CEC; UL 9540; UL 1973.
100 / 100 × 45 = 45 points.
