Details
Charged Reviews classified this product from the documents it is based on. It is our own grouping, not a manufacturer claim.
Printed as "Each Stack contains 2-8 modules (4.8 kWh each)." and "Mounting Options Floor Standing". 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).

HomeGrid's own two-page LV Stack'd Series specification sheet, linked as "Stack'd Series" under Specification Sheets on its Downloads page and captured on September 24, 2026. Most figures are printed per stack of 2 to 8 modules, with a BMS and base, and cannot be assigned to a single module; only the Options table and the per-module energy are read for module records. Certificates and warranty are printed for the series.

Printed for the series as "Warranty 10 Years", with "Our warranty is per component to support upgradability." HomeGrid's US warranty (April 1, 2023) does not list product number 4000051, so the terms that apply to this module are not established.

Evidence score

20/100Missing 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 energy disclosure evidence needed; Lifetime / capacity evidence needed; Cell model disclosure evidence needed.

Stackable · Expansion · Rated capacity

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

Warranty term10 years20 / 20

10 years · 20% weight

This is the best documented for an expansion battery, printed by the maker. 17 expansion batteries share this value.

Printed for the series as "Warranty 10 Years", with "Our warranty is per component to support upgradability." HomeGrid's US warranty (April 1, 2023) does not list product number 4000051, so the terms that apply to this module are not established.

100 / 100 × 20 = 20 points.

Printed as "UL 9540" in the Certificates row of HomeGrid's LV Stack'd Series specification sheet (21240.3P-Oct25), for the series rather than for product number 4000051 by name. HomeGrid's Downloads page labels its UL 9540 certificate "LV Stack'd Series UL 9540 (with Sol-Ark)" and the sheet names Sol-Ark 12K/15K as the on-grid UL 9540 inverters, so the listing applies to that system pairing; the certificate was not read. Recorded as the manufacturer's claim.
