Read from the Deye SE-G5.1 Pro-B series brochure for North America (20260907 v1.0) on deye.com, SE-G5.1 Pro-B parameter table. The rows "Nominal Voltage ( V ) Operating Voltage ( V ) Energy ( kWh ) Usable Energy ( kWh ) [1]" read "51.2 43.2 ~ 57.6 5.12 5.12 50 100 150", so usable energy is 5.12 kWh; footnote: "[1] DC Usable Energy, test conditions: 100% DOD, 0.5C charge & discharge at 25℃." The same table recommends a 90% depth of discharge. Corrected on 25 September 2026: the catalog had published 4.6 kWh, cited to Best Solar Bundle (bestsolarbundle.com). The Best Solar Bundle listing stated 4.6 kWh, which is about 90% of 5.12 kWh; Deye prints a DC usable energy of 5.12 kWh measured at 100% DOD. Earlier note: "Value exactly as Best Solar Bundle prints it in its own "Tech Specs" table on this listing. This is the affiliate distributor's statement about the part it says it ships; it is not a manufacturer figure and no test condition is published beside it. Deye's own page does not print usable energy for this model."

    North American brochure PDF for the SE-G5.1 Pro-B series, archived 20 September 2026. Its feature text is readable but the specification table is set in embedded fonts that did not extract reliably, so no numeric value in this manifest is read from it; it is kept as the archived manufacturer original.

Evidence score

49/100Missing details65% 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: Warranty term needed; Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.

48 V · Format not recorded · Rated 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.

CertificatesCEC · UN 38.3 +6CEC listed45 / 45

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.
