RICH SOLAR's own Limited Warranty page, captured on September 26, 2026. Its WARRANTY PERIOD list gives terms by product category or series, not by stock keeping unit, and marks prorated terms with an asterisk. The manufacturer's published policy, not a certificate.
Manufacturer-operated store product page captured byte for byte and matched to this catalog row on an exact manufacturer SKU match against the published variant SKU RS-B122SP. It establishes what Rich Solar published on that page on the access date: the specification rows printed there, the SKU and barcode in the page's own structured data, the documents linked from it and the photo it shows. Marketing copy, certification wording and stock state on the page remain manufacturer claims that no issuer or laboratory record was read against, and nothing here is carried to another variant.

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; Cell model disclosure evidence needed.
12 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.
Rich Solar publishes "10 Years" against "Warranty" on its own product page for SKU RS-B122SP. The term is the headline figure on that page; the governing warranty document's exclusions, registration conditions and remedy were not read here.
