Published documentation boundary. OUKITEL has not published a datasheet or manual for the EP2500, and the unit was in pre-sale and had not shipped when this record was checked. Two OUKITEL surfaces state different cycle counts: the retail product page states 4000+ cycles, and the Intersolar Europe 2026 release states over 6,000. Neither states the end-of-life retention threshold a cycle claim needs to be scoreable, so cycle life is not scored here. No operating or charging temperature range is published on any OUKITEL surface, and no certification standards are enumerated beyond an IP65 ingress rating. OUKITEL states grid-tied operation and certification for Germany and the Netherlands only. Every figure on this page is limited to what OUKITEL itself states. Source 1.Source 2.Source 3.

Strong evidence coverage
21 of 21 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.
