Jinko ESS, the energy storage arm of JinkoSolar, has announced that its testing center has received accreditation from the China National Accreditation Service for Conformity Assessment (CNAS). The center meets the international ISO/IEC 17025 standards in both technical competence and management practices. With this accreditation, its test results will now be recognized across over 100 member countries of the International Laboratory Accreditation Cooperation (ILAC).
The testing center focuses on energy storage systems (ESS), power conversion systems (PCS), and other core equipment and critical components. Spanning 7,000 m², the laboratory is equipped with over 500 high-precision instruments covering system functionality and performance, electrical safety, environmental adaptability, and other technical areas.
Previously, the lab qualified as a witness testing facility by both CSA Group (Canada) and TÜV Rheinland (Germany). Earlier this year, Jinko ESS was included in BloombergNEF’s (BNEF) Tier 1 Energy Storage Provider List for Q1 2025.
