Jinko ESS has held a ceremony marking its SunTera ESS receiving UL 9540A 6th Edition (2026 Draft) Large-Scale Fire Test certification from the CSA Group during the recent Energy Storage International Conference and Expo in Beijing. The certification confirms that the SunTera liquid-cooled ESS has successfully contained fire within a single enclosure, preventing any propagation to adjacent units, thus validating its system-level safety performance.
Wu Wei, Commercial Director of CSA Group China’s Industrial Unit, commented: “The test was conducted in accordance with the CSA C800 standard and the recently released UL 9540A 6th edition draft. With rigorous test conditions and thorough data collection, the results demonstrate that the SunTera system effectively mitigates fire spread risks. This validates that Jinko ESS’s system-level fire safety design meets the applicable global standards and regulatory requirements.”
Carl Yang, Product GM at Jinko ESS added:“As a globally recognized certification body, CSA Group plays a critical role in verifying fire safety through rigorous evaluation and certification. This certification confirms our capability to help deliver energy storage solutions that are validated under extreme conditions. Moving forward, we will continue to leverage extreme testing to transform edge-case scenarios into standard design considerations, advancing energy storage safety from a qualitative promise to a quantifiable, engineered outcome.”
