We’re proud to announce that eFlex 5.4 is now UL 9540 listed. UL 9540 is the latest UL safety standard for energy storage systems (ESS) and equipment. It addresses the safety of ESS intended to store energy from grid, renewable, or other power sources and provide electrical or other types of energy to loads or power conversion equipment. The standard's goal is to ensure that electrical, electro-chemical, mechanical, and thermal ESS operate at an optimal level of safety for both residential and industrial energy users.
