Science safety leader UL has created a certification service for energy storage equipment subassemblies (ESES) to achieve UL 9540, allowing large storage assets to procure certified components when building systems.
UL 9540, the most widely used product safety standard certificate for energy storage, has been available to energy storage systems (ESS) for a while.
This move creates a way for the systems’ component subassemblies to be certified before assembly into a full ESS.
An energy storage system’s typical subassemblies would include the connection/metering subassembly, power conversion subassembly, the battery modules, and auxiliary service…
