UL 9540A, Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems, to help manufacturers have a means of proving compliance to the new regulations. Leveraging our long practice of developing standards with vast experience in similar industries, we worked with regulators to understand concerns and deliver a viable test method to accelerate adoption of innovative technology.
UL 1741 SA is the test standard by which we certify that our inverters, Meet HECO Rule 14H Requirements, Meet CA Rule 21 Requirements As more PV is installed on electrical grids, grid operator need flexible tools to help ensure stability and reliability, Starting September 8th 2017, new Installations in HI and CA require inverters to be listed as providing “Grid Support” or “Smart Inverter” functions
ULTRASAFE TECHNOLOGY
These requirements cover batteries for use as energy storage for stationary applications such as for PV, wind turbine storage or for UPS, etc. applications. -- 1.2 These requirements also cover light electric rail (LER) applications and stationary rail applications such as rail substations. These batteries are intended for installation within either the rail car or within a sheltered stationary location such as a rail substation
UL 9540 Energy Storage System (ESS) is comprised of:
A UL 1973-certified stationary battery pack
A UL 1741-certified inverter
Rigorous thermal and electrical testing and evaluation of the UL listed components ensure they are integrated into a safe, high-performance system. With a complete list of PCS Compliance https://www.sol-ark.com/support/
