Answer. The installation codes and standards cited require a residential ESS to be certified to UL 9540, the Standard for Energy Storage Systems and Equipment, and may also specify a maximum stored energy limitation of 20 kWh per ESS unit. The current edition of UL 9540 limits the maximum energy capacity of an individual
Energy storage technologies are advancing rapidly — and standards need to keep pace. By participating in standards panels and industry working groups, UL Solutions helps gather all relevant perspectives, build consensus around safety standards, and create economies of scale. With a robust portfolio of testing and certification services, we
Image: PRNewsfoto/UL. 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,
Northbrook, Illinois – Oct. 13, 2020 – UL, a leading global safety science company, announced today the launch of a free online database recognizing manufacturers who have completed testing under the ANSI/CAN/UL 9540A Standard for Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems (BESS). The
UL''s first requirements for battery safety were developed by our experts more than four decades ago, ultimately laying the groundwork for the first consensus battery standard,

NORTHBROOK, Illinois — Oct. 13, 2022 — UL Solutions, a global leader in applied safety science, today announced that BAE USA''s stationary lead-acid battery energy storage system is the first to be certified to the third edition of ANSI/CAN/UL 1973, the Standard for Batteries for Use in Stationary and Motive Auxiliary Power Applications. BAE USA''s
Exceptions in the codes allow the code authority to approve installations with larger energy capacities and smaller separation distances based on large-scale fire testing conducted in accordance with UL 9540A, the Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems Standard.
An energy storage system (ESS) certified to UL 9540 is primarily comprised of a UL 1973-certified stationary battery that is then evaluated for use with a power conversion system, such as a UL 1741-certified inverter, together as a system.

No. In order to achieve a UL 9540 certification or listing, a residential energy storage system must meet the unit level performance criteria of UL 9540A when the spacing between individual battery energy storage systems is less than 3 ft (0.9 m) in accordance with the installation codes (NFPA 855, IRC).
This is an overall certification for what UL calls "Energy Storage Systems" - ESS for short. A UL 9540 ESS has a UL 1973-certified battery pack (more details below) and a UL 1741-certified inverter (also more information below). It is designed to certify complete systems so you can be sure your battery setup is configured correctly,
