Technical FAQs 4

What are the UL standards for energy storage systems?

UL 1973: Batteries for Use in Stationary and Motive Auxiliary Power Applications. Safety standard for modules and battery systems used in stationary energy storage systems. UL 9540, Energy Storage Systems and Equipment. Safety standard for energy storage systems used with renewable energy sources such as solar and wind.

What is energy storage container?

SCU uses standard battery modules, PCS modules, BMS, EMS, and other systems to form standard containers to build large-scale grid-side energy storage projects.

What is the regulatory and compliance landscape for battery energy storage?

The regulatory and compliance landscape for battery energy storage is complex and varies significantly across jurisdictions, types of systems and the applications they are used in. Technological innovation, as well as new challenges with interoperability and system-level integration, can also amplify risks.

Do battery energy storage systems comply with building codes?

Building codes: Battery energy storage systems (BESS) must comply with local building codes and fire safety regulations, which can vary across different geographies and municipalities. These codes are governed by the National Fire Protection Association (NFPA) in the U.S. and the performance-based European Standards (EN) in the European Union.
