What is UL 9540?

UL 9540 is a safety standard specifically for energy storage systems (ESS). It covers the safety of ESS, including batteries, inverters, and energy management systems. UL (Underwriters Laboratories) is a globally recognized safety certification company that sets standards and conducts safety testing for various products and industries. So, UL 9540 certification indicates that a particular energy storage system has met the safety requirements outlined in this standard.

What is Rule 21?

Rule 21 refers to the set of requirements established by the California Public Utilities Commission (CPUC) for the interconnection of distributed energy resources (DERs) to the electrical grid. These requirements outline the technical and procedural guidelines that DER systems, such as solar photovoltaic (PV) systems and energy storage systems, must adhere to in order to connect to the grid safely and efficiently. Rule 21 aims to facilitate the integration of renewable energy sources and other DERs into the grid while maintaining grid stability and reliability. It covers aspects such as safety, power quality, and grid support functionalities.
