6 FAQs about [Energy storage inverter safety standards]

What are the electrical installation requirements for inverter energy systems?

This Standard specifies the electrical installation requirements for inverter energy systems and grid protection devices with ratings up to 10 kVA for single-phase units, or up to 30 kVA for three-phase units, for the injection of electric power through an electrical installation to the electricity distribution network.

What is a UL 9540 certified energy storage system?

A UL 9540-certified energy storage system (ESS) must use UL 1741-certified inverters and UL 1973-certified battery packs that have been tested using UL 9540A safety methods. The batteries and inverter inside such a system have all met product safety standards.

Do energy storage sites have different safety codes and standards?

Yes, different safety installation codes and standards are used for energy storage sites with large utility-owned systems where the inverters and batteries are housed in separate locations and the entire project is often far from other buildings. For instance, the 1,600-MWh setup at Moss Landing in California follows these specific codes and standards.

What is the energy storage standard?

The Standard covers a comprehensive review of energy storage systems, covering charging and discharging, protection, control, communication between devices, fluids movement and other aspects.

Are large-scale energy storage systems safe?

Large-scale energy storage systems pose a greater risk for property and life loss than smaller systems due to their size. NFPA 855 requires 3 ft of space between every 50 kWh of energy storage for safety. However, the Authority Having Jurisdiction (AHJ) can approve closer proximities for larger storage systems based on thermal runaway test results from UL 9540A.

Do energy storage systems need a CSR?

Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation’s safety may be challenged in applying current CSRs to an energy storage system (ESS).
