What are the fire and building codes for energy storage systems?
However, many designers and installers, especially those new to energy storage systems, are unfamiliar with the fire and building codes pertaining to battery installations. Another code-making body is the National Fire Protection Association (NFPA). Some states adopt the NFPA 1 Fire Code rather than the IFC.
What are non-residential storage requirements?
For storage capacities that exceed these limits, non-residential requirements come into play (NFPA 855 Chapters 4-9). Fire detection, including smoke and heat alarms, vehicle impact protection with approved barriers, and ventilation requirements for chemistries that produce flammable gas during normal operation are addressed.
Can energy storage systems be installed in certain areas?
Energy storage systems can pose a potential fire risk and therefore shouldn’t be installed in certain areas of the home. NFPA 855 only permits residential ESS to be installed in the following areas:
What is the maximum energy rating per ESS unit?
The maximum energy rating per ESS unit is 20 kWh. The maximum kWh capacity per location is also specified—80 kWh when located in garages, accessory structures, and outdoors and 40 kWh in utility closets or storage spaces. For storage capacities that exceed these limits, non-residential requirements come into play (NFPA 855 Chapters 4-9).
What are NFPA 855 size limitations?
Size limitations The residential chapter of NFPA 855 addresses the installation of residential ESS units between 1kwh and 20 kwh. After individual units exceed 20kWh it will be treated the same as a commercial installation and must comply with the requirements of the rest of the standard.
