4 FAQs about Standards for home solar container energy storage systems

How many kilowatt-hours can a solar system store?

Systems in these locations are also limited to 40 kilowatt-hours (kWh) of storage capacity. In all other locations noted above, the size limit is 80 kWh. On the exterior walls of the home, it’s important to note that systems cannot go within 3 feet of doors or windows leading directly into the home.

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.

Are energy storage systems required in the 2015 NFPA 1?

While the 2015 versions of the IFC and NFPA 1 do contain some requirements for energy storage systems, they are few compared to the 2018 and 2021 versions. The ESS requirements in the 2018 version, while certainly more restrictive than the 2015 version, are relatively modest.

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).
