Can a nonresidential building be excluded from a battery storage system?
Four exceptions can exclude nonresidential buildings from the battery storage system requirements: Single-tenant buildings with < 5,000 square feet of conditioned floor area (CFA). For multi-tenant buildings, the battery storage system energy and power capacities are based on tenant spaces > 5,000 square feet of CFA
Is the battery storage system self-certified?
Yes. The battery storage system is self-certified by the manufacturer to the CEC to meet the JA12 qualifications - PDF to comply with applicable prescriptive and performance requirements in the Energy Code. For more information, please visit the manufacturer certifications of building equipment Battery and Energy Storage Systems webpage.
Does a battery storage system need a rated usable energy capacity?
No. For compliance with the Energy Code the rated usable energy capacity of the battery storage system in kWh must be used for Equation 140.10-B. The usable capacity is the battery energy storage capacity in kWh that a manufacturer allows to be used for charging and discharging.
Are energy storage systems safe?
The emergence of energy storage systems (ESSs), due to production from alternative energies such as wind and solar installations, has driven the need for installation requirements within the National Electrical Code (NEC) for the safe installation of these energy storage systems.
