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 - PDF. The usable capacity is the battery energy storage capacity in kWh that a manufacturer allows to be used for charging and discharging.

Are battery & energy storage systems CEC certified?

A list of certified batteries is available on the CEC website. covered by warranty or 70% of nameplate capacity under 10-year warranty. Do battery & energy storage systems need to be certified to the CEC to meet Reference Joint Appendix JA12 requirements? Yes.

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

What does kWh Batt & kW PVDC mean?

kWh batt = Rated useable energy capacity of the battery storage system in kWh. kW PVdc = PV system capacity required by Section 140.10 (a) in kWdc. B = Battery energy capacity factor specified in Table 140.10-B for the building type. D = Rated single charge-discharge cycle AC to AC (round-trip) efficiency of the battery storage system.

Does art 690 apply to a photovoltaic battery system?

If you have batteries for photovoltaic (PV) systems, the additional requirements of Art. 690, Part VIII apply. But covering a battery system from square one to end of life requires far more knowledge than what is in Art. 480 (see SIDEBAR: Beyond Article 480).
