Batteries

The Energy Commission does not require submittal of information to the solar equipment lists as a condition for complying with Title 20 appliance efficiency standards or for installing equipment in California. Some utilities or local governments may use the Energy Commission’s solar equipment lists during their interconnection or permit application processes.

Note #1: The Battery List only includes electrochemical batteries.
Note #2: “JA12” references the 2022 or 2025 Building Energy Efficiency Standards' Reference Joint Appendix 12 (JA12). This appendix outlines requirements for field assembled battery energy storage systems to qualify for the compliance credit or the prescriptive requirements of the battery energy storage system as required. Y (2022) corresponds to batteries that comply with JA12 requirements of the energy code cycle 2022 and before, and Y (2025) corresponds to batteries that comply with JA12 requirements of the energy code cycle 2025 and before.

Note #3: Maximum continuous discharge rate as stated by the manufacturer on the spec sheet.
