For systems containing a battery, a battery schematic diagram must be submitted with the project’s Part II application. The Program reviews every battery schematic to verify it demonstrates that the system shall be electrically connected in a manner that ensures non-solar generated electricity used to charge the battery is not metered as solar generated power. To avoid delays in application review and approval, AVs are advised to check that the information in the schematic is complete and comprehensive before submitting the application, that the box indicating if a project includes a battery storage system is accurately marked, and that the battery schematic is included in the application. Battery schematics are reviewed separately from the application by a third party and should be stand-alone documents. Important details include, but are not limited to, the PV, inverter, ESS type and capacity, conductor size, and breaker information. Do not include specification documents unless accompanied by a detailed schematic.
