Systems containing a battery require a battery schematic diagram which must be included with the project’s Part II application as a stand-alone document at the time of submission.

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. Applications containing a battery take longer to process compared to systems without a battery as schematics require an additional review by a third party, separate from the application. To avoid further delays in application and battery review, 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. 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.
