This project requires updating the photovoltaic system permit to incorporate two Tesla Powerwall 3 ESS batteries totaling 27 kWh, which will serve as the new inverters. The revision includes changes to mounting rails, attachments, and grounding methods, along with replacing the gateway with a Tesla backup switch connected to a protected load panel. No main breaker replacement is needed. All work must meet relevant code and safety standards.
