It needs Tesla backup equipment that safely separates the house from the grid, plus a compatible Tesla Wall Connector (the required equipment depends on the vehicle), all installed with a permit and utility notice. We plan and install the electrical side and coordinate the manufacturer-certified installation where the system requires one, as the Powerwall 3 does.",[10,15,23],{"heading":11,"paragraphs":12},"How it works",[13,14],"When the grid goes down, the backup equipment disconnects your home from the utility and lets the vehicle feed your circuits. When power returns, it switches back. This isolation is what makes it safe for utility workers.","The required equipment depends on the vehicle. Cybertruck can use a Powershare Gateway with a Universal Wall Connector, without a Powerwall. Model 3 and Model Y require a Powerwall 3 and a Universal Wall Connector or Wall Connector (Gen 3), and support is guaranteed only for US vehicles ordered on or after October 1, 2026. Some Model 3 and Model Y vehicles built before that date have the hardware; the car's Software screen, under Additional Vehicle Information, shows Powershare Support if it does.
