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 by a licensed electrician with a permit and utility notice.",[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 and a Universal Wall Connector or Wall Connector 3, and support is guaranteed only for US vehicles ordered on or after October 1, 2026.
