Tesla’s Model 3 sedan and Model Y SUV finally get Vehicle-to-Home (V2H) bidirectional charging, something the Cybertruck already offers.Not all new 3s and Ys are compatible, as the feature requires a specific new piece of hardware.For either model to feed electricity to a home, the dwelling must have one of Tesla Energy's Powerwall 3 home battery backup systems and a compatible Tesla Wall Connector.
