Tesla turns on Powershare backup for Model 3 and Y

Tesla's Powershare page now says Home Backup is available for new Model 3 and Model Y vehicles ordered in the U.S. and Puerto Rico on or after Oct. 1, 2026, not only Cybertruck. With Powerwall 3 and a Wall Connector, the cars can extend home backup by more than two days at 30 kWh per day; Tesla says some older Model 3 and Model Y vehicles have the hardware, Powerwall 2 and Powerwall+ support is still coming, and Model 3 and Model Y cannot sell power to the grid.
