GoKawiilTesla extends Powershare home backup to Model 3 and Model Y
Tesla has expanded its Powershare Home Backup feature, previously exclusive to the Cybertruck, to Premium and Performance Model 3 and Model Y vehicles paired with a Powerwall 3. Tesla says these EVs can power a home for over two days during an outage, less than the three-plus days claimed for the Cybertruck. Support for Powerwall 2 and Powerwall Plus is said to be coming soon, and the feature currently applies only to vehicles ordered from October 1st onward in the US and Puerto Rico.
GoKawiil's interpretation of the reporting above, not reported fact.
The rollout brings Tesla's vehicle-to-home charging to its highest-volume models rather than just its niche truck, which could make bidirectional power backup more common among everyday EV owners. However, the restriction to newer vehicles with a specific inverter, and the lack of support in Canada or for Model S and X, suggests the feature's reach is still limited for now. Tesla also continues to lag rivals like Kia, GM, and Nissan, which have offered similar vehicle-to-home or vehicle-to-grid capabilities for longer.
- Powershare Home Backup now extends to Premium/Performance Model 3 and Model Y, not just Cybertruck.
- Feature requires a Powerwall 3 and only applies to vehicles ordered from October 1st onward due to inverter hardware needs.
- Currently limited to the US and Puerto Rico, excluding Canada, Model S, and Model X.
