Tesla is expanding its Powershare Home Backup feature to allow Model 3 and Model Y owners to use their EV batteries as a backup power source. This capability requires owning both a qualifying vehicle and Tesla’s Powerwall 3, though support for older Powerwall models is coming soon. The company states that Premium and Performance models can extend home power for over two days during an outage.

This update applies only to vehicles ordered from October 1st onward, as earlier models lack the necessary PCS2 Lite inverter. Currently, the feature is available exclusively in the US and Puerto Rico, while support remains unavailable for Canada or larger Model S and X vehicles. Other manufacturers like Kia, GM, and Nissan also offer vehicle-to-home charging capabilities.
