Tesla Enables Cybertruck-Powerwall 3 Backup, Adding Over 3 Days of Home Power

Summary
Tesla has activated Cybertruck Powershare integration with Powerwall 3, letting the truck and home battery work together during outages and extending backup by more than three days.
Tesla says that added capacity is equivalent to about nine extra Powerwalls, using the truck’s existing battery instead of requiring homeowners to buy and install another battery unit.
The update fixes a missing piece in Powershare: Cybertruck could already run appliances, another EV and whole-home backup, but until now it could not coordinate with an existing Powerwall.
Powerwall 2 and Powerwall+ support is still due later this year after delays Tesla previously blamed on certifying how two grid-forming devices share control of a home during an outage.
The rollout broadens Cybertruck’s energy role as Tesla also expands grid-support programs in Texas, positioning the vehicle as both backup storage and a potential grid resource.
