Tesla has officially enabled the Cybertruck Powershare feature to operate in tandem with the Powerwall 3. This integration allows the electric vehicle to serve as a backup power source alongside existing home battery systems, extending the total runtime by more than three days.
The company notes that the 123 kWh battery pack of the Cybertruck provides energy capacity equivalent to nine additional Powerwall units. The system is designed to coordinate power delivery between the vehicle and the home battery without requiring a network connection.
To utilize this functionality, users must install a Universal Wall Connector and a Powershare Gateway. The cost for this hardware installation typically starts at approximately $4,000, though some owners have reported receiving significantly higher price quotes.
The development process faced delays due to technical challenges in synchronizing two grid-forming devices across different hardware generations. Tesla initially projected a 2025 release, later shifting the timeline to mid-2026 before the final rollout.
This update completes Tesla's consumer-focused vehicle-to-grid strategy. Previously, the company launched vehicle-to-grid programs in Texas in February and California in April, establishing the Cybertruck as a functional grid asset.
