Bidirectional EV charging during grid outages remains largely unavailable
Key points
- GM V2H is discharge-only during outages.
- Ford F-150 Lightning V2H system discontinued.
- Kia's V2H has implementation issues and solar limitations.
- Tesla Cybertruck with Powershare supports bidirectional charging.
- Enphase bidirectional charger is projected for late 2026/2027.
Limited V2H Functionality
Many manufacturers offering Vehicle-to-Home (V2H) capabilities, such as GM, design their systems for one-way power flow. During a grid outage, the GM Energy Home Hub disconnects the home from the grid and allows the EV to discharge power. However, these systems typically do not support recharging the EV from home solar or other sources while the grid is down.
Discontinued and Problematic Solutions
Ford's F-150 Lightning previously offered automatic home backup power, but the required Ford Charge Station Pro is no longer available for sale. This suggests a discontinuation of the feature, and even when available, it did not support bidirectional charging during outages. Kia's V2H solution, the Wallbox Quasar 2, has encountered customer issues and does not work with current EV models, nor does it allow simultaneous solar charging with V2H.
Tesla's Bidirectional Capability
The only system identified that supports bidirectional charging during a grid outage is Tesla's Powershare with the Cybertruck. This setup allows the Cybertruck to recharge from a UL 1741-listed solar system if included in the backup circuit. However, this option requires purchasing a Cybertruck, which may not be a practical solution for all consumers.
Future Developments and Delays
Enphase is developing a bidirectional EV charger, with volume production targeted for Q4 2026. This timeline is subject to change and may slip into 2027. Furthermore, the functionality and vehicle compatibility will depend on automaker enablement, software, and final product specifications, meaning specific new EVs would be required to utilize this technology.

Reporting from
Current Vehicle-to-Home (V2H) systems from manufacturers like GM and Ford primarily offer one-way power discharge during outages, without allowing the EV to recharge from solar or other sources. The Ford F-150 Lightning's automatic home backup system is no longer sold, and Kia's V2H solution faces implementation issues and limitations. Only Tesla's Powershare with the Cybertruck currently supports bidirectional charging during an outage, allowing the vehicle to recharge from solar.
