Bidirectional Charging During Grid Outages

Bidirectional EV charging remains largely unavailable during grid outages, with Tesla's Cybertruck Powershare the only current system that lets a vehicle recharge from solar panels while powering a home, according to a detailed analysis of major automaker offerings. GM's Energy Home Hub documentation describes discharge-only backup, automatically ending vehicle discharge once grid power returns, while Ford has stopped selling the Charge Station Pro required for the F-150 Lightning's automatic home backup feature, and the Lightning itself has been discontinued. Kia owners face a fragmented option in Wallbox's Quasar 2, which does not support current Kia models, has reported customer difficulties, and cannot run solar charging simultaneously with vehicle-to-home (V2H) discharge. The gap matters because homeowners with solar are effectively pushed toward dedicated stationary batteries like the Enphase 10C rather than using their EV's much larger battery pack. Enphase has announced a bidirectional EV charger targeting volume production in Q4 2026, but functionality depends on automaker enablement and vehicle software, and the author expects delays into 2027. Watch for automaker V2H software updates, Enphase's production timeline, and whether Ford or GM add outage-mode solar recharging.
