Bidirectional Charging and V2H: Can Your EV Power Your House?

Your EV battery holds 60-100 kWh of energy. Your house uses about 30 kWh per day. So in theory, your car could power your home for two to three days during a blackout. That's not theory anymore, it's called V2H (vehicle-to-home), and it's becoming real.
But the technology is still young, and there are important limitations you should understand before getting excited about turning your driveway into a power plant.
What Is Bidirectional Charging?
Standard EV charging is one-way: electricity flows from the grid into your car battery. Bidirectional charging goes both ways, your car can send power back to your home, the grid, or another EV.
There are three flavors:
- V2H (Vehicle-to-Home): Your EV powers your house during outages or peak rates
- V2G (Vehicle-to-Grid): Your EV sells power back to the utility during peak demand
- V2L (Vehicle-to-Load): Your EV powers appliances directly through an outlet on the car
Which EVs Support V2H?
Emporia Vue 3 Home Energy Monitor
Real-time whole-home + circuit-level monitoring, solar/net-metering support, see exactly what your EV costs to charge.
See on Amazon →As of 2026, true V2H capability requires both a compatible vehicle and a compatible bidirectional charger. The list is growing but still limited:
| Vehicle | V2H Support | Notes |
|---|---|---|
| Ford F-150 Lightning | Yes (with Sunrun) | Intelligent Backup Power system |
| Hyundai Ioniq 5/6 | V2L standard, V2H emerging | Needs compatible bidirectional EVSE |
| Kia EV6/EV9 | V2L standard, V2H emerging | Same platform as Hyundai |
| Nissan Leaf/Ariya | V2H via CHAdeMO | Pioneer in V2H but aging connector standard |
| Tesla (all models) | Not yet | Tesla prefers Powerwall for home backup |
What Equipment Do You Need?
V2H requires a bidirectional charger (not your standard Level 2 EVSE) plus an automatic transfer switch or smart panel that disconnects your home from the grid during outages. Total system cost: $5,000-$15,000 installed.
Major bidirectional charger options include the Wallbox Quasar 2, dcbel r16, and Enphase bidirectional EVSE. These aren't cheap, the charger alone runs $4,000-$6,000.
Does V2H Make Financial Sense?
For most homeowners in 2026, V2H is still an early-adopter play. The technology works, but the equipment costs are high and the compatible vehicle list is short.
Where V2H shines is in areas with frequent power outages, expensive peak electricity rates, or existing solar installations. If you already have solar panels and a compatible EV, V2H can create a genuinely self-sufficient energy loop.
For everyone else, standard V2L capability (the outlets on your car) combined with a separate home battery or generator is probably the more practical path for now. Check our Charging Cost Calculator to see whether time-of-use arbitrage makes V2H worthwhile with your local rates.
