Your EV is a battery.
Use it like one.
Vehicle-to-home technology lets your electric vehicle power your house during outages — turning your car into a 60–100 kWh backup battery that costs nothing extra.
Power flows both ways.
Here's how.
Standard EV chargers only push power one direction — from grid to car. A bidirectional charger reverses that flow. When the grid goes down, your EV automatically switches to home power mode, keeping your circuits running from the energy stored in your car's battery.
Which EVs support
vehicle-to-home?
V2H requires both a compatible vehicle and a bidirectional charger. The list of compatible vehicles is growing rapidly — here are the confirmed models available in the US today.
Tesla vehicles do not support direct V2H. However, a Tesla solar + Powerwall system provides equivalent home backup functionality.
Three components.
One backup system.
A complete V2H setup requires three things working together. Sol Country connects you with licensed installers who handle all three.
Bidirectional charger installed: $2,000–4,500. Transfer switch: $500–1,500. Federal 30% EV charging tax credit may apply to charger cost.
