WHY IT MATTERS

Your EV is already a battery on wheels.

A typical EV holds 80–130 kWh — five to ten times what a stationary home battery holds. With the right hardware, that battery can keep your house running for days, not hours.

🏠 Whole-home backup, on wheels

✓ Days of runtime, not hours

When the grid goes down, your EV powers your house. We install the transfer equipment and the panel work — you plug in and live normally.

💰 No second battery to buy

✓ You already own the expensive part

You paid for the battery in your driveway. V2H lets it do double duty — backup power without buying a stationary battery, or alongside one for layered coverage.

📉 Charge cheap, where plans allow

✓ Overnight rates, verified — not advertised

Where Dominion's Off-Peak Plan is available at your address (smart meter required — you check eligibility in your own Dominion account, and we walk you through it), overnight charging runs about 13.4¢/kWh. Some co-ops go far lower. We quote your utility's real numbers, never a brochure's.

THE WALLED-GARDEN TRUTH — READ BEFORE YOU BUY ANYTHING

Every carmaker's V2H system only works with its own vehicles: Tesla's box powers your home from a Tesla, GM's from a GM. No system on the market today powers your home from another brand's EV — and "one system, everything talks" is a story, not a product. If you're between vehicles or planning a purchase, tell us — the hardware choice should follow the vehicle, not the other way around.

Driving something not on this list? Call anyway — rollouts move quickly, and a home battery can bridge the gap until your platform lands.

FAQ

V2H questions, answered honestly.

Which EVs can power a home today?

Three platforms work right now: Tesla Powershare (Cybertruck only, for now), GM Energy V2H (Silverado EV, Blazer EV, Equinox EV and more of the Ultium lineup), and the Kia EV9 via the Wallbox Quasar 2 bidirectional charger. We install the first two on Central Virginia homes today and can quote the EV9 setup.

Can my Model 3 or Model Y power my house?

Not yet. Powershare is Cybertruck-only today. Tesla has said it will expand — but we don't install promises. When it ships, this page will say so; we review it monthly.

Can my EV work through any brand's charger?

No — and anyone who says otherwise is selling a story. Every carmaker's system is a walled garden today. A brand-agnostic option (Enphase's bidirectional charger) is slated for volume production late 2026; we're tracking it.

Do I still need a home battery if I have V2H?

They do different jobs. A stationary battery covers the house automatically every time — even when the vehicle is away or low. Your EV brings far more total energy for the long outages. Many homes start with one and add the other; we'll show you which order makes sense for yours.

What does a V2H install involve?

Transfer equipment, the manufacturer's home hardware, and panel work — sized to your service and your vehicle. Most installs are one to two days on site, plus permitting and inspection, which we handle. For Powershare, Tesla publishes typical costs: hardware around $1,950 and installation typically $2,000–$4,000 depending on your home's configuration — and if you already have a Powerwall and Wall Connector, no additional equipment is needed at all. Either way, you'll get the exact, no-fee price before any work starts.
