Vehicle-to-Home Charging: What It Costs in 2026

“Bidirectional charging” is on the spec sheet of more than 50 EVs sold in the US in 2026. Only about a third of them can actually power your house.

The rest do something real but much smaller: a 120-volt outlet on the car that runs a cooler, a power tool or a laptop. Both features get marketed under the same “bidirectional” banner, and the gap between them is the difference between a camping accessory and a whole-home backup generator. Here is which is which, what powering a house from your car actually costs, and whether it beats the generator you were probably about to buy instead.

V2L, V2H, V2G: three different things wearing one label

V2L (vehicle-to-load) is a 120V, sometimes 240V, outlet built into the car or its charging cable. Output runs 1.5–3.6 kW — enough for a cooler, power tools, a laptop, a camp stove, a window AC unit. No home wiring, no transfer switch, no electrician. It is genuinely useful for camping, jobsites, tailgating and short outages, and it is now common across Hyundai/Kia’s E-GMP platform, the F-150 Lightning, and most BYD models. This is what most “bidirectional” marketing actually means in practice.

V2H (vehicle-to-home) feeds the car’s battery into your home’s electrical panel through a bidirectional charger and a transfer switch, powering some or all of the house the way a standby generator does. This requires real hardware and a licensed installation. Only about 15 of the roughly 54 EVs marketed with some form of bidirectional capability actually support it in the US as of 2026.

V2G (vehicle-to-grid) sends power back to the utility, sometimes for payment. It is the least mature of the three — direct residential V2G enrollment is not available in most US territories yet, and where pilot programmes exist, current annual revenue runs a modest $300–$800.

If a listing says “bidirectional” without specifying which of these it means, assume V2L until proven otherwise. That single check would save most buyers from the wrong expectation.

Which vehicles actually do V2H

GM’s Ultium platform dominates the current list — seven of the eleven shipping vehicles run on it, sharing the same V2H bundle across the Silverado EV, Sierra EV, Equinox EV, Blazer EV and second-generation Hummer EV. If you already looked at our Silverado EV maintenance breakdown, its 200+ kWh pack is exactly what makes it the longest-duration home backup on this list — the same size that made its towing range so heavily affected works in your favour once the truck is parked.

What it actually costs

Equipment alone ranges from about $3,500 for Tesla’s Universal Wall Connector with Powershare up to $7,300 for GM’s Energy V2H Bundle. Add labour, a transfer switch, and often a home gateway, and a full installed system runs $5,000 to $15,000, with most homeowners landing in the $7,000–$9,000 range. A 100-amp electrical panel typically needs upgrading first, adding another $1,500–$3,000.

Ford’s system is the cheapest entry point if you already own or plan to buy an F-150 Lightning: the Charge Station Pro alone runs about $1,300–$1,500, with the full home-integration setup landing around $3,300–$5,310 before labour. Since you would likely buy some kind of home charger for the truck regardless, the marginal cost of adding V2H capability on a Lightning is smaller than the headline figures above suggest.

Is it enough power, and for how long?

Yes, comfortably, for what matters. V2H systems typically output 9.6 to 11.5 kW, which covers a fridge, lighting, Wi-Fi, well pumps, and even a window AC unit simultaneously. Central HVAC may need load management on smaller systems, but essential-load coverage is not the constraint — capacity is.

On duration, the spread between vehicles is large. At an average household’s essential-load consumption of roughly 30 kWh a day:

Now set that against how long an outage actually lasts. JD Power puts the average US outage at 18.2 hours in the South, the region with the longest ones. Even the shortest-duration V2H vehicle on this list covers a typical outage roughly four times over. The multi-day capacity matters for the outlier event — a hurricane, an ice storm, a grid failure lasting a week — not for the routine outage most homeowners actually experience. Buy for the disaster you’re insuring against, not the everyday one; the everyday one is already covered by almost any V2H-capable EV sitting at a reasonable charge.

V2H versus a standby generator

This is the comparison almost nobody makes explicitly, and it should be the first one for anyone weighing the cost.

The installed cost is genuinely similar. What differs is that a generator is a single-purpose asset that sits idle 99% of the time, while V2H hardware sits on top of a car you use every day — the backup capability is close to a free add-on if you were buying the EV regardless. The honest trade-off runs the other way for fuel: a generator with a natural gas line can run indefinitely, while an EV’s home-backup duration is capped by its pack size and needs the grid, solar, or driving somewhere to charge, back to recharge.

Solar changes the maths meaningfully

V2H does not require solar — you can charge the car from the grid and discharge it during an outage regardless. But paired with rooftop solar, the system becomes something closer to a genuinely closed loop: the car recharges from panels during the day and discharges to the home overnight or during an outage, which can theoretically keep a house running indefinitely on sunny days without the grid at all.

This is also where the ongoing savings case, separate from backup power, gets real. Using the EV to store cheap or free solar energy and discharge it during expensive peak-rate hours — time-of-use arbitrage — is claimed to save $500 to $2,000 a year depending on local rates and how aggressive your utility’s peak pricing is. Treat that range as optimistic and site-specific rather than a guarantee; it depends entirely on having both solar and a meaningful gap between your utility’s peak and off-peak rates, which our home charging cost breakdown covers in more detail for rates alone.

What to check before buying in for backup power specifically

1. Confirm true V2H, not V2L. The single most common mistake. Ask specifically whether the vehicle can power your electrical panel through a transfer switch, not just run a 120V outlet.
2. Check your panel amperage. A 100-amp panel commonly needs upgrading before V2H hardware can be installed, adding real cost most buyers don’t budget for upfront.
3. Ask about utility interconnection rules where you live. Some jurisdictions require utility approval for V2H even without grid export; V2G specifically is heavily restricted almost everywhere in the US as of 2026.
4. Decide V2H versus V2L honestly, based on what you actually need. If your real use case is camping, a jobsite, or riding out a brief outage, V2L on a much cheaper vehicle may cover it without $7,000–$9,000 of home hardware.
5. Factor in that this is an EV-plus-hardware decision, not just a hardware one. If you weren’t already planning to buy one of the compatible trucks, the EV itself is the larger cost by far — see our EV versus hybrid comparison for whether that purchase makes sense on its own terms first.

Frequently asked questions

What’s the difference between V2L, V2H and V2G?

V2L is a portable outlet on the car for individual devices, no home wiring needed. V2H powers your home’s electrical panel through a bidirectional charger and transfer switch, like a generator. V2G sells power back to the grid, and is barely available to residential customers in the US as of 2026.

How much does V2H home backup cost?

A full installation runs $5,000 to $15,000 including equipment and labour, with most homeowners landing between $7,000 and $9,000. A panel upgrade, if needed, adds $1,500 to $3,000 more.

How long can an EV power my house?

Depends on the battery and your consumption. At typical essential-load use of about 30 kWh a day, a Ford F-150 Lightning extended-range runs roughly 3 days; a Chevrolet Silverado EV’s larger pack runs 6 to 7 days.

Is V2H worth it compared to a standby generator?

The installed cost is similar. V2H is silent, needs no fuel supply or servicing, and rides on top of a vehicle you already use daily. A generator can run indefinitely on a gas line; an EV’s backup is capped by battery capacity until it can recharge.

Which EVs can actually power a house?

Only around 15 of the roughly 54 vehicles marketed with some form of bidirectional charging in the US actually support true V2H as of 2026. The Ford F-150 Lightning, Chevrolet Silverado EV, GMC Sierra EV, Tesla Cybertruck and select Model 3/Y, and Hyundai/Kia and Nissan models with the right charger are the current shipping options.

Do I need solar panels for V2H to work?

No. You can charge from the grid and discharge during an outage without solar. Solar makes the system more self-sufficient and opens up time-of-use savings, but it isn’t a requirement for basic backup power.

Can I make money selling power back to the grid?

Very limited options exist as of 2026. Where V2G pilot programmes are available, reported annual revenue runs $300 to $800, and direct residential enrollment isn’t available in most US territories yet.

The short version

“Bidirectional charging” on a spec sheet usually means V2L — a camping-grade outlet, not a home backup system. True V2H, which powers your electrical panel like a generator, exists on only about 15 of the roughly 54 EVs claiming some form of the feature, and it costs $5,000 to $15,000 installed. That is roughly generator money, but you get silence, no fuel logistics, and hardware riding on a car you were likely buying anyway rather than a single-purpose asset. Capacity is not the limiting factor — even the shortest-duration V2H vehicle covers a typical 18-hour outage several times over; the multi-day numbers matter for the disaster scenario, not the everyday one. Check panel amperage and utility interconnection rules before committing, and be honest about whether you actually need whole-home backup or whether a cheaper V2L setup already covers what you’d use it for.
