A Ford F-150 Lightning has 131 kWh of battery storage -- nearly 10x a Tesla Powerwall. With a bidirectional charger, that EV becomes your home's backup power system and TOU optimization tool. This guide covers V2H-capable vehicles, compatible chargers, solar integration, NJ utility policies, and real cost comparisons.
Quick Answer
Vehicle-to-Home (V2H) technology lets NJ homeowners use their EV battery (60-100 kWh) as home backup power — 4-7x the capacity of a Tesla Powerwall. V2H-capable vehicles include Ford F-150 Lightning, GM Ultium models, and Hyundai Ioniq 5. Combined with solar panels, V2H can power a NJ home indefinitely during outages.
V2H reverses the normal charging flow. Instead of the grid charging your EV, your EV charges your home.
During the day, solar panels charge your EV for free. A 8 kW NJ system produces ~30 kWh/day -- enough for 100+ miles of driving or full home backup.
Your EV's battery stores 65-200 kWh depending on the model. At $0.26/kWh (PSE&G avg), that's $17-$52 worth of stored electricity.
The bidirectional EVSE converts DC battery power to AC household power. Output ranges from 3.6 kW (Ioniq 5) to 10.2 kW (GM PowerShift).
Via a transfer switch, EV power feeds your home panel. During outages, it isolates from the grid. During normal operation, it offsets peak TOU rates.
Not every EV supports V2H. Here are the models currently available with bidirectional charging capability.
Most established V2H platform; automatic transfer switch included
Largest battery capacity; PowerShift includes panel integration
V2L built-in via adapter; full V2H requires third-party EVSE
Pioneer of V2H; CHAdeMO standard limiting future charger options
Three-row SUV with V2L standard; V2H requires aftermarket EVSE
The math overwhelmingly favors V2H for backup capacity -- but dedicated home batteries have advantages too.

| Always Available? | Only when EV is home | Yes, always | Yes, always |
Best of Both Worlds
Many NJ homeowners are pairing a small home battery (5-10 kWh) for always-on essential backup with V2H for extended outage protection. The battery handles brief outages and daily TOU shifting, while V2H provides multi-day resilience during nor'easters and hurricanes.
You need a specialized bidirectional EVSE -- a standard Level 2 charger only pushes power one direction (grid to car).
Current NJ regulatory landscape for bidirectional EV charging.
Active through June 30, 2026. Covers 30% of equipment and installation cost, up to $1,000 for residential. Applies to bidirectional chargers. Must be placed in service at your primary residence.
$250 rebate for Level 2 EVSE installation. Applies to bidirectional chargers that include Level 2 charging capability. Submit application through njcleanenergy.com with proof of purchase and installation.
PSE&G, JCP&L, and ACE all allow V2H systems that operate in island mode (disconnected from grid during discharge). A UL-listed automatic transfer switch is required. Your installer must pull an electrical permit from your municipality. No utility interconnection application is needed for island-mode V2H.
True V2G -- exporting EV power back to the utility grid for compensation -- is not yet approved for residential customers in NJ. However, the NJ BPU is actively developing V2G frameworks, and PSE&G has run pilot programs. When V2G launches, your V2H-capable hardware will likely be upgradeable via firmware. NJ's Virtual Power Plant programs may eventually include V2G participants.
NJ Virtual Power Plant GuideNJ averages 2-3 major power outage events per year from nor'easters, hurricanes, and severe thunderstorms. V2H provides multi-day resilience.
4.7 million NJ customers lost power. Some for 2+ weeks. A Ford F-150 Lightning could have powered essential loads for the entire outage period with solar recharging. Traditional home batteries would have been depleted within 12-24 hours.
Historic flooding across NJ knocked out power to 500,000+ homes for days. Sump pumps failed, basements flooded. V2H can keep sump pumps running indefinitely -- a single sump pump draws only 0.5-1 kW, meaning a 131 kWh EV battery could power it for 130+ hours continuously.
With solar panels, V2H backup is essentially unlimited in sunny weather. Solar charges the EV during the day, V2H powers the home at night. Even in cloudy NJ winter conditions, a 8 kW system produces enough to cover essential loads and partially recharge the EV, extending backup duration from days to weeks.
What you need before a V2H system can be installed at your NJ home.
Most V2H chargers require a 200A service panel. NJ homes built before 1990 often have 100A or 150A panels. A panel upgrade costs $2,000-$4,000 in NJ. This is eligible for IRA/HEAR rebates when available.
Bidirectional chargers need a dedicated 60A, 240V circuit from your main panel. This requires 6-gauge copper wiring and a double-pole 60A breaker. If your panel is full, your electrician may need to add a sub-panel.
Required by NJ electrical code (and all NJ utilities) to prevent dangerous backfeed to the grid during V2H operation. The Ford Charge Station Pro includes a transfer switch. Third-party systems require a separate ATS ($500-$1,500 installed).
NJ municipalities require an electrical permit for V2H installations. Your installer handles the application and inspection. Typical NJ permit cost is $75-$200. Processing time varies: 1-2 weeks for most municipalities.
V2H (Vehicle-to-Home) uses your electric vehicle's battery to power your house through a bidirectional charger. The charger converts DC power stored in the EV battery into AC power compatible with your home electrical system. A transfer switch isolates your home from the grid during backup operation. Think of your EV as a giant battery on wheels -- a Ford F-150 Lightning has 131 kWh, nearly 10x the capacity of a Tesla Powerwall (13.5 kWh).
Total V2H installation cost in NJ ranges from $2,500 to $10,000 depending on the vehicle and charger. Ford F-150 Lightning owners with Extended Range get the Charge Station Pro included -- installation with transfer switch runs $1,500-$3,000. Third-party bidirectional chargers like Wallbox Quasar 2 ($4,000-$5,000) plus installation ($1,500-$3,000) total $5,500-$8,000. The Section 30C EV charger tax credit covers up to $1,000 of equipment costs through June 30, 2026.
For backup power, V2H is significantly cheaper per kWh of storage. A Tesla Powerwall 3 costs about $12,000-$15,000 installed for 13.5 kWh. A Ford F-150 Lightning provides 131 kWh of backup capacity with a $1,500-$3,000 V2H installation cost -- that is $23-$46/kWh vs $890-$1,111/kWh for a Powerwall. The caveat: your EV must be home and charged when you need backup power. A dedicated home battery is always available.
Yes, and it is the ideal combination. During the day, solar panels charge your EV for free. In the evening when solar production drops and NJ TOU rates peak (4-7pm), V2H powers your home from the EV battery. During grid outages, solar can continue charging the EV while V2H powers the home, creating a self-sustaining loop. The Ford Charge Station Pro and GM PowerShift both support solar integration.
The Section 30C EV charger tax credit provides up to $1,000 for bidirectional charger equipment (active through June 30, 2026). NJ Charge Up provides a $250 rebate for Level 2 EVSE installation. NJ sales tax exemption applies to solar panels but not EV chargers. The federal 25D residential solar ITC expired December 31, 2025, so it provides $0 in 2026. ADI/SuSI solar incentives apply to the solar panel portion of a solar+V2H system.
NJ utilities (PSE&G, JCP&L, ACE) allow V2H systems that operate in island mode (disconnected from the grid during discharge). True V2G (vehicle-to-grid, exporting power back to the grid) is not yet approved for residential customers in NJ, though pilot programs are underway. V2H systems must have a UL-listed transfer switch to prevent backfeed. Your installer must file for an electrical permit with your municipality.
It depends on your EV battery size and home consumption. The average NJ home uses 30-35 kWh/day. A Ford F-150 Lightning Extended Range (131 kWh) can power a home for 3-4 days at full consumption, or up to 10 days powering only essential loads (refrigerator, lights, sump pump, Wi-Fi). A Hyundai Ioniq 5 (84 kWh) at essential loads lasts 2-3 days. If you have solar panels, they recharge the EV during the day, extending backup indefinitely during sunny weather.
V2L (Vehicle-to-Load) powers individual devices via an outlet on the vehicle -- no home integration required. V2H (Vehicle-to-Home) powers your entire home (or essential circuits) through a bidirectional charger with a transfer switch. V2G (Vehicle-to-Grid) exports power from your EV back to the utility grid for compensation -- this is not yet available for residential customers in NJ but is being piloted. Most V2H-capable vehicles also support V2L.
