Fathom Bidirectional Power Overview
Fathom bidirectional power is meant to remove the wall-mounted inverter, a major cost in vehicle-to-home charging. Ford announced on October 27, 2026 a 2027 Fathom pickup built with the inverter inside the truck. According to Ford, it is the first EV from a U.S. automaker with an MSRP below $30,000 to send over a projected 10 kW of AC power to a home without a separate inverter.
An EV battery stores direct current, while a house runs on alternating current. Because of this gap, most bidirectional EVs need external conversion gear. Canary Media puts this equipment at nearly $7,000 to more than $10,000.
Ford says it rebuilt the system after buying the startup Auto Motive Power in 2023. Notably, Ford also expects the home hardware to cost far less. Ford targets about half the cost of its first-generation charger for the Home Power Station. Also, Ford targets at least 60 percent less than its first-generation backup hardware for the Home Backup Power Panel. Ford has not published prices for either.
For price, drivetrain and range context, see our Ford Fathom explainer. Our report on Fathom production timing covers the launch risk.
The Fathom arrives in 2027, so a portable power station is the outage backup you buy today. The Jackery Explorer 1000 v2 offers 1,070 watt-hours, while the EcoFlow DELTA 3 and the Anker SOLIX C1000 Gen 2 each offer 1,024 watt-hours. Output varies, so check each unit’s AC rating against the appliances you plan to run.

How Fathom Bidirectional Power Moves the Inverter Into the Truck
Ford placed the inverter in the E-box, one of five main modules in the Fathom. Instead of a box on your garage wall, the truck converts battery power to AC itself. Fewer parts mean a simpler and cheaper system, according to Ford. Specifically, Ford says the design is intended to meet UL 1741 requirements and comply with IEEE 1547 interconnection standards.
The truck also talks to the home equipment through SAE J3068, a communications standard Ford says was developed at the University of Delaware. Ford says this standard also lowers charger cost. University of Delaware professor Willett Kempton told Canary Media AC capability designed in from the start costs $200 to $300, while adding it later costs far more.
Two Ways Fathom Owners Will Use It
Home Power Management lets you charge the battery when electricity costs less, then power the house when rates climb. Ford says it requires Ford’s home charger, utility approval and an active Ford trial or plan.
Home Backup Power sends energy to the house during an outage. Ford calls it a clean, quiet alternative to natural gas or diesel generators. Specifically, you need the Home Backup Power Panel with Ford’s home charger, and Ford says the setup needs utility notice or approval in some cases.
Fathom Bidirectional Power Cost vs. F-150 Lightning, GM and Tesla
Ford published percentages, not prices. The table below pairs reported first-generation costs with Ford’s targets. The Fathom dollar figures are our math, not Ford’s, and none include installation.
| System | Reported or targeted home hardware cost |
|---|---|
| Ford Charge Station Pro (F-150 Lightning) | $1,300 for the charger; $5,200 with a home integration system. |
| Fathom Home Power Station | About half of $1,300, roughly $650 by our math. |
| Fathom station plus Home Backup Power Panel | At least 60 percent below $5,200, roughly $2,080 or less by our math. This is Canary Media’s reading; Ford applies the 60 percent to the panel against first-generation backup hardware, so the total runs nearer $2,210 on the other reading. |
| GM DCV2H bundle | $6,748 promotional price through Nov. 2, 2026; $8,998 list. |
| Other external-inverter systems | Nearly $7,000 to more than $10,000. |
Tesla also offers AC power to a home. Canary Media notes the Cybertruck has supported it for more than a year, and newer Model 3 and Model Y vehicles send AC power to homes with Tesla Powerwall batteries. However, the same report says the Fathom costs far less than Tesla’s EVs and needs no costly backup battery. The report gives no Tesla hardware price, so the table leaves Tesla out.
Ford’s all-electric pickup, which NPR reported Ford stopped building in December 2025, used the Charge Station Pro. Our Scout Terra vs. F-150 Lightning comparison covers the truck as a used or leftover-inventory buy.
What Ford Has Not Said Yet
The announcement does not state the Fathom’s battery capacity, so outage runtime stays unknown. Because a 10 kW rating describes how much power flows at once, it says nothing about how long the power lasts.
Prices are also targets. Ford has not finalized the exact cost of the home power management hardware, and installation costs vary by home.
Utility rules are the other gap. Canary Media reports only California and Maryland have set utility rules for AC bidirectional charging outside pilot projects. Most of the 3,000-plus U.S. and Canadian utilities have their own processes. Therefore, Ford formed a working group in July 2026 with American Electric Power, BC Hydro, Consumers Energy, Exelon and Pacific Gas and Electric.
One working-group principle matters for outage use. Ford says interconnection should not be required for customers who use their EV only for charging or isolated backup power. Instead, it should apply when a bidirectional EV runs in parallel with the grid.
What This Means for You
Price the whole system, not only the truck. The Fathom starts at $28,350 plus a $1,595 destination charge, but the home charger, backup panel, installation and utility steps add cost. Ask an electrician for a quote before you count on any savings. Ford has asked interested buyers to register for a preorder invite, so a place in line is the first decision, not a purchase.
Next, measure what you need to run. A plug-in watt meter shows what a fridge or router draws, and the P3 Kill A Watt P4400 reads volts, amps, watts and kilowatt-hours. Those numbers tell you how much backup any system has to deliver, Fathom or not.
Outages also call for basics no truck replaces. The Midland ER310 has a hand crank, charges by solar, and scans NOAA weather channels, while the Goal Zero Lighthouse 600 offers up to 600 lumens.

For me, the cost cut matters more than the 10 kW headline. At $5,200 for the full system, earlier gear priced vehicle-to-home charging out of reach for budget buyers. Cutting the cost roughly in half, if Ford delivers, lowers the barrier. I have used a Starlink Mini many times as a home backup when my home internet went down, and in my view a backup earns its price on the day the main system fails.
The announcement covers powering a home, not a campsite, and Ford has not said how the Fathom handles camp power. If camp power is your goal today, hood-mounted solar panels work now without a new truck.
Final Thoughts
Ford moved the inverter into the truck, so you skip the wall-mounted unit. If prices land near Ford’s targets, the Fathom puts home backup within reach of buyers who skipped it before.
Still, these are targets until Ford publishes battery size and final hardware prices. Your utility’s rules also decide how well it works. For now, treat the 10 kW figure as a projection, as Ford does.
If you plan to buy a Fathom for vehicle-to-home use, ask your utility about interconnection now and wait for Ford’s final prices. If you need backup this winter, a power station and a few basics cover the essentials. We will keep covering the Fathom while Ford shares more.
FAQ
What is Fathom bidirectional power?
It is Ford’s system for sending power from the Fathom’s battery back to a home. Because the inverter will sit inside the truck, Ford says you will not need a separate wall-mounted inverter.
How much power will the Fathom send to a home?
Ford projects over 10 kW of AC power. Because Ford has not published the battery capacity, runtime during an outage is unknown.
Does Fathom bidirectional power need an external inverter?
No. Ford says it built the inverter into the truck’s E-box. You still need Ford’s home charger, and the Home Backup Power Panel for outages.
How much will the home hardware cost?
Ford has not published prices. It expects the home charger to cost about half as much as its first-generation charger, and the backup panel at least 60 percent less than earlier backup hardware.
When does the Ford Fathom arrive?
Ford says the Fathom arrives in 2027, starting at $28,350 MSRP. Also, Ford has asked interested buyers to register for a preorder invite.
