Bidirectional power: what the Fathom can and cannot do
Ford has confirmed bidirectional power capability on the Fathom, and stopped there. Nearly everything people assume that phrase means is unannounced — so this guide separates the confirmed capability from the specifications nobody has.
The three things "bidirectional" can mean
- Vehicle-to-load (V2L): the truck powers tools or appliances through its own outlets. The simplest form, and the one most vehicles with this capability actually support.
- Vehicle-to-home (V2H): the truck backs up your house during an outage. This needs a transfer switch and usually utility approval — it is an electrical project, not an accessory.
- Vehicle-to-grid (V2G): the truck sells power back to the utility. Rare, heavily dependent on your utility, and not something to plan around.
Ford has confirmed only the general capability. Which of these three the Fathom supports has not been stated.
What has not been announced
All of the specifications that would let you plan anything:
- Output in kilowatts — unknown
- How many outlets, and of what type — unknown
- Whether home backup requires specific hardware — unknown
- How long it could run a house — Ford declined to say when asked
Any site quoting you a wattage figure or an outlet count for the Fathom is inventing it. This is one of the clearest cases on the whole truck where the gap between what is confirmed and what is published is being filled with guesses.
What Ford offers today, and what changed
This is worth knowing because it is recent and widely reported wrong. Ford's Home Integration System — the $3,895 Sunrun-installed package that enabled home backup on the F-150 Lightning — is no longer sold, and Ford has ended support for it.
Ford now points owners toward GenerLink, a meter-mounted transfer switch that runs about $1,100 including the vehicle connector, plus installation. It mounts behind the electric meter rather than requiring panel rewiring, though your utility has to permit it.
Whether either path will support the Fathom has not been announced by anyone.
What you can buy now
Nothing Fathom-specific, and we would not sell you anything that claims to be. What does work today is gear that is useful regardless of what the truck turns out to support: a portable power station covers jobsite and outage use with no vehicle dependency at all, and heavy-gauge cords and weatherproof outlets are needed for any power-export setup.
If you are buying a power station, one thing genuinely worth checking is UL 2743 certification. This category is full of careful wording — "meets UL standards", "UL-listed components" — that is not the same as the product being listed. We mark that distinction on every product.
Common questions
Can the Ford Fathom power your house?
Ford has confirmed the Fathom supports bidirectional power, but has not announced whether that includes home backup, how much power it can deliver, or what hardware would be required. Ford declined to say how long it could run a home when asked at the announcement.
How many watts can the Ford Fathom output?
Ford has not published an output figure. Any specific wattage you see quoted for the Fathom is not sourced from Ford.
What is the difference between V2L and V2H?
Vehicle-to-load (V2L) powers tools and appliances directly from the vehicle's outlets. Vehicle-to-home (V2H) backs up your house during an outage, which requires a transfer switch and usually utility approval. V2L is a feature; V2H is an electrical project.
Is Ford's Home Integration System still available?
No. The $3,895 Home Integration System is no longer sold and Ford has ended support for it. Ford now directs owners to GenerLink, a meter-mounted transfer switch costing around $1,100 plus installation. Whether either supports the Fathom has not been announced.
