- We did some cool testing with a Ford Lightning while installing a solar system.
Let's discuss your solar goals:

Make sure the Sol-Ark was limited to 30A for the generator setting, and pull the ground plug on the cord going into the 14-30 on the truck side. The Lightning will fault due to GFCI and how the Sol-Ark is grounded if you have it hooked up without disconnecting the ground plug.
It's unfortunate that vehicle manufactures are blocking V2G implementations for those who already have inverter set ups, hopefully Ford and others comes to their senses and opens up their API so Sol-Ark and others can use it via the CCS plug like it should be.
I was just coming to say the same thing, you cant connect grounds.
Yup. That's how I connected my lightning.
I also put in an auto transfer switch to run a sub panel. That works since the lightning does not see a neutral ground bond.
Always good to see helpful comments. Thanks!
What's the Lightnings Max output when using it to back up some circuits? I'm sure it can't back up a whole house or can it?
I believe the Truck has GFCI protected circuits. Because you have a neutral ground bond downstream in the circuit somewhere, it will see a ground fault A simply fix is to remove the ground from the cable coming from the truck. You will still have your house ground in place.
As others have said. The generator inlet box needs to leave the ground off. The truck is neutral bonded and the home is also neutral bonded. I left the neutral disconnected and mine runs my home well. No issues.
Really cool video. Would have loved to have seen it charging up the batteries.
Scott, another great install. I can imagining you singing "I got the Power"....Cheers, Mate.
Remove the ground from the panel to the reliance. The lightning has an internal neutral-ground bond and the combination of that and the one in your main panel is making the Lightning’s GFCI trip.
Thanks Scott. Another neatly done job.
Seeing through all the holes. The mark of posts well set.
great work
Awesome. If you could please share your experience with the rest of us that would obviously be very helpful and much appreciated.
With the huge quote from sunrun, for V2H, we just built an offgrid system of 3.6kW panels, 10kw bank, with an EG4 6000ex-48HV for offgrid charging the lightning through the Ford Chargeststion Pro. We’ll use extension cords, or do a subpanel with transfer switch if it ever seems like we’re missing it. We can only charge at 12-16 amps, but it’ll have a 4-5 year payoff, so I think we’ll be good with free fuel in 5 years. We may bump up to 20kw of batteries this summer when the panels are producing that much.
Pytes makes two kinds of brackets. You have the F. & B. Bracket kit there. They also make an R-Bracket single and 8 version. The 8 version is the same as the single just packaged as a group. The R-Bracket is a lot stronger than the F&B. I also recommend mounting either bracket style on a riser, like a box made from 2x6, etc. that’ll keep the dirt, water or other debris away from the bottom battery.
busy boy i have solar wind project coming this spring
The issue probably lies in the neutral/ground binding location. Might need to pull the neutral out of the system.
This is something I am so interested in. Please investigate further.
I’m currently topping off our new Envy 12k’s and (4) evaults with our Lightning. It’s awesome.
Awesome. If you could please share your experience with the rest of us that would obviously be very helpful and much appreciated.
I set the gen input to 5kW and run from the 240v plug to a disconnect, then into the gen inputs of the fortress Envy’s.

Thanks for posting the video Jeff. That's one helluva system you have installed!
Any serious Off grider would be proud to have done that. Kudos.
Do building codes ever require Intumescent paint on the plywood in the electrical room?
Maybe lower the charge rate or amps on solark? Down to minimum then work up?
I think to get the best vehicle to home connection, you may need to use Ford's two-way charge connector so you can pull power directly from the DC charge plug.
I hooked up my son’s 2020 Ford hybrid truck to a changeover in his garage. No batteries or solar involved but the truck kept tripping its breaker even when there was no or minimal load. Found out it was tripping on a ground fault. Disconnected the ground through the umbilical cable and no more trips. Ran their house fine less A/C units. The truck would automatically start when the batteries discharged to a certain level and then turn off. I would bet that is the problem you are seeing.
That's hybrid, it's not the same
I am also currently working on getting my car to charge the batteries as an emergency backup. Hopefully Sol-Ark will have some ideas, information and instructions on how to do it safely.
Is there any major component on a second-generation Prius that could be implemented in creating a mobile generator setup for using power tools? I have two sitting on a lot with dead hybrid batteries and want to know if there is anything useful beyond its scrap value still in there.
That stack of batteries was how much compared to the $300 rack to hold them? (I'd probably be looking for a cheaper rack option myself 😂, like just some unistrut to hold them off the floor and together and to the wall so no chance of tipping over.)
Are you limiting the pull on the gen to 7.2 KW?
40amp limit.
I want to do the CCS output so it can directly tap the 400V battery of the Lightning.
Which is better for Off Grid car if you want to minimize your reliance on outside supplies, EV or Wood Gas?
I know ethanol and biodiesel wont work, they need too much material and energy to farm and process and are therefore energy negative.
My Prius does some stupid tricks.
current limiting on your inverters charge circuit would do the trick - maybe there is a parameter for that.
Ground neutral bond?
Did you try reduce the generator input to something little that the Lightning would obvisouly handle? 500w or something like that?
Ford website says something about Ford Charge station Pro, so maybe you need to connect thru that, for electrical safety / liability reasons maybe.
Disconnect the ground pin and the lightning won’t trip
I think you need to buy tge interfacing attachment to do vehicle to grid. You cannot getvit charging the batteries without it.
I think it's called Ford charge pro, home integration system..
Might have to use a dummy load like a light bulb or hair dryer connected in parallel. That way the truck sees a power consumer and you don't have two systems trying to be smart, waiting for each other and never starting.
Its the same with a smart 12V battery charger and a dead battery, first you have to turn it on supply to make the battery take 12V before it can start charging normally.
Yeah, that Ford lightning for feeding into things is really useless because of the ground fault protection within the vehicle
If Ford can fix the issue that they know about where they want you to cut the grounding conductor, which is absolutely absurd.
Hook it up to a chargeverter instead
I would NEVER connect my EV to a high frequency, transformerless inverter. There's no galvanic isolation between the battery and the AC output! All it would take would be for the AC output monitoring circuitry to fail and a MOSFET in the H-Bridge to short to ground and you'll smoke your EVs on board charger.
I don't even know the language spoken in this video and comments! Lol
