I am not sure I follow the 320A service requirement, anyone know more about this?

The 320A is listed as a requirement on The F150 Lightning website. Means you'll probably need 400A service to your house - which sucks.

One of my coworkers (Electrical Engineer) thought I was crazy two years ago when I told him I planned to upgrade my 60a service (OLD house) to 400a. Who’s laughing now?! ?

Though I have never taken more than 150A from it my service is 400A. Though I have never taken even that much at my lake house they (the utility) made me put in 600. There are complicated rules relating the service size to the connected loads. These depend on the jurisdiction. EVSE are big loads. They have a big influence on required service.

Though I love EE (he's one of the few posting videos who really knows what he is talking about) there are a couple of things that require comment. He says he used 20 kWh/da!!! Is he a latter day Thoreau? The average American uses 30. I use 200 on an unusually cold winter day and 110 or so on a typical summer day (heat and cool with heat pumps) and no, I do not live in an Al Gore sized mansion. Thus neither a BEV nor a set of powerwalls is going to carry me for very long if I want heating or air conditioning. A gerator, expensive as it is to install and operate, is the only practical way to get through a 5 day power outage if you want all the amenities you are used to.

Another thing to think about in using a truck to back up your house is that when you are out and about in your truck it isn't there to back up your house.

And finally one should ask whether he wants to use a large portion of the finite number of charge/discharge cycles in his battery to back up his house. We have been assured that the "million mile battery" has so many cycles that this isn't something to worry about but the million mile battery isn't here yet.

I'm not seeing that anywhere. I am seeing that it's limited to 9.6kW peak export, which is no-where near 320A.

I believe it charges at nearly twice the typical 10 kW that is near 20 kW which is a bit less than 100 A. With the derating factor that's about 125A. Typical houses have 200A service. This would be in addition to that so 320A. But you need to sit down with an electrician to see exactly what will be required in your particular case.

And if the truck really is limited to 9.6kW peak export, It should be able to supply backup power to 100% of rated capacity on a 50A circuit. Obviously that's not ideal for charging if you have the dual onboard chargers, but there's no technical reason it couldn't work unless Ford doesn't let you restrict the unit down in power.

It can pull 80A or push 40 so it requires a 100A branch in a 400A panel.
