Before I spend a lot of $, what do you think?
just using the Lightning PPO as a power source for Whole House backup With reduced loads.
Wiring the Ford Charge Station Pro, through a 30 or 50 amp CB, after the meter, to charge the Lightning.
Then continuing the meter line to an Automatic Switching panel with a generator input.
My home alarm company lets me know when power is lost. The auto transfer switches would then switch to Generator. I then activate the PPO to power the main panel.
When power grid power is restored it recharges the Lightning via the Charge
Station Pro.
Not perfect, but a lot simpler and less expensive than other methods.

If you are going to allow the FCSP to run up to your truck's limit of 48 amps, then you need a 60 amp breaker and wire size to match (6AWG Copper as I recall).

Then continuing the meter line to an Automatic Switching panel with a generator input.
Make sure your ATS also switches the neutral or else you will get the GFCI tripping in the truck.

Not sure what is simpler of less expensive about that, unless you are comparing it to the Ford HIS system, then yes indeed!

Seems like what you are doing, if I follow it correctly, is powering your house emergency circuits in an outage with the PPOB through a transfer switch, an automatic one that switches neutrals.

The only thing I wonder is will the switch work if the PPOB isn't already on? Some won't switch until generator power is detected which means the PPOB in your case. My manual transfer switch is that way.

And you are also powering your EVSE - the FCSP - with your utility power when available, also fine.

One thing I have noticed at my house:

When the PPOB is powering my emergency circuits, and the FCSP is connected to the truck at the same time, and utility power is available for the FCSP, the truck draws utility power at the same time it is providing PPOB power. I didn't expect that.

I noticed that when I was trying to draw down the SOC of the truck after an update had caused the truck to charge to 100%. I still had the FCSP connected not realizing that would happen.

When I saw the FCSP was powering the truck, I unplugged it from the truck charge port and the PPOB threw a 'ground fault' and shut off. The truck also shut off. Weird. Didn't expect that either.

I was able to turn the truck back on and restart/reset the PPOB and continue drawing down the SOC of the truck.
