Charging while also using Pro Power Onboard

[Maquis]

Not sure, I need to look into it more, but I was surprised because my assumption was that the onboard charger and the ProPower would be isolated from each other. Maybe that's not the case.

There is only one “ground” on the truck (chassis). The ProPower EGC and the EVSE EGC end up connected together.

You may wanna buy the ford power backup solution… it’s expensive($4k equipment, maybe 4k labor to install), but it makes those things automated, and works

Are you talking about the Home Integration System (HIS)? I haven't seen anyone say that it works consistently or well. I think the best I've see is someone who can get it to work after hard rebooting it. Have you had a positive experience with it?

I can charge my truck via 240v 16 amp home charger (I assume I could have charged at higher amperage if I wanted to) while I was also charging my plug-in hybrid Volvo at 16 amp via the 240v bed plug with pro power onboard (this was a test).
When I unplugged the truck from my home charger (non Ford) the pro power onboard turned off, anybody know why (nowhere near any set limits)?
Pro power onboard resumed charging my Volvo once I turned the truck back on again (I never turned it off).

Likely just because the software is programmed to do it that way as Ford never thought of your use case. The PPOB turned off cause the truck did. Why did the truck turn off when you unplugged? Cause Ford didn't consider people would do what you're doing. Report to them via the feedback in the truck and maybe they'll fix it.

Tonight I did an interesting test, I wanted to power the house off my truck for the night since we are expecting storms around 3am and I didn’t want to have to flip over then if the power went out.

My garage is on a different meter and fed by a different pole, so I left it plugged in to charge off the FCSP while I hooked up the house via an interlock (which has worked great multiple times in the past). The truck kept giving a ground fault when both were plugged in and wouldn’t turn on the ProPower. Once I unplugged the FCSP, it worked perfectly. I then tried plugging it back in and it failed again.

Not that big of a deal since I charged up to 100% already, but was hoping I could just use the truck like a big UPS battery in times like these.

I suspect something isn’t right with either some hardware or your set up, or software. I have no problem using my truck as a giant storage battery back up, zero issues charging while supplying power, I can unplug and plug in without issue.
The only thing worth mentioning, is when I unplug the charging cable from the truck, the truck will go into accessory mode and that will automatically turn pro power off.

However, I can plug the charger into the truck, and pro-power will stay on. It’s only when unplugging the charging cable from the truck does pro power turn off and the truck go from on to accessory.

It’s been seamless.
