Strange power problems with PI EMS 30 and autoformer?

Update...
After several days at home on 30amp each unit works fine independently. They also work fine together. Only had about a max. of 7 amp load on system but never had a fault code and never saw autoformer go into boost. Obviously, my home 30 amp isn't facing the draw that a campground would, but I have to believe that my problems were "pedestal" related.
We'll find out more next time out at a different campground.
