Can I use a Victron Isolation Transformer on the input side to prevent GFI's tripping while charging

@kevind1 @thomasinaz Sorry for the wait. Here are the photos and a wire diagram I put together real quick. Let me know if you have any questions that you would like clarified! I may have left something out of the diagram, so if anything looks weird I can double check for you. Kevin, you mentioned a long extension cord could be the issue. What length would be the maximum you would recommend for a 15amp cord to run trickle?
