On Road need help with inverter

[Rhoadzie]

I've spent the last week down in Florida with my 27rr. On the way down we dry camped in a Walmart lot, no problems. Got to the park and the power chord was too short, no problem. Everything ran all night until I could get an extension chord. Hooked up to power all week no problem. Went to leave and inverter will not run the Refrigerator. It has an E04 message. It acts like the batteries are low, but everything works off the batteries with no problem and they show fully charged. Any help on what I can do on the road to get it going?

If you have a Xantrex E04 is a high temp code. Make sure nothing is blocking the rear vent of the inverter
