Had a tech come out today to the campground after we got set up after our arrival to Florida. Just what I thought, it was the inverter. He did some checks and the inverter even though it was isolated, it was not putting out the correct voltage. Said my batteries were also in need of replacement. told him about the boiling noise coming from them earlier. Must say, none of these findings came as a surprise. Going to order the new inverter tomorrow, go get new batteries and then install everything at one time. Thanks for all of the assistance from everyone. It was greatly appreciated.
