An update on the Xantrex 458...took our rig to ONE STOP CUSTOM SHOP
in Colorado Springs and the owner, Robert, was THE BEST! He replaced the AC board in the unit in about 2 hours for around $800.
The first thing he noticed when we pulled in and he looked at our battery bank was the cables were hooked up incorrectly to charge 3 batteries. We were basically charging one battery and drawing off one battery. Luckily we didn't ruin them in the last 3 years. After he rewired the bank, we went from having a charge for only a few hours to not having to run the gen for 15 hours! Woot Woot!
If it weren't so hot here we wouldn't have to run the gen but I NEED my AC
We will be going back to his shop in August to have solar installed and we will be totally self-sufficient
Thanks to everyone who helped me through this whole ordeal.
This is the BEST rv website I have been on and the most helpful
