Xanrex Inverter/Charger Over Charging
We had a solar panel and inverter installed when we bought our Jayco Whitehawk TT as well as converting the 12 volt to two six volt batteries. Expensive ones. The first time we used the inverter whil...

The converter is not connected to the solar panel as such. They are in parallel at the fuse panel. Turning on the converter should charge those batteries.
It will not overcharge them. The solar panel will when it gets the battery voltage above 15v, which will take a long time with those batteries so low and it being only a 150w panel lying flat in the winter's low sun. When you get to 15v or so leave it like that for a couple hours since the batts will need an overcharge anyway from being low so long.
Being under cover at the dealer's before meant no solar, so they didn't see any overcharge. You want a controller between the panel and the batteries, close to the batteries is ideal. IMO don't let them put the controller between the solar panel and the fuse panel since the wires from the fuse panel to the batteries are probably quite long.
TT's are the worst for that with the batts outside and you want the controller close but not outside. Some have drilled a hole in the floor up front to bring the wires from the tongue back and up to a front compartment where the controller would go. Now you need a route from the roof down to that compartment for the panel to controller wires. Depends on the RV what can be done that is out of sight.
Make sure they install a 30 amp or more size controller. (Those guys sound like they would try to give you a 5 amp one! ) You said you wanted to add a panel or two so start now with a controller that will handle your expanded array.
