How do I hookup 1 solar panel to trickle charge my 2 connected RV batteries?
I want to trickle charge my RV batteries (which are connected to each other) using one solar panel. If I hook it up to one of the batteries will that cause an imbalance in the charge between them? Or since they are connected, will it even out? Or do I need to connect it to both of them individually? Do I need to connect a charge controller between the battery/batteries and solar panel or will the built-in charge controller in the RV suffice? The solar panel does have a built-in blocking diode. I'm trying to learn all I can about solar power -- hope you can help me.
