I'm new to all of this battery info; just bought a Class A RV and am trying to get the power setup so I can boondock for a few days and then travel on without worrying about the power system of the RV (minus the Air Conditioner). Trying to understand some basic assumptions so I can make the right decisions about what pieces of equipment I should buy that will all work in harmony? Right now I have 2 105 Ah batts with a smart converter/charger @55 amps; I want to add a DC2DC charger (40 amps?) to charge from the alternator (130amps) to use while driving. I plan on adding solar and adding 2 more 105 Ah batteries, 420 Ah total; the confusion is what do I need to buy to keep these batteries charged with the minimal amount of time required. From everything I read too much info is provided confusing the basic questions. For solar I was looking at 2 panels that are 320 watts each (640 watts parallel) with a 150/60 MPPT controller and at some point adding a 3000 watt inverter to manage all AC requirements while boon docking (minus AC); so with all sources connected to the batteries providing power I do not understand what will be the interaction between all of these devices providing a charge. On some threads it appears they will just act independently, on others they say one will take control, on others they suggest it could destroy the batteries with overcharging...I don't work with this stuff everyday and its overwhelming...just looking for some help
