Another question I would like input on is this one. Is there a preferred way to connect to house batteries. I have a gang of 4. Do I connect red lead of chg controller to positive terminal on one battery and the black lead of of charge controller on the neg term of same battery? Is this the same as the pos lead on pos term of 1 batt and neg lead on neg term of an entirely different battery of the 4. Will they all get charged up with either connection I do?
Thanks all again.
As long as all are in parallel they will charge just fine. Best to connect the positive and negative from the controller to opposite ends of the stack of batteries. Your main RV connection should be same.
Also depending on your RV configuration it is best to check that the chassis start battery will also be charged. Some do automatic and some don't. Easy fix if needed. Once solar is connected a few days check in the early afternoon on a sunny day that all batteries are 13.2+ volts.
