Hello, my car is standing.Often a few weeks and I have a 70Ah AGM battery inside. I bought two solar set with charge controller once 70A and once 60A. I wanted to ask, is the charge controller too high with the 60A should I rather buy one with 20A and secondly you can install the system as described on the photo of the set? It is purely about charging the battery. You can adjust the charge controller how high the charge voltage is zb 14.4 volt max. ed to the 60A charging controllers and 20A charging controllers Thanks to everyone!
