Interesting conversation….
I should have to double check to see that I do not have them going to the battery. I think I have it all through the SunSaver Morningstar 20A controller. It is not one of those $14 ebay specials.
My batteries were only in the truck bed before, so to load I had to rely on the converter to lift it, I could not tell the difference. If the converter was weak i should hear a difference in the motors compared to batteries. No worries, the new will have a battery back in the camper.
I will hook directly to the batteries and use the charger just for solar connection.
