Hi
Due to recently finding out that my MPPT controller isnt fully utilizing the 550W of solar panels, I have contemplated wiring my (4) 6V golf cart batteries as 24V to alleviate the problem. And this is under the assumption that my batteries will charge faster under the same sunny conditions. I will have to use a DC/DC convertor to step the 24V back down to 12V going into my RV. So that leads me to new questions.
Will stepping a more efficient voltage of 24V back down to 12V going into the RV make any difference as far as performance in lighting or appliances? That is, compared with my original set up of 12V battery configuration? The main reason I want to know this is because when I plug my camper into 110V 30A grid power, the lights and everything get super bright. The fans even run better. But not near as well just running off the batteries. When I added the last 2 batteries, I saw no increase in performance. So I supposed it was because of using 12V vs 24V. Obviously I cannot change the fact that the camper uses 12V for everything. But will configuring the batteries as 24V, then stepping back down to 12V still give the lights at least a slight increase in performance?
