I recently purchased an RV with a solar setup installed and am having trouble diagnosing what needs to be upgraded in order to solve the problem ihaving.
I have 500W of panels on my roof, and my 2x200ah deep cycle gel batteries are charging up to 12.7v+ most days if my daytime electrical use is moderate to low. However, even trying to keep our electrical consumption low, our battery monitor has been showing that the battery charge is pulled down below 12.1v overnight even running just a couple of small 12v fans and led lights.
Generally speaking, in a situation like this, would you add more panels (and upgrade the charge controller etc etc) so that the batteries are receiving more charge during the day, or add another battery or two to the bank to increase capacity? Or are both absolutely necessary?
Here are the components of my current system:
3x100w panels, 1x 200w panel
50a renogy mppt dc-dc battery charger/charge controller
2x 200ah renogy deep cycle hybrid gel batteries
1x 3000w inverter
thank you!
