So the question now that we are here.
existing set up is two group 31 agm batteries, all led lighting, 2015 fifth wheel with modern stuff. Panel is also unplugged at sunset and secured for theft prevention.
I have been running a small 65 watt solar panel when boondocking. the panel has a 25 foot cord that plugs into the typical power port installed at the battery location. I place the panel in the sunlight and move it along as the day goes on. I have never had an issue with over charging as there is always a draw on the system, pump light, lp detector, fridge, fridge fan, on and off pump, on and off radio and the use of a small 400 watt inverter for charging puters, phones, toys etc. I am upgrading to a 100 watt panel. why would i need a solar controller if i have a continuous draw on the battery bank? thoughts, ideas, tell me i am crazy etc. thanks in advance. Good Luck & Be Safe!!!
