Ok guys here is what I have, and what I want to do. I have two 120 watt panels running through a 10 year old PWM charge controller to a set of two group 27 deep cycle 12 volt Trojans.I also have the original 50 watt panel that came with the camper s...
I am a complete newb with solar panels. I just bought a camper that has an older 50 watt solar panel and 20 amp charge controller. The controller itself looks to be a quality unit and I think I will keep it for now. My question is in regards to the t...
Traveled 1200 miles to Pueblo Colorado to pick her up.2007 S&S Ponderosa 8.5FBSCCan't believe it. What a trip the wife and I had. Memories to last a lifetime no doubt. Its a rear bath rear fridge full booth dinette. It is in absolutely beautiful cond...

UGH! In my first post I said that I just bought a state of the art MPPT charge controller. So now I am supposed to trade it in on a 50 dollar PWM Chinese knockoff? ? ? ? ? I have also mentioned numerous times that I cannot match my two 120 watt panel...

I am after voltage. Higher voltage will push more amps into the batteries. Thus the MPPT controller.Lower line loss, and more voltage.Not sure why it matters that the batteries are in parallel.
