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 panels for multiple reasons!
A prior poster questioned why I would run my panels in series when My batteries are in parallel. DOUBLE UGH!
Of course my batteries are in parallel, I said so in my first post when I said I was running dual group 27 Trojans! Triple UGH!
Completely obvious and totally irrelevant.
Its a camper for crying out loud not a cabin.
So you bought a top of the line MPPT charge controller for $250, for a camper, when you have two mismatched 120W panels no longer made, and a 50W panel. A PWM would have handled all of that, no problem, with no ill effects... run them all the panels parallel, tie them in whereever,either at the input side of the controller, or at another junction box. 10 ga wire panels to controller will handle all the amps.
