Panel to Solar Controller Wire Size
As some of you already know, I'm piecing together a solar system. Controller is a Morningstar 45A PWM. Panels will be two 12V 150W wired in parallel. I'm going to be using a combiner box on the roof, ...

PT, usually the story is that the panel heating hurts MPPT more from the voltage drop whereas PWM doesn't care much about voltage drop and anyway, Isc goes up with heat. MPPT doesn't care about Isc, it uses voltage.
