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, ...

You will not get Voc (23v) at max amps. Closer to Vmp (19.1v) to figure losses from regulating voltage.
Still plenty of voltage to practically ignor wire size from panels to controller.
