Solar voltage drop calculations, new question
Using a calculator: I like this one When figuring wire size from panels to controller for "12v" panels in parallel and PWM controller, we should use 20v as our input, right??? I see writeups wher...

When you got 21v at the input side of the controller, was that with the battery side connected? ISTR I can only get Voc by disconnecting from the battery, but it's been a while since I last did any of that.
I thought with 12v PWM, panel voltage was the same as battery voltage and the controller limits how high that voltage can get.
