Resurrecting my own old thread, now that I’m finally ready to hook up some rooftop solar two example controller: I assume the yellow is positive, green is negative? Not really sure exactly how to test that, even with a multi meter. Not sure if maybe if I have it hooked up correctly it will read positive voltage, if I have it backwards it will read negative?
Kind of weird how the wires are red and black at the rooftop solar port, but green and yellow at the under bed location.
