Bundle of pv wires through and not sure what ones what.
Well had something i didnt think about until after i had run the wire. I got all this wire ran. Hardest part was the trench. Got to thinking . What wire is what . Im pretty sure that they make a like coax to map the electric wires . But i dont have that tool . Nor will need it . So i improvised . I had a 12 volt lithium drone battery i had used when lights go out and a 5 meter led strip. I red to one wire and black to the other. Went all the way to other side . And done the same just with the light until it lite up. Then i marked the + with red electrical tape . Ground with green. And - with the black. Will probably get some heat shrink wrap this will probably be a lot more secure on the wire than electrical tape.
