Solar wiring question
Looking to install solar on my prowler 24lz trailer. Watching and reading peoples installations it seems that the best thing is to install your charge controller near your battery and then wire direct...

Yes that warning came from the manual for an ASC controller I had which was a shunt type.
I did have some problems with some wiring schemes I was trying out with my series type PWM where I had some converter going through the controller because I got things mixed up. It just didn't work. Speculation was because that particular controller was meant to be positive grounded if the installation required it to be grounded.
Once I got things all the right way around with controller and converter in parallel it was fine.

Is there a way to tell if they are cu or al with those MC4 cables without cutting them?
I have been looking at Home Depot's well pump wire which is amazingly low cost. You get four wires twisted together with each wire being stranded copper #12. I am thinking you could parallel two each for pos and neg and get a set of #9s in effect, which would be good with the long 24v run from array to controller. Haven't decided yet
