Solar MC4 connectors

Designing my portable solar for camping.

I cannot find MC4 connectors that are color coded red/black.


Am I complicating their usage?

Feel free to design and market this idea, just send me a box please:cool:

If connectors only in black, then Use colored wire, or make a label with tape.

I think mine had one of the black wires with a white stripe. Not as obvious as red/white but it worked and I didn't fry anything.

MC4 connectors are not really designed to be connected then disconnected a bunch of times. They are designed to be connected and left alone on a permanent, fixed solar power system.

Google Anderson connectors. You'll probably find something that better suites your needs.
