Hi all, I have a solar aerator system and a question on connectors that I've never used before (being completely new to solar by the way).

How in the world does positive go to negative in the same connection? I've never seen this before in any standard electrical wiring. Positive goes to positive, as in red to red normally, and same deal with negative (normally black) obviously.

Yet, the physical construction of the cable ends from the solar panel allows only for a negative to plug into a positive receptacle, and a positive to join a negative from a controller.

I look forward to learning more, and am trying to do as many online searches as I can think of to learn about solar wiring.

Thanks everyone!
Chuck
