Still a newbie trying to figure things out...
I purchased an Eco Delta and the MC4 charging cable that came with it has a positive male connector on the black wire and a negative female connector on the red wire. When I go search to find an adapter cable, the cables online all seem to have positive red wire connectors and negative black wire connectors. What is up with that? Why isn't there some standard ie. all red cables are positive?
I wanted to buy a few Rich Solar panels for my Eco, but their polarities on their panels are the opposite. What am I missing here?
