I have installed a solar power system for an off grid system. I completed this project around a year ago. I check the batteries every month or so for maintance purposes. I noticed that under the bright sun my charge controller was sleeping. I found the problem was one of the cables had corroded/disconnected to the point where it disconnected all incoming power to the charge controller. It had a black residue on it that I could wipe off with my fingers....Mold? Ash? I attached two photos of the pin that was removed from the Anderson connector.
How did this happen?
Couple points to consider:
The system is a portable system that is based on a trailer.
The trailer has just under 1200watts of solar panels.
The panels are run in series at about 120vdc.
Due to its mobile purpose I use Andersen plugs as quick disconnects that are exposed to the elements.
The circuit breaker did not trip.
The lead that was corroded was the positive lead.
