The advantage of the MC4 connector is that it is waterproof and impervious to corrosion, which the cigarette lighter plug will not be. Since you have a removable panel you will be disconnecting and storing below, why not use the MC4 pigtail and leave the end of the wiring inside the cockpit lazarette? That way you can run the wire from the panel into the lazarette and have a connection not exposed to the elements, and avoid drilling any more holes in the boat.

I have never seen these before and am not sure what to do with them. I had planned on mounting a 12V receptacle (cigarette lighter type) in the cockpit to run wire through to the charge controller. Now I am not sure what to do. I guess I can remove or cut the MC4 and wire the ends to a 12V plug, but I am wondering if there is some kind of MC4 connector I should look for.
