and btw, that connector is not a "solar" unique connector. It's a 4 pin towing light connector. I chose to use one because of the current capability, the durability, and of course the easy of mounting for my situation. The lid helps too.

If it's wired to the inverter it would be a 120VAC connector for a custom made extension cord, with the matching plug at one end and a std 15/20 amp cap at the other.

I would "suspect" that the P.O. used that odd-ball method of connecting to indicate that it was connected to the inverter


Same answer if it's connected to the "Converter", except for 12 VDC.

Best bet... get out the volt meter and find out what's on the pins. And shame on the dealer for not having a better answer.

BTW: That's a standard connector and matching plugs are easy to find. I think that they are also used as a trail light connector instead of a flat 4 connector.

Might this be a spare battery connector for extra run time on the inverter?

I used one of those to connect a battery charger to my battery before I got a new power converter. That way I didn't have to get under the bed mattress and open up the battery box to hook up the charger. Mine is mounted inside the trailer. Used 2 pins of the male plug with short leads on it to hook my charger to.
