I just checked mine and it IS reverse polarity. I would not have thought that. It makes sense to have it that way so the female portion of the plug on the solar panel does not short against something when not plugged in. I checked one of my tenders and the hot side (male) does not turn on until it is plugged into a battery so I guess not to short against something before IT is plugged in. On my motorcycles, the female part of the plug is hot and the male portion is negative.
