Hello everyone, I'm here for the same reason you all are! My first question to those who might know! There are two 50 amp Anderson plugs on the A frame hitch of my HQ15, one is black, one is gray. One is for a truck connection to charge the batteries and one is for a portable solar panel connect! Which is which!???? The Anderson plug at the solar charge controller is gray, so my best guess is the gray is for a solar panel???
