Just posted - voltage dropped overnight from 14.1 to 12.8. Nothing is running except for the stereo on standby, which doesn't seem to be able to turn completely off.

Could this overcharging with shore connected then draining be a result of no solar controller, assuming there wasn't one installed. If so, I'd like to have some response when I call the dealer if they tell me that in fact they did not install a solar controller but try and tell me it wasn't necessary because the Xantrex served that function. From what I've read and been told, it does not.
