There is a white button in the breaker box. I don’t have a dog bone. Only a 50 amp surge protector. It seems my inverter is not recognizing the shore power. So the solar and the batteries are getting drained because I’m using the trailer like I’m on shore. For some reason I have to unplug the power cord to get the outlets to work again. I woke up to the trailer absolutely lifeless this morning with no electricity. While plugged into shore!! I changed the cord but I’ve turned off anything I’m not using. I’m going to get a tech to come in and look at my system. I don’t think the dealer installed it correctly.
