Your inverter is dead. Replace with at least a 2000 and stick with the Xantrex brand. The wiring is very specific and life will be easier to install the new one if you stay with Xantrex. I have a 2018 Hurricane (Love It), yet my inverter has died twice. That is not to say Xantrex is a bad name, mine probably died from over heat in the Southern NV summers. I leave mine on all the time, and machine plugged in. The Xantrex has an internal switch, thus power switches internally depending on Shore, House or Genie.
Best of luck and happy travels. The control panel is also just unplug from new unit and install in place of old control panel. Already wired for it.
