I have a 2018 Roadtrec Agile SS. It is powered by 2 lithium batteries (solar). The coach has two inverter switches. One of them stays on, even when in the off position. I have attempted to reset it by performing a number of steps (i.e., turning lithium batteries off, turning coach battery off, etc.) to no avail. And unfortunately it’s the kitchen bank. Any suggestions? Photos included. Thank you in advance.
