Disconnect/Shut off converter when inverter is on

If you’re going to be flipping the converter on and off a lot, I’d opt for a switch. CB’s aren’t really designed to be flipped repeatedly.

Can’t you install a device that automatically switches between two input sources? If it senses input on input A (converter) it uses it otherwise it use input B (solar). I forget what it’s called just know they exist, as I have one on my MH that switches which source powers the tv receptacle.
