You don't need the funny switch to choose solar vs or with converter.
-You can use both at the same time, no issues
-Should you want no solar, you already have the switch on the array side of the controller
-For solar only, no converter (why ever that?), You can use the battery disconnect switch to isolate the battery from the converter. I don't know if the battery disconnect switch is downstream from where you will parallel the controller and converter outputs. If it is, then you need another way to turn off the converter (by turning off its 120v eg)
- If you just plug things into the inverter or an extension cord from it, then no need to turn off the converter. If you plug the shore power cord into the inverter or into an extension cord from the inverter (like we do) then you need a way to turn off the converter's 120v.
