You can install a contactor relay switch. The power wires going to your converter/charger would connect to the "Normally Closed" input on the contactor then continue connect from the "NC" output to the converter. Your inverter output wires would connect to the Normally Open terminals so the converter line will always be active until you turn on the inverter, at which time the converter line will be disabled.
