Nothing else needed - Just use the circuit breaker on the Power Distribution Panels to control the converter/charger unit. The shore power will run all the things connected to the 120VAC side the solar panels will keep the battery bank topped off to run everything on the 12VDC side.
If you have a low wattage Power Inverter setup for HDTV and a few other low wattage 120VAc items then the Solar Panels will be used for that as well by keeping your battery bank topped off.
Just think of the solar panels as a battery charger...
