Hi,
Shore power--->breaker panel--->items to be powered
Generator with transfer switch feeding the shore power cord. That will default to inverter when the generator is off.
I often use my inverter when on modest shore power and also when drawing heavy loads from the generator. For example the generator can't quite power the air conditioner and the electric water heater at the same time. But it can power the air conditioner and the converter. The converter sends power to the batteries and the batteries power the inverter which powers the water heater.
gen-->shore power cord-->loads (air, fridge and converter)-->battery bank-->inverter-->water heater.
I also have a dedicated inverter outlet in the kitchen which I use almost every day that I cook.
