This is a Georgetown with residential fridge.
From previous thread discussions, there is a dedicated inverter that ONLY goes to the fridge and no where else. That inverter has a "pass through" function that passes 120 VAC when available to the fridge. It is sized to drive the fridge only and trying to utilize it for other purposes may compromise the power available for the fridge.
There is also a dedicated battery for that inverter in addition to the coach battery(s); though all are charged by the converter.
That inverter is not available (as initially installed) to power any other AC items in the coach. In order to use the other AC items, you must start the generator or plug into shore power.
You can add another inverter to the coach batteries and run new circuits so that you can use them to run your 120 volt AC TV, etc. You most likely will not have enough battery bank to run high draw AC items like your microwave or air conditioner, so running the genset to use those items would still be required.
