Question on transfer switch with inverter and generator

While away from home, you could just leave everything like MW,kettle, toaster,etc (fridge and WH on gas though, and-no air cond.) on inverter except the converter. When shore power or gen available that will run the converter, which in turn backs up the batteries doing the inverter and the other 12v stuff.

That's what we do. At home it is different, we do the manual transfer off the inverter to shore power (house) till next time out.
