    Your RV has 2 distinct electrical systems; 12vdc (just like your car) which includes lights, water pump, furnace, fridge control board...and 120VAC (just like your house) which includes the microwave, air conditioner, TV (depending on model), outlets. Your battery bank provides the 12vdc, and shore power or generator provides the 120VAC.

    A converter takes 120VAC (from shore or generator) and converts it down to 12vdc; think of it as a battery charger + dc power supply.

    An inverter takes 12vdc from your battery(s) and converts it up to 120VAC; think of it as a small battery powered generator. It allows the use of small 120VAC items without shore power or generator.
  • Inverters draw current themselves and are limited in what 110volt AC stuff they can operate without running your 12 volt DC house battery down. They will operate low current draw items like CD players, but are not miracle devices.
  • Coach batteries same as house batteries

    Engine and chassis battery same thing.
  • An inverter (depending) on size can run any 120 volt light, TV, appliances from your 12 volt batteries. I have ran microwave, coffee pot, electric razor, TVs, etc. All depends on inverter and battery capacity and out put. You do not have to be underway to utilize the inverter or converter. The inverter is good for when shorepower is not available. The converter is necessary to run your 12 volt lights, refrigerator control panel, etc whilst connected to shorepower.
    This is a brief description.

    ??? charge 12 coach batteries ??

    rvten didn't proof read his post. ;)
  • Converter takes the 120V AC power from your generator or shore pole power and converts it to 12 V DC to charge your battery and provide 12V DC power to the coach systems like the water pump, lights, etc.

    Inverter takes the 12V DC power from your battery and converts it to 120V AC power. Can be used while underway to power low power devices like your TV.
