The specs on the refrigerator say at 110 volts it draws max 8.8 amps.
why are you calculating $ per year.
To convert to wattage you must take Voltgae (E) and multipy it by amp (I) and that number is wattage (W).
This is called OHMs Law.
So if you have as the spec show 110 volt AC times 8.8 amps = 968 watts of power.
I am only showing that the 1,000 watt DC to AC convertor has no extra output.
