The 1000-watt Power Inverter, # WC3720 that you linked to is a modified sine wave inverter capable of up to 1000 watts continuous, 2500 surge. You will need to check your appliance for how many watts are required for operation. If the wattage is not listed, you can simply determine this number by multiplying the number of amps by the number of volts (amps x volts = watts). We can then best identify the needed size of a battery bank for operation. However, this type of unit is frequently in the 100-to-200-watt range. Which means you need a battery bank with at least 100-Amp Hours of usable energy to as much as 200 AH.
