    You need to convert the running amps x hours used divided by 1000 into kWH (KiloWattHours). This is how the electricity companies charge.

    The way to do it is to measure your average running current (difficult on inverter splits) and multiply it by the voltage. This will give you Watts. Then multiply the Watts by the average running hours/day. This will give you KiloWattHours (kWh).

    Then multiply this by the unit rate you are paying for the electricity.

    Example:

    4.2A x 240v = 1008W
    1008W x 8hours/day /1000= 8.064kWh/day

    8.064 x £0.21 = £1.69/day

    Just substitute £ for Euros or $
