Here I have some formula to calculate of monthly usage 8 per/hr x 30days.
Non-inverter Aircon system 3, power input watt : 1.935kw x 8 x 30 = 464.4 X 0.25cent per/kw = $116.10
inverter system 3 power input watt : 1.9Kw of Part load equal to 70% saving = 0.63kw x 8 x 30 = 151.2kw X 0.25 = $37.80 per months can be up to $78.30 per/mths so much diff. From non-inverter for 8 hrs per days usage.

Last time I saw aircon ads in the newspaper, from non-inverter to inverter 4 ticks can save about $800/year.

So average can save $66.67 per month.
