Bro, I am justifying the cost. Yes, inverter saves power from day 1, but it costs 1.5x to 2x of the normal split BEE 5 Star.
So, if you are using AC for less time. Say less than 6 hrs/day for 4 months in a year, still, you would be spending less on BEE 5 star than inverter even after 5 years of usage (including power charges).
I have done the analysis. Hope I was able to explain my point.
