Inverter AC or 5 star AC

[pkadam1007]

Dear Friends,
I am planning to buy Split AC for my masterbedroom with following specs:
Area: 245 sq. ft.
Floor: 1st (There are floors above my roof)
Sun facing: Yes
Usage: 1-2 hrs during day time & 7-8 hrs during night time.

I am confused whether should I go for Inverter AC or 5 star AC.

Also suggest which brand and model should I go for.

Thanks & Regds,
