What is your main point to be buy Aircon?
Wanna cold down your room temperature right.
Power consumption wise from inverter input watt was : 800@ 2.6kw meant = 8870 btu for standard factory setting, but you can range from 1.1kw to 3.0kw meant you can set from adjust your temperature from minimum set at 27C to 22C in between grap of DC computer would tell the signal to range from low mid high compressor running speed, but you also can set as 25C for normal standard size on 3x3m there is cooling quite comfort already.
Inverter had built-in both side temperature measure to tell the PCB for increse / decrese outdoor compass or running in JET speed from daytime in hot weather.
Once going to night of the outdoor compressor & fan speed would reduce a lot of waste energy n heat an issue.
Why for the non inverter outdoor can hear noisy and the whinning/humming sound used within a year or 1 year plus.
http://www.repairclinic.com/RepairHelp/How...s-loud-or-noisyCause due to non-inverter Aircon still using AC compressor today and high input watt for fixed speed an never runs in low speed, but there only run in high speed for quicky cut down the room temperature to save cost.
Meant : for non-inverter really good to used in daytime of runing in same speed in the room and never cut off when the room temperature are reached.
Once in the night time there is can't adjusted of same comfort temperature and 26C above, you would realise there is works like on & off of whole unit suddenly stop run and feel like no current or backup and keep for 15mins ago to be start run again until next morning.
If you are the death sleep maybe never feel that thing happen, if you are the sensitive person, I think you would cry for this.
That is nothing to be compare from inverter or non inverter today,as you can pay for extra amount on inverter then go with it and you won't getting regret answer here.
Long run n comfort for sleep is your correct answer
thanks for the explanation!for the long run it is way better to opt for inverter?i'm planning to install 2x1.0hp n 1x2.0hp of ME. Any recommended models?
