Inverter based ACs draw less current when the target temperature has been reached. For them to be effective, they have to MAINTAIN that target temperature and stay 'on', in that reduced current-drawing state.
If there's constant loadshedding and AC going on/off, room temperature goes high and the AC has to work again at max rating to bring the temperature down.
That's probable reason why shopkeeper asked him to power it via UPS, so that the power supply is constant.
I thought max rating for DC inverter AC is 4.6 Amps, where as for conventianal ACs its aroung 9-10 Amps. I didnt see any where on their specifications page on their web site or user manual where it said max rating is more.
So by that logic even if its operating on max rating it should only use 4.6 Amps @ Max speed for 1.5 tons AC.
BTW Haier claims it their AC takes only 1 minute to cool temprature of room down, a claim which i believe since i have used other Haier ACs

Any A/C whether standard or Inverter type will only start saving after the set point temperature has reached. Standard type will initiate an ON/OFF Cycle of the compressor and Inverter type will reduce compressor RPM.
IMO the inverter type will cost you more in electric power bills because to achieve the set point temperature quickly, it runs the compressor at higher RPM resulting in more energy consumption initially.
In current power outages scenario, this will happen again and again resulting more energy bills.
conventianal ACs run the compressor @ full speed all the time where as DC inverter only for short time to bring room temprature down. According to Haier website it takes only 1 minute to cool down the room so i dont know how it can consume more electricity?
BTW my current AC keeps running the compressor for full 1 hour @ full speed during loadsheeding, & it consumes around 9.9 running current, if DC inverter uses 4.5 doesnt that cut the electricity bill by half?

i think you guys missed my point..
the AC is designed to run in uninterrupted power conditions.. even OP mentioned that generator or UPS is must..
Thus using UPS, you could run the ac for longer duration on lower rpm, and lower currents. thus energy savings
Even on UPS, the inverter ac consume a lot less than standard ac.. that is why they CAN be run on home use ups while standard would need atleast a 3500watt + semi commercial ups..
it doesnt say on the website that you need a generator or UPS. That would actually increase cost of runinng my AC which i am trying to reduce. If this AC consumes low power on UPS then why doesnt it do the same when connected to mains?? This new type could consume low Amperage even at high RPM.
Newer ACs have better features like better temprature control. my old window AC used to cool the room so much at night time that i needed a blanket even during summers thus wasting electricity.
BTW i do get 230 V 50 Hz in main supply so that is not an issue.
