That is true for a compressor that functions in a normal way. My LG non inverter, single speed compressor, window AC uses anywhere from 570 -660 watts depending on how hard it has to work based on the ambient temperature. Inverter ACs alter the frequency of the compressor from 10-120 Hz. It might be possible to trick the outdoor thermistor in order to keep the AC running at a lower, more efficient, frequency. Still, working at 10 Hz with a high ambient temperature would use more watts than working with a low ambient temperature at 10Hz. Before I bought the Midea, I expected inverter ACs/mini-splits to work somewhat like MPPT. They would only as hard as they needed to, to maintain a set temperature. This would be based on the volume cooled, insulation value, etc. They only partially work like that. Hypothetical Ex. If someone was trying to cool a small closet, even if was 110F ambient, why would they want the AC to work at 120Hz(poor efficiency), when working at 10HZ(best efficiency) would get the job done, but in a longer time period. If tricking the outside thermistor works, it would be necessary to modify the ambient temperature it sees, so the HZ are high enough to keep up with the inside set temperature. (Not an engineer. Just guessing it would work. Might be easy to test with a mini-split. On a hot day, put outdoor thermistor into cool 75F or so whatever. See what happens with the wattage draw.)
