A compressor is a compressor and the laws of physics as applied to electric motors don't change. All electric motors have a starting surge, and a motor that starts under load (any compressor) has an even greater surge.
Yes, the physics do change depending on the compressor. Most are slow start now or with large starting capacitors. Many homes still have the old glass fuses so they must accommodate them.
Many of you ignore the fact that a rooftop unit doesn't even come close to the amount of air volume that comes from a house unit. All those rooftop manufactures are selling a half truth. They advertise xxx CFM but when you actually dig deep that figure is xxx CFM BEFORE the evaporator. What actually blows out if not even close. A home AC measures CFM out the front what you actually feel. NOT before the evaporator.
The LG 15,000 BTU AC I ordered specs say 1,260 watts to run and 11.8 amps. More then enough that a 3,100 Champion can supply.
Either way, I plan to do a test next week and will video tape. I have a series of tests I plan to do.
Full run mode then turn on
Eco mode then turn on
Full mode then turn on then turn on eco mode and see how compressor kicks on and off and how much generator ramps up
I will also be running all these tests with a watt/amp meter attached and record results.
The watt/amp meter also records peak but from what I'm told that surge may only last milliseconds and not be able to be caught by the meter and only with a scope.
Anyways, the proof will be in the video I make so we can put this to rest.
