Thanks for posting the link to the video.
I see that voltage dropped to 59 when the compressor started up. The lowest I've seen before the Microair installation was about 96. That was enough to concern me.
Voltage drop now is limited to about 10. I.E. if shore is at 113 then sag is to 103. Then the autoformer 'kicks in' and voltage goes up to 118. It may be that the Kill-a-Watt meter is not "fast enough" to display the start up voltage sag correctly, but I'm certain it is much less with the microair in place.
Did you ever try to start the air with the generator in eco mode?

Perhaps this will help - here's a video I made a few years ago powering my Coleman Mach 3+ 13,500 BTU A/C with my EU2000i. A/C was equipped with an SPP6 hard start cap, I wired the thermostat with a Fan HI / Fan LO switch with a centre off position so I could start the A/C compressor only, then manually start the fan a few seconds later once the compressor came up to speed. As you can see voltage drop under full load of the A/C compressor and fan was about 4 volts.
