generator power does not kick off and back on
an inverter might do this, but a whole house inverter should default to gnerator power, just like it does to shore power
an EMS could do this if it is wired after the transfer switch, and generator voltage drops too low when trying to start the A/C
which would indicate a problem with the generator or the A/C unit, like a bad start capacitor for the a/c compressor, or compressor going bad
the MW is nothing but an indicator of power loss and power return
should also indicate power return IF you turn off the A/C when the drop out occurs
