I'm not really sure exactly how to the drop out works.
I thought I explained it here:

It's all good. Just to clarify, your unit is both a converter (battery charger) and inverter (12v to 120v AC). When the AC input power is good from a shore cord or generator, it charges the batteries along with sending the power to all of your AC circuits. When the AC demand exceeds the supply, it scales back the battery charging. When the AC power input voltage drops too low (dropout level) it assumes the power is insufficient and switches to inverter mode. The idea is to keep AC power inside the camper when outside power goes away without a manual switch. Since the generator was loading down when the A/C started up, the voltage dropped enough to trigger the switch to inverter mode, followed by cutting out since it couldn't power the A/C. Lowering that dropout level allows that temporarily low voltage through long enough for the A/C to spin up and the generator to recover.
