was your Inverter actually ON when this happened? The Inverter typically passes thru 120v power from the Shore when you are plugged in, but if the Inverter is ON, it would then pick up the power, even for just an instance, when the shore power is lost... meaning, you would not experience any power loss to the appliances and outlets.
I doubt your EMS has anything to do with this, it could simply be a temporary black-out or brown-out, park wide, or even utility wide.
This is why we always keep our Inverter ON, whether plugged in, the generator running, or not. The Inverter's power is the 'back up' power supply - instantly.
