Just to clarify, generators can be prone to issues with under voltage and over voltage (your stabilizing stattement) and can fail by loosing a line, the netral or ground. The EMS from the sounds of it is doing exactly what it should do. That time for the generator to stabilize is worth the wait vs risking damaging your equipment IMO.
