This is the only way to reset the UPS: shutdown the load, shutdown the
UPS, unplug the UPS, wait a few seconds, plug it back and turn it on.

Did you try to play with the "notification" parameter ?
here is the ups.conf file I use on an MGE Ellipse 800 S:
driver = mge-shut
port = /dev/ttyS0
ondelay = 6
offdelay = 50
lowbatt = 15
notification = 3
