Have you configured nut to talk to your UPS?  You'll need to follow the 
configuration information in the nut user pages here: 

I would also do a google search for 'nut tripplite avr-550u' and see 
what kind of information you find, I would also search ubuntuforums.org 
for your UPS model.

At a minimum, you need to configure hosts.conf, ups.conf and upsmon.conf 
- you should also understand what all the options do, as this will have 
a critical effect on how the UPS behaves when it loses mains power.
