I'm looking for a new UPS to replace an almost 10 years old APC beast that's having issues, but I'm not sure what to buy.
I'll be using it to power a small home server and some network equipment in an area where there are occasional power outages (but they last 2-3 hours). My requirements are:
300-600€ range
At least 1500VA, 900W
Doesn't make noise unless it's on battery
Must not require proprietary software to monitor it or to calibrate the battery and other basic stuff (if it works with apcupsd or NUT it would be perfect)
