Great Battery Backup!
By Brian P. on Reviewed in the United States on July 26, 2011
These TrippLite units are a GREAT battery backup! I can't say enough good things about them - and I would rate them far higher than an APC battery backup.I work for a Cooperative telephone company that is also a wireless Internet service provider - and we have close to 20 of this units out in the field - some for over 5 years without issues! We also install them for many other customers as well, just because they perform so well.If you have an application where you will be using a battery backup to provide backup power until a standby generator can take over the load - these units will not shut down because of the dirty voltage coming off of those generators.We have had one 1000VA unit at a customer site that had a failed cooling fan (the UPS did NOT shut down, God knows how long that fan was off for) - and TrippLite customer service shipped us our a replacement promptly, and we were able to replace the unit at a time that did not affect that customer's business.I have also personally replaced the batteries in both the UPS itself, and the additional battery packs for these units. I was able to perform this maintenance on a production site during the middle of the day - and everything went smoothly. While it's not the easiest to get your hands in the tight places to connect the batteries - I would have to guess that's about the same with all UPS units with replaceable batteries.Again - great units - you will not be disappointed!

Sooooooo Loud
By Steve K. on Reviewed in the United States on December 16, 2022
I bought this Tripp Lite 2200VA RM unit to replace 2 1500VA RM units from CyberPower. The CP units were virtually silent, unless a power outage occurred, then alarm beeps and fan noise were enough to raise Elvis.The bad:After installing the this Tripp Lite 2200VA unit, immediately after plugging it in, it started squealing and buzzing. This was not the fan or an alarm, this was the charging circuitry. It sounded like the caps were boiling away and about to have a critical failure.This is in my home office, and you could here it buzzing in the living room, which is 25' down the hallway.Unplugging and letting it go into inverter mode made the sound go away. Same if you did a battery test. Plugging it back in, or after a batt test, the very loud squealing and buzzing returned.Called Tripp Lite tech support and they tried to convince me this was "normal". He said I had purchased a data center class product and noise was expected.1) Data center UPS' would be something much larger, like 5000VA or a dedicated UPS cabinet, not a rinky dink 2200VA UPS.2) It's marketed for small office and home office use, where noise would be an issue.3) The Tripp Lite tech didn't sound like he cared if my house burned down.After working in IT procurement for 25 years, I have never, ever heard a UPS that was this loud. And there was definitely nothing normal about it. The rude and disinterested tech left a bad taste in my mouth, too.The good:Great rail kit included, easy and quick to install.Liked the LCD panel and how easy it was to change settings and test the battery, with multiple levels of dimming. You could also set it to continuously scroll through the various statuses.
