Liebert Nfinity 20KVA UPS/battery backup

Description: Liebert Nfinity 20KVA UPS/battery backup - TESTED/WORKING $4,500 or BO PICK UP ONLY This UPS can be used to backup an entire small data center or computer room. Or an entire average household. It works great. I used it in a project to keep my house running 24/7, using a home standby generator and this UPS. I am working on other projects and no longer need this UPS. As you can see in the pics, I did a test on 5/29/2019 and it works great. The batteries are getting a bit older now but they still worked. You can see the project I did that includes this UPS and a youtube video of it in action at: https://imgur.com/gallery/OyGCO The UPS is configured to Liebert Nfinity model NB20S0712600. AC Input 208v or 240v single phase. UPS Output 208v or 240v single phase. It must be hard-wired. I am using the 240v setting, it is feeding my entire house panel EXCEPT the central air (A/C) and electric range/stove as these draw a little too much power for the UPS. Also the A/C has a high 'start' current draw. You should not run high start current items (i.e. larger motors, etc.) on any UPS. The unit has qty 6 - 4KVA power modules. Is N+1 for redundancy. I.e. if one fails, the UPS can still provide the full 20KVA power. If two failed, it would then provide 16KVA power, and so forth. Has qty 6 - battery modules. If one or more fails, it will still carry the UPS, just not as long as if all 6 modules were working. Each battery module contains qty 10 - 12v 9ah batteries. This UPS works by always supplying power through the inverter. When the utility/input fails, there is *no* switchover time, because it is always on the inverter output. Also the output is always a clean, pure sine-wave. It has a network management module. It has management/configuration/alerts functionality using Liebert Multi-Link windows software over tcp/ip ethernet. It also has serial ports for direct software communication. The UPS has a fan on each power module and two fans at the base of it that are always running when the UPS is in operation. The total noise is not very loud. In comparison, a rack of servers is definitely much louder. The unit is 54" tall, 20" wide and 28" deep. It is quite heavy, around 1,176lbs fully loaded like this according to the docs. The power and battery modules can be removed to lighten the main unit. It is generally easy to move around on flat/hard surfaces as it has small caster wheels. This sale also includes a power distribution box with different outlets (see pic) that came with the UPS when I originally got it, but I never used it. Manuals and a CD of software included.
