Pros
- Fits a standard 19 in rack in 1U, for telecom and server closets
- Built-in transfer switch keeps loads on utility power and switches over in under 20 ms
- Front status display and RS232 port for remote monitoring
- Idles at about 14 W, low for a rack inverter this size
Cons
- No charger, so the 48 V bank needs its own rectifier or charge controller
- No UL listing, which some data-center and telecom sites require
