***An updated after several months of usage, and a change in score to 5 stars as I've learned more about the unit. Buried in the software which is run through your web browser, is a setting to turn down the sensitivity on the incoming voltage which fixes my major con of this unit for me, the unit toggling between ac and battery constantly. *** Very straight forward to setup, the units interface is fairly intuitive to use. Provided me with roughly 30min of power for 2 computers, I7 7700K with a 1080ti, and a I9 10590XE with a 3080, a boat load of SSD drives between them, lots of peripherals and 3 monitors. No blip in the computers performance when switching between battery and ac driven power. Online web interface for real time monitoring of the unit is a nice plus, can send you email reports when issues arise with the unit. Clear instructions to position the unit in it's final resting place before you connect the battery. This style battery shouldn't be moved around once it's connected.

Great value UPS for higher end machines or extra capacity. The LCD status display is a great feature as it gives you detailed status information on the unit no matter what you have it powering. So you can see you estimated runtime with the current load when it powering equipment other than a PC as an example. Plus the new method that APC has for connecting the internal battery is a great design improvement - no short cables to fuss with!
