The UPS supports a rack-mounted server array as well as the power supply circuit for PCs, modem-routers, and laptops in a medium-sized business system.
It operates quietly, its collaboration via Ethernet with the system administrator is satisfactory, its indicators have sufficient accuracy, and its response to fluctuations and interruptions in power supply is as expected.
The battery array seems to perform well so far, and the overall impression of the UPS gives a sense of adequate coverage for the needs of a medium-sized business (which, notably, is installed in a heavily loaded area in terms of DEH loads).
UPDATE:
After about a year of operation and several activations during voltage dips and DEH power outages, it continues to behave exemplary without any indication of a decrease in battery capacity.
It remains quiet, and its software appears to be sufficiently accurate in its reports, particularly regarding the duration of power supply during DEH voltage interruptions.
