Per your guidance on that page, I tried one that I hoped was compatible: “Cyber Power Systems ups 2 Value 800E USB (usbhid-ups)”. Every Cyber Power system with USB on the list there seems to use usbhid-ups anyway – so perhaps picking any of them is reasonable?

Picking anything that maps to usbhid-ups does seem reasonable, though it's possible that they pass additional options for certain models (I think FreeNAS does this). I don't know of any that are needed for CPS, though.

>  I can have the TrueNAS system power down when power is lost and the UPS runs on battery, but I see occasional messages about communications being lost with the UPS (saying “Statistics could not be recovered”). I also see statistics being gathered in other alert messages (like it is working fine).

No mention of stability issues for LE825G: https://alioth-lists.debian.net/pipermail/nut-upsdev/2013-November/006563.html (but I don't know different the DG and G models differ)

It is probably worth skimming some of the issues here to see whether there is any wisdom applicable to your case: https://github.com/networkupstools/nut/issues?q=+label%3A%22CyberPower+%28CPS%29%22+label%3A%22Connection+stability+issues%22

Different versions of the underlying OS and NUT might handle things differently, but I don't think I have run across this particular issue (my CPS UPS is currently on a Mac, so I don't see connect/disconnect logs). The usual hardware suggestions are to swap out the USB cable, and try a powered USB hub.
