UPS Backup Recommendations

[kromberg]

hello, i am looking for a UPS backup unit that is compatible with proxmox where it can read the remaining battery life and shut down things based on life left thresholds. Not looking for a mid level range unit.

many models are supported by "apcupsd" (need install with apt) , here I use HPE T1500 (EATON rebranded) edit: with usb
it's not integrated in PVE interface and need basic configuration to enable it.
edit: Mails even works directly when postfix configured. Mail on power failure and Power return.
Like any Linux distrib.

And there is also NUT which can do this: https://networkupstools.org/stable-hcl.html

I do know that the UPS is supported/driven by apcupsd and NUT, but various manufactures have differing levels of support and functionality by the driver and higher level software. I am mainly looking for peoples experience with different manufactures/models that have good usable support.

with HP T1500 Gen5 / EATON equivalent , after a test on battery during 1h , on idle server.
Gracefull shutdown is done correclty too by apcupsd.
