I recently stated out loud that my homelab was stable, and now my UPS is posting less than 30 minutes of estimated normal load. What’s everyone using as a UPS?
I’ve been rocking the aptly-named CyberPower OR1500LCDRT2U for the past few years. Should I just replace the cells or upgrade the whole unit?
The primary concern is switchover time. A purpose-built UPS can switch in about 10 microseconds. Those large “solar generator” battery packs switch in about 30 microseconds. That might be fast enough, but it’s not guaranteed to be fast enough like a UPS is.
Well, if that is really a concern, you can keep the old UPS with not so good batteries still connected to cover that 20 microseconds difference.
But it is unlikely to matter in a homelab.
