I’m running a rather small homelab and am hunting for a good UPS to help keep everything running smoothly. My top priorities are:

  • Just enough battery life to keep things running until they can be shut down
  • Compatible with open source software for monitoring and automated shutdown

Would I have better luck getting a used one and a new battery, or a brand new unit altogether? Anyone have one they don’t need anymore, on that note? 👀

Thanks for the advice!

    Parallel won’t show current load of a device. Even a clamp type can be thought of as serial, it’s just picking up the EM field instead of actually carrying the current load across the device.

    Something in parallel will be powered by the same source, with it’s current load independent of the other device.

    (And yes, I had to think about it for a second, it’s not always immediately intuitive for me either.)

      Pfff current I was brain-dead, yes.

      There’s smart plugs that measure current, I have some Emporia plugs at home.
