    My workplace originally had regular UPSes, just like the one you showed, one of the many that would only intervene when the power gets cut.

    It introduces a temporary power loss, in terms of some milliseconds usually, expecting the devices downstream to be able to handle them.

    I had a similar issue on my workplace’s server after a bad storm, then did some research about how to avoid issues when a UPS is present.

    Turns out that there is a whole another category of UPSes, namely Double Conversion UPSes, where the UPS is constantly charging a battery and the battery is constantly powering the load.

    Almost no outside factors can interfere with the load this way, and I’m certain it saved my ass both in the workplace and at home: just a few days ago we had some huge storms, hail, thunder, strong winds and such.

    Power would constantly go out and quicky come back up.

    The initial UPS failed for much less.

    Both my workplace’s server and my home server never felt any of it, cause they’re never directly connected to the power line (unless the UPS is in maintenance mode), and the peace of mind of knowing that they never feel any of that is priceless.

    It’s a good thing that I cannot count how many times they saved me lots of time, mostly because since their introduction I never had a power loss which I previously had with a regular UPS.

    The disadvantage? Much more expensive, since wattage matters more than ever as they have an inverter running 24/7.

    For my workplace I got one that costed about 900 euros, for me I got one that was about 400.
