I live in a part of the world where powercuts are pretty frequent. 1 per day is normal. They last between 1 and 8 hours. A day without powercuts feels like a special occasion.

My machine is powered by a desktop ups which is terrible. It is only supposed to power everything for a few minutes to shutdown safely. But it is cheap and I don’t know much about other affordable alternatives.

How do you folks who self host at home deal with powercuts? Any recommendations? 8 hours of uptime from a ups sounds almost impossible or totally unaffordable to me.

      It’s very homemade, but I believe it’s built like a DC net for a boat. It’s a bluetooth connected lithium battery, boat cabling and fuse boxes and Victron charger and voltage transformers.

      I built it with “subnets” for different voltages. The battery is 24 V which feeds servers and a 34” monitor, then a transformer to 12 V for network gear, and several 5 V (USB) for a rack of raspberry pis. The is also a small 230 V transformer, for some gear that have built in PSU.

      The largest server is fitted with a custom DC PSU I found on e-bay, others are normal external PSU where I cut the cables.

      Forgot to add that a big part of the setup is in the battery controller, which I built on my own. :) That was a very fun project, and now the battery is fully automatic and charging is based on hourly price and the power provided by my solar panels.
