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.
Multiply your server wattage by 8 hours. That’s how much battery you need. It’s probably not going to be a cheap investment.
The alternative would be to keep your ups and invest in a generator you can kick on if there is a power cut, but if it’s every day, that might get rough. Technology connections figured out a build it yourself solution a few years ago https://youtu.be/1q4dUt1yK0g?si=8WOTue9-zGghWlxY

I’d multiply by 10-12 hours to account for losses in the DC-AC conversion.
are there no dc-dc PSUs (or technically just voltage regulators I guess) to relace a PSU with available? That way OP could avoid part of the Ac->Dc->Ac->Dc-conversion related losses he would have with a battery-backup.
The cost of this would be much higher than just buying a bigger UPS I imagine, but it’s definitely doable from the technical standpoint
This was very informative. Thank you!
