How do you keep your home servers online during powercuts? (lemmy.ml)

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.

I agree. Its never worth the risk.

I think I'll start with inverter + battery. Then add batteries in the future depending on my power needs.

There are inverters that support battery backup, recharging from solar and grid power that are supposed to go between your grid tie-in and the rest of your house. Quite a ways more expensive, but the battery capacity is probably relatively cheap compared to UPS power and is essentially a backup for your entire house.

The one I read about a while ago was a Growatt that is basically an all in one box. Can provide power from batteries, recharge from solar or grid power, feed back excess solar power to the grid, etc, you name it. And I can imagine other brands producing the same solution.

I'm lucky enough to live in a country with almost no power cuts though. I think we have at most 1 a year for max 10 minutes. So can't say I have any experience with it myself.

If going for an inverter try a sin wave one if it's in your budget.
