I run my own DNS servers and Mail server, I have purchased a few battery backups that are available, they work but they only work for a limited time. With one backup per computer, which I have 3, they will run for about 45 minutes if the power goes out. None of them work properly with Windows Server 19 to shut down system then restart when the power comes back on. I have had to make multiple emergency trips to my home in Arizona where they are setup, just to turn them back on. Yes it sucks.
I decided to make my own battery backup system modeled after my Solar powered well that has been working for over 10 years flawlessly. Here is what I did to overcome the crappy battery backup systems made.
I took one of the over the counter battery backup systems and plugged the 2 routers into it, it will run both for at least 24 hours which is generally more than enough time for the power to come back on.
Now for my 3 servers I bought a (110 Volt/ 24 volt DC) Magnum MS 2024 Grid Tie Inverter, 4, 6 volt 225 AmpHour Golf Cart batteries from Costco, some wiring,cables,... and set it all up. Total cost about $2500 Since it is a Grid Tie Inverter, I have it plugged into the wall socket to keep batteries fully charged.
With this setup, when the Power goes out, it will run for at least 24 hours without a hiccup, the switching is fast enough to not affect the computers and doesn't even flinch when the power goes down, NO more emergency trips, I still come here every 2 weeks for updates and maintenance and usually the power has gone out while I was gone, but EVERYTHING stays up and running.
Just hope this helps anyone else that runs their own servers

Can Linux be configured to shutdown properly with the backups you have? If yes, virtualize the Server 2019 machines under Proxmox.
Restart after power loss is, at least in the Dell servers I'm most familiar with, a setting in BIOS.
No boat so I don’t need an anchor. 😂👍
Generacs were known for becoming boat anchors.
I haven’t read the latest warranty.
In the past if you ran one for an extended period, you voided the warranty.
