Seems a bit odd that it doesn't give you an estimated runtime at 50% and 100% load. Most UPS manufacturers do. You'll probably want something that's double the size of your max load though if you want more than a couple minutes.

Great advice guys! Im wondering if there is a proper way to calculate the approximate runtime just based of the battery capacity and system load? Maybe I should look for as @JD said something that will double my max load (and with estimated runtime info that is transparent)

1200va UPS
300w PC load

1200/300 = 4

60min/4 =15 min

This is very rough math.

Edit: actually...without doing a whole bunch of digging and research on your gear, the gear you're buying, etc...the 'easy answer' is to get a UPS that can handle 2x max watt draw you'll see, and then spend as much as you can to get the longest runtime (aka biggest VA) within your budget.

I knew there must have been a calculation! thanks!

The ubiquity gear (USW-Pro-24-POE and UDM-Pro) I picked the USP-RPS
Which will all reside on its own proprietary rack U-Rack-6U-TL

And I have a Dell PowerEdge R250 with a Dell PowerVault NX3240 (combined 1200watt max)
which will be wall mounted above the ubiquity in a Tripp Lite SmartRack 6U.

For the Server and Nas I dug around and found this unit, I really like the litium Ion batery and they calculate at 100% load (1200watts) It will run for ~ 13min 55s.

USP-RPS

This is a very poorly named product FYI - it offers no battery power, it's simply gives you a redundant PSU for UniFi equipment.

They have the USP-RPS-Pro in Early Access which does have a battery input, but still does not include a battery. The USP-Battery remains unreleased.

You'll need to plug everything into a UPS.

Ahhh crap! I thought the Unifi power connectors were proprietary.

Holy crap. I'm sure glad I didnt buy one, and I was watching for stock, because even I assumed it was a ups. Agreed, poorly name product for sure.

Yeah I was hoping it was a 12V DC UPS too, as that would obviously be way more efficient, but alas it wasn't.
