Question CyberPower CP1350AVRLCD3

[kanewolf]

here is something puzzling to me. On CyberPower's site, they list the CP1350AVRLCD3 as running for 14/4min on half/full load. but they have the CP1500AVRLCD3 running for 12/3min on half/full load. why would that be? could it be a misprint?

The two units use the same battery. So, a unit with a higher allowable VA rating will have a shorter runtime. The 9AH battery is the limiting factor.
My APC commercial 1500VA UPS uses four 12V 9AH batteries. Still 1500VA but four times the battery reserve. You can't use the VA rating to judge a UPS.

ah I see. so why would someone spend more on the 1500 model if the battery won't last as long as the 1350 model?

If they have a load (VA) greater than the 1350 will support, it may just error and not support at all. But the 1500, might carry it for a short time.
This all goes back to my statement in post # 17. You HAVE to measure you actual usage. You are just guessing about everything without actual power measurements.

ok I understand.

I know, i'm just trying to understand how it works right now. i'm reading from others that have more things plugged into theirs and the battery is lasting very long. i might just buy the 1350 model and see how long the battery lasts. if its not long enough, I can return it to amazon. I don't want to spend another $60 on the electricity usage monitor.

I bought this one when I needed a second one. Figured I try a cheap one and see. no issues and seems to work as good as the killawatt

Here is a QNAP how to -- https://docs.qnap.com/operating-system/qts/5.0.x/en-us/configuring-the-ups-settings-2AD2FE5E.html
You put a USB cable between the port at the top of the UPS and your NAS. Then you configure the UPS monitor software on the NAS. When the UPS battery gets low it will automatically shut down the NAS. I wouldn't worry about network gear.

how do you put the UPS software on the nas? I can't find the software in the available applications to download on the nas and the Cyber Power site only shows this application available for windows, mac or linux.

cool so I don't even need the UPS software installed on my machine.

Thats a direct screencap from my Control panel.

The UPS knows it is on battery. The QNAP senses this via USB, and acts accordingly.

Thanks everyone for all your help!!!

Update: it takes almost 24 minutes to shutdown my nas. About 20 minutes just to stop Virtualization Station with a VM still running. I suspect it would be quicker if i first shutdown the VM then shutdown the nas, but i wanted to see how long it would take in a case where the power goes out during the night or when i’m not home.

It's not a misprint. This is what confuses many people. Both models use the SAME two batteries inside. The 1500VA version can just handle more load, which means the batteries wouldn't last as long at half of that load. If you put the same load on the 1500VA unit as you put on the 1350 (not a half load, but the same load on both units) then they would both probably last the same amount of time.

Your actual runtime is probably only going to be measured when you have the unit in hand, plugged in, and testing it.

I know this now. I plan on getting the CP1350AVRLCD3 today.
