I have my settings configured to power down only if ups power is down to 5% or 2 minutes left and STILL it powers down 5 minutes or so into a power outage. I need my storage to be the LAST thing to power down, not the first. Does it just not work properly? I just set all the following to 0 now to see if that prevents it from powering down:

Battery level to initiate shutdown (%): 0

Runtime left to initiate shutdown (minutes): 0

Time on battery before shutdown (seconds): 0

 

I would like it to act as configured though. Anyone use this and have any pointers? (UPS Settings)

The dashboard currently says %46 and 25 minutes remaining at the time of posting this. So it should not have powered off yet.

 

EDIT: It just powered off again with all these setting at 0. This is ridiculous.

Is it initiating an orderly shutdown? Sending alerts and all?

Yes, each time I receive an email that says "unRAID is being shut down".

Do the logs or alerts show the reason? I'm pretty sure I remember the triggering condition listed somewhere.

If the batteries have been deep discharged multiple times, its possible the voltage curve anticipated by the UPS is so wrong that the time remaining drops to 0 without warning. SLA batteries really don't deal well with deep discharge, it really hurts their useable lifespan.

Replace your batteries, I had the same very issue. if your UPS is 3 year or older is time to replace them. Is a DIY job for sure
