Notification: UPS ups battery is low

fjmp24

Hi,

I receive the notification "UPS ups battery is low" and I don't understand why.
I changed the battery without success.
I changed UPS (EATON ELLIPSE PRO 850) to a more powerful one without success.

Do you have an idea ? Sorry I'm newbie Thanks.

My UPS status:

My UPS Extra Arguments to driver

ignorelb
override.battery.runtime.warn = 1800
override.battery.runtime.low = 1200
override.ups.delay.shutdown = 600

With the EATON ELLIPSE PRO 850, I have less notification.
The UPS powers a Synoloy NAS and a PC (I7)

You indicated that you have 3 systems powered by the UPS, however your post does not include the notification that you are referring to, nor any information about the circumstance when the notification occurs or which system it originates from.

Btw, unless you are trying to address a very specific problem, you should not have the items in the "Extra Arguments to driver" section. Specifically, setting "ignorelb" and specifying runtimes is almost always a mistake, although a commonly made one. Likely the only one that should be there is the shutdown delay, but that only if you need more than 20 seconds to completely a shutdown on one of the systems. My expectation is that would probably only apply if you are running the Synology as a remote client to pfSense.

@dennypage Thanks I deleted override.battery.runtime.low and override.battery.runtime.warn and I don't receive notifications anymore. But I have another questions.

When I cut power to my NUT, pfsense sends a shutdown when my NUT have :

runtime is equal to 0:01:41
battery charge is equal to 19%
Why doesn't it send the message when runtime is equal to 0:05:00 ? I set override.ups.delay.shutdown = 300

Once my devices have been shutdown, the NUT runs for about 1 minute and displays the runtime. Then it doesn't display runtime and works about 0:02:49. I don't understand how it works.An idea ?

Below my configuration:

battery.charge	9
battery.charge.low	20
battery.runtime	355

Thank you for your help and sorry for my newbie's questions.

NUT initiates a shutdown when the UPS declares that the battery is low (LB). The decision regarding a low battery is made by the UPS itself. Some UPSs have configurable LB levels, and some have fixed LB levels. If your UPS has a configurable LB level, this is configured by the battery.charge.low variable. 20% is a common default.

When performing a shutdown, one of the last steps is for the OS (pfSense) to instruction the UPS to cut the power. After receiving that command, the UPS waits a short period of time before it actually turns off the power. The purpose of this delay is to allow the OS to complete its shutdown before power is cut. Some UPSs have configurable delays, and some have fixed delays. If your UPS has a configurable delay, this is configured by the ups.delay.shutdown variable. 20 seconds is a common default.
