If at least one battery is available in your system, you can set up an alarm to notify you if the battery’s state of charge (SOC) falls below or exceeds the tolerated range. This is generally defined in the manufacturer documentation. You can set the alarm severity and delay.
In the example below, a critical alarm will be triggered if the state of charge falls below 30% or exceeds 70%. A delay period of 10 minutes ensures that short downtimes are not reported as an alarm.
Once the alarm is set up, you can view the state of charge as a chart in the Alarms portlet. In the example below, the red line reflects the period in which the state of charge is outside the tolerated range (between 10 AM and 2 PM).
