Total outage alarms
Last modified:
Total outage alarms reflect a total outage of an inverter, a string combiner box, or the entire system. An alarm is triggered when the actual (measured) power drops below 1% of the nominal power.
Parameters
Expected power: See Calculation methods for total outage and misproduction alarms.
Monitoring threshold: Monitoring begins once the expected power reaches the defined percentage of nominal power (= manufacturer's indication of the system's power output under normal conditions).
Example
For example, with a 100 kW system and a threshold set to 7.5%, the alarm is only triggered if the expected power exceeds 7.5 kW and the other trigger criteria are met.
Delay after first occurrence: If you configure a delay, an alarm will only be triggered in case of persistent incidents. This helps to avoid alarms for deviations that only occur for a short time.
Example
Based on the settings in the screenshot below:
The machine learning simulation will calculate the expected power.
When the monitoring threshold of 5% is exceeded, a critical alarm will be triggered if the outage persists beyond 30 minutes.
