Misproduction alarms

Last modified: 06 May 2025

Misproduction alarms notify you about the variance between target and measured values for the overall system and individual inverters. There are several methods for estimating the theoretical production (“simulation”) of your system under normal operating mode:

• Machine learning-based simulation

• Physical simulation model, and

• Automatic inverter comparison.

An alarm is triggered if there is a deviation between the target value and the measured value when the minimal threshold value exceeds the minimum deviation of the alarm category "normal". The target value and the comparison to the measured value are calculated on an interval basis, both for the whole system as well as for each inverter every time the data is updated.

Severity: To test the effect of different severity values on misproduction alarms, go to Misproduction alarms > Interactive preview.

Expected power: See Simulation methods for smart alarms

Monitoring threshold: Monitoring begins once the simulated power reaches the defined percentage of nominal power (= manufacturer's indication of the system's power output under normal conditions).

Delay after first occurrence: If you configure a delay, for example, 30 minutes, 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.
