Misproduction alarms

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 and for each inverter each time the data is updated.

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

Nominal power: The manufacturer's indication of the power output of the system under normal conditions. For example, if a PV system has 100 kWp of power and you set the nominal power to 7.5%, the misproduction alarm is only triggered if the system exceeds 7,5 kW of power. 

Delay: If you configure a delay, e.g. 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.
