10.6Power History
The power history is only available when the inverter is blocked; it provides a visual display of the status of the alarms and measurements over a period of 10 seconds before and 1 second after the inverter stops in steps of 0.1 s. The power history is lost when the inverter is restarted.
Figure 20 provides a graphic representation of how to access the Power History.
