10.6 Power 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.
