7.1.5.4 Setting Power Adjustment Parameters

Procedure
Step 1 Choose Settings > Power adjustment to set power adjustment parameters.
Issue 10 (2020-03-28)
Description
The standards of certain countries and regions require that the inverter
generate a certain amount of reactive power when the output voltage
exceeds a certain value.
This parameter is displayed when Voltage rise suppression is set to
Enable.
The standards of certain countries and regions require that the active power
of the inverter be derated according to a certain slope when the output
voltage exceeds a certain value.
 This parameter is displayed when Voltage rise suppression is set to
Enable.
 The value of Voltage rise suppressing active power derating point
must be greater than that of Voltage rise suppressing reactive power
adjustment point.
The standards of certain countries and regions require that the inverter must
shut down after the communication is interrupted for a certain time.
If this parameter is set to Enable, the inverter automatically starts after
communication recovers. If this parameter is set to Disable, the inverter
needs to be started manually after communication recovers.
Specifies the duration for determining communication interruption. Used
for automatic shutdown for protection in case of communication
interruption.
Specifies the duration for the power to gradually increase when the inverter
starts.
Specifies the time for the power to gradually increase when the inverter
restarts after the power grid recovers.
