7.1.5.4 Setting Power Adjustment Parameters

Procedure
Step 1 Choose Settings > Power adjustment to set power adjustment parameters.
Issue 11 (2020-08-30)
Description
Specifies whether to enable the active islanding protection
function.
The standards of certain countries and regions require that when
the output voltage exceeds a certain value, the inverter must
suppress voltage rise by outputting reactive power and reducing
active power.
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.
