Parameter
Description
Target power factor
Specifies the target value for the adjustment power factor of
the power meter. The target value should be larger than the
appraisal value of the PV plant power factor.
Adjustment period
Specifies the interval for sending adjustment commands by
the SmartLogger.
Adjustment deadband
Specifies the adjustment power factor precision.
NOTICE
This parameter is valid only when the power factor of the power
meter is greater than 0.9.
Reactive compensation
delay
Specifies the delay time for starting the distributed power
factor compensation if the current power factor is lower than
the target power factor.
When the SmartLogger receives a remote reactive power scheduling command from the PV
plant, it automatically changes Reactive power control mode to Remote communication
scheduling. If power factor closed-loop control is required, set Reactive power control
mode to Power factor closed-loop control and set the target power factor correctly.
6.4.4 Setting Export Limitation Parameters
Context
When the PV plant generates power for self-consumption, countercurrent may feed into the
power grid if the loads cannot consume all the power. In this case, you can set the export
limitation parameters over the WebUI to prevent countercurrent.
Scenario without a circuit breaker: The countercurrent feeding into the power grid can be
eliminated by sending a command from the SmartLogger to lower the solar inverter
output power.
