When the SmartLogger receives a remote reactive power scheduling command by the PV plant,
Reactive power control mode automatically switches to Remote scheduling. To re-perform the
distributed reactive power compensation, set Reactive power control mode to Distributed power
factor closed-loop control and set Target power factor correctly.

Power Meter: When this parameter is set to Smart meter, the distributed power factor
closed-loop control takes effect.
Electric meter power direction: Set this parameter to positive if the active power
reading of the power meter is positive when the inverter has no power output. Otherwise,
set this parameter to reverse. If you are not sure about Electric meter power direction
after the setting, perform the detection.
Target power factor: Indicates the target value for the adjustment power factor of the
power meter, which should be larger than the appraisal value of the PV plant power
factor.
Adjustment period: Indicates the interval for sending adjustment commands by the
SmartLogger.
Adjustment deadband: Indicates the adjustment power factor precision, which takes
effect when the power factor on the gateway meter is larger than 0.9.
Reactive compensation delay: Indicates the delay time for starting the distributed
power compensation if the current power factor is lower than the target value.
