Reactive Power Fix Control and Power Factor Fix Control
The SmartLogger provides simplified local settings for the reactive power fix control and
power factor fix control, which applies to small-scale grid-tied PV power generating systems
or power stations with attendants. The SmartLogger also supports the automatic local power
control, that is, to automatically adjust the reactive power reduction absolute values and
power factors in different periods of the day.
Users can specify the settings based on the output features of the power station. The
SmartLogger will control the reactive power output of the inverters according to the user
requirements.
Set Reactive Power Control Mode to Reactive power fix control or Power factor fix
control, as shown in
Issue 04 (2013-12-15)
 A maximum of 16 levels is supported for power factors.
"√" means low level. When the four DI ports in the SmartLogger are connected to the GND2, low

level is indicated; when they are not connected to the GND2, high level is indicated.
 The power factors of DI1, DI2, DI3, and DI4 should differ from each other. Otherwise, an abnormal
command is generated.
 If the SmartLogger supports both active power control and reactive power control, DI1, DI2, DI3, or
DI4 can be selected only once. In this case, four power factor levels are available.
If a "√" is under Capacitive, the power factor is a negative value, indicating that the power grid

supplies reactive power to the PV power station. If no "√" is under Capacitive, the power factor is a
positive value, indicating that the PV power station supplies reactive power to the power grid.
