No Output
Parameter
Description
Reactive power control
mode
If the PV plant is not required to adjust the voltage at the
grid-tied point or perform reactive power compensation, solar
inverters can run with pure active power output. In this case,
set this parameter to No output.
DI Reactive Scheduling

When setting this function, ensure that the user-defined DI port is not occupied. Otherwise,
the setting will fail.

SmartLogger scenario: Before setting this function, ensure that the SmartLogger is
properly connected to the Ripple Control Receiver.

SmartLogger+SmartModule scenario: Before setting this function, ensure that the
SmartModule is properly connected to the Ripple Control Receiver.

Parameter
Description
Reactive power control
mode
Set this parameter to DI reactive scheduling.
DI
NOTE
DI parameters include DI1,
DI2, DI3, DI4, and Power
factor.

Sixteen levels are supported for power factors.

"√" indicates a low level. When the four DI ports of the
SmartLogger are connected, the ports are low-level ports.
When not connected, the ports are high-level ports.

The percentage levels of DI1–DI4 should differ from each
other. Otherwise, an abnormal command is generated.

If the actual input DI signal is inconsistent with that
configured on the WebUI, the SmartLogger controls the
solar inverter to work at full power and the Abnormal
Reactive Schedule alarm is raised.
