Control method
Open loop control: Reactive instruction controlled by DI is
sent to power output port of the inverter, thereby
achieving active power control.
Closed-loop control: Reactive instruction controlled by DI
is used as target value and reactive power and power
factor of the meter need to be collected and used as
input parameters, and reactive power compensation ratio
is calculated and sent to power output port of the inverter.
Generally, this strategy is used for improving the power
factor of the property boundary point.

Communication
abnormality output (%)*
Communication is abnormal, and specified dispatch
output value is delivered.
Control cycle*
Time interval of delivering dispatching instructions
Parameter range: 5~60s
Q-Method
PF: set the power factor as the target value
%: set reactive power percentage
Note: The parameters noted with * refer to the parameters that need to be set only when
the Control Method is set to “Closed-loop Control” .
