Communication
abnormality output
(%)
Communication is abnormal, and specified dispatch output
value is delivered.
Control method
Open loop control: Reactive instruction controlled by AI is sent
to power output port of the inverter, thereby achieving active
power control.
Closed-loop control: Reactive instruction controlled by AI 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.

Q-Method
PF: set the power factor as the target value
%: set reactive power percentage
Min. / Max.
When "Q-Method" is set to "%", the parameter ranges from
-100.0% to 100.0%.
When "Q-Method" is set to "PF", the parameter ranges from
-1 to -0.8 or 0.8 to 1.
Step
The minimum difference value between two consecutive
power dispatching instructions
Hysteresis range**
When the parameter "Q-Method" is set to PF, dispatching
output maintains to be PF±1
Note: *Only when the control method is set to "Closed-loop control", the parameter "-
Select energy meter" is settable.
** Only when the control method is set to "Open loop control" and the Q-Method to "PF"
or when the control method is set to "Closed-loop control", a Smart Energy Meter is
selected, and the Q-Method is set to "PF", the parameter "Hysteresis range" is settable.
Step 4
After finishing parameter setting, click "Save" to save the operation.
