Control method
Open-loop control: Remote monitoring background is con-
nected and active instruction of remote dispatching is sent to
the power output port of the inverter, thereby achieving active
power control.
Closed-loop control: Remote monitoring background is
connected and reactive instruction of remote dispatching is
used as target value, 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.
Query recovery time
Data interaction with the inverter will be suspended after the
power control instruction is sent. During this time period, the
device executes the power control function only; after the
end of this time period, data interaction with the inverter will
be resumed.
Range: 0 to 60s
Frame Delay
Time interval for data interaction with the inverter while exe-
cuting the power control function.
Range: 4 to 70ms

Error limit (%)*
Adjustment accuracy
If the ratio of the difference between the reactive power and
the target value to the rated power is within the set error
range, the target value is reached.
Adjustment ratio (%)*
If the adjustment does not reach the set target value, in-
crease or decrease adjustment value according to the set ad-
justment ratio, so as to reach the target value.
