Communication
abnormality output (%)
Communication is abnormal, and specified dispatch
output value is delivered.
Control method
Open loop control: Remote monitoring background is
connected and active instruction of remote dispatching
is sent to the power output port of the inverter, thereby
achieving active power control.
Closed-loop control:
• In case no Smart Energy Meter is selected, remote
monitoring background is connected, active
instruction of remote dispatching is used as target
value, and active power compensation ratio is
calculated and sent to the power output port of the
inverter. Generally, this strategy is used for fast and
accurate active power regulation.
• In case a Smart Energy Meter is selected, remote
monitoring background is connected, active
instruction of remote dispatching is used as target
value, active power of the meter needs to be
collected and used as input parameter, and active
power compensation ratio is calculated and sent to
the power output port of the inverter. Generally, this
strategy is used for anti-backflow or avoiding zero
power feed-in.
Select energy meter /
transformer*
Unselected
Select Smart Energy Meter / transformer involved in
power regulation
Error limit (%)*
Adjustment accuracy If the ratio of the difference
between the active 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,
increase or decrease adjustment value according to the
set adjustment ratio, so as to reach the target value.
Control cycle
Time interval of delivering dispatching instructions
Parameter range: 5~60s
Note: *Only when the control method is set to "Closed-loop control", the parameter "-
Select energy meter / transformer" is settable.
