Parameter
Description
Schedule strategy
The value can be Disable, Strategy 1, Strategy 2 or
Strategy 3. The default value is Strategy 1.
● Disable: The SmartLogger controls the solar
inverter to work at full load and will not receive
scheduling commands sent by the management
system.
● Strategy 1: Open-loop scheduling policy. That is,
the SmartLogger evenly allocates the power value
from the scheduling and delivers the average value
to each device, which then operates with the
specific power. The adjustment value delivered by
the SmartLogger is constant. If Adjustment
coefficient is set, the power value will be sent to
the device after being multiplied by the preset
coefficient.
● Strategy 2: The customized function is provided for
a specific power plant. Set Overshoot, Adjustment
period, and Adjustment deadband based on the
scheduling requirements of the power plant.
– Overshoot: Indicates the maximum overshoot
percentage during adjustment. If a PV plant
cannot reach the preset target value due to
factors such as insufficient sunlight, the set
target value is the current value plus the
overshoot.
– Adjustment period: Indicates the time required
from adjustment instruction delivery, device
response to the instruction, to the detection of
the preceding actions by the SmartLogger.
– Adjustment deadband: Indicates the
percentage of the adjustment deviation value to
the rated output capacity. In the adjustment
deadband, strategy 2 does not deliver control
instructions but still detects the deviation in real
time.
● Strategy 3: In the feed-in limitation scenario of the
master and slave SmartLoggers, set this parameter
to Strategy 3 for the slave SmartLogger.
Adjustment coefficient
Coefficient for calculating the target value of active
power adjustment. The default value is 1.000.
Shutdown upon
communication
exceptions
The default value is Disable. If this parameter is set to
Enable, the SmartLogger shuts down the device when
the communication between the SmartLogger and the
scheduling backend is interrupted for a period longer
than the set value of Time for communication
exception detection.
