10.1 How Do I Set Anti-crosstalk Parameters?
When PLC is used for communication between the SmartLogger and the inverter,
anti-crosstalk parameters must be set in the following scenarios:
The SmartLogger detects inverters of another subarray.
The SmartLogger detects more inverters than those belonging to the corresponding
subarray, while an adjacent SmartLogger detects less inverters than those belonging to
the corresponding subarray.
The AC power cables for different transformer stations are routed along the same trench
or cable trough.
The voltage on the high-voltage side of the transformer station is 10 kV.
There are multiple windings on the low-voltage side of the multi-split transformer station,
such as the dual-split transformer station.
Two or more PLC CCOs are installed on the low-voltage side of the transformer station.
After replacing or adding a device such as an inverter, a SmartLogger, or a PLC CCO in a subarray, you
need to reset the anti-crosstalk parameters of the device.
Setting Anti-crosstalk Parameters Through an SN List
Step 1
Collect the SNs of the inverters in the subarray corresponding to the SmartLogger.
Step 2
Log in to the SmartLogger as
Advanced User
and choose

.
Step 3
On the
SN list
tab page, click
Template
and fill in the collected SNs based on the template.
Step 4
Click
Import
to import the SN list to the SmartLogger.
Step 5
On the

.
Step 6
Click
Synchronize
to synchronize the transformer station number and winding number to the
inverter in the subarray.
