How Do I Set Anti-crosstalk Parameters?
When MBUS 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 SmartMBUSs 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 SmartMBUS in a subarray, you need to reset the anti-crosstalk parameters of the device.
Setting Anti-crosstalk Parameters Through an SN List
- Collect the SNs of the inverters in the subarray corresponding to the SmartLogger.
- Log in to the SmartLogger as Advanced User and choose .
- On the SN list tab page, click Template and fill in the collected SNs based on the template.
- Click Import to import the SN list to the SmartLogger.
- On the Running Param. tab page, set SmartMBUS parameters Box-type transformer No. and Winding No. as required, set Anti-crosstalk to Enable, confirm the selected items, and click Submit.
- Click Synchronize to synchronize the transformer station number and winding number to the inverter in the subarray.
Setting anti-crosstalk parameters based on the transformer station number and winding number.
- Log in to the SmartLogger as Advanced User and choose .
- On the Running Param. tab page, set SmartMBUS parameters Box-type transformer No. and Winding No. as required, set Anti-crosstalk to Enable, confirm the selected items, and click Submit.
- Log in to the SUN2000 app as Advanced User, choose , and set transformer station number and winding number for all inverters in the subarray as required.
