Operation Procedure
Step 1 Set the box-type transformer number and winding number of the PLC CCO module.
1. Plan the box-type transformer numbers of the entire PV plant and map each box-type transformer number to a unique PLC CCO module. The box-type transformer number ranges from 1 to 511, and 0 indicates an invalid box-type transformer number. For the scenario with a multi-split transformer, further distinguish to which winding the SUN2000 belongs.
2. Connect the mobile phone app to the SmartLogger2000 over Bluetooth, and set the box-type transformer number and winding number of the PLC CCO module.
Fora multi-split box-type transformer, set the number of winding 1 on the low voltage side to 1, and the number of winding 2 to 2. The winding number ranges from 1 to 7, and 0 indicates an invalid winding number.For a non-multi-splittransformer, set the winding number to 0 by default.See the following figure.
Step 2 Set the box-type transformer number and winding number for all SUN2000s in the same PV array.
1. Log in to the SUN2000 app as an advanced user over Bluetooth or a data cable, and open the Settings screen.
2. For a multi-split transformer, further set the winding number of the corresponding box-type transformer, as shown in the following figure.
By now, the anti-crosstalk function is successfully set on the SUN2000.
