Page 8: Communication Address Setting
Communication Address Setting To enable DC MPLC communication, you need to set the communication addresses of the inverter units and PVS (combiner boxes) separately. Communication Topology The typology diagram of communication among the PVS, inverter unit, and smart communi- cation unit (SCU) is as shown in the figure below, with SG4400UD as an example. figure 3-1 Topology Diagram of Device Communication Set MPLC Master Node Address on DIP Switch Each inverter unit has a MPLC master node module. - Page 9 User Manual 3 Communication Address Setting Step 1 Open the cabinet door on the DC side of the inverter unit. The MPLC master node module is set on the cabinet door, as shown in the picture below.

User Manual 4 Operation on WEB Step 2 Configure the topological relationship between the master node and slave node. Click on the right, and enter the device information based on the actual connection be- tween the slave node and master node. For example, if a PVS slave node is connected to the Branch 2 port of the MPLC master node of inverter unit #4, set the parameters according to the figure below. - Page 16 4 Operation on WEB User Manual Step 1 Set the master node. Choose “System→Port Parameter→MPLC”. Select the master node, and click . Then, based on the on-site arrangement, enter the array ID in the pop-up dialog, and click “Next”.
