Chapter 7: Setting Up Communication Chapter 7: Setting Up Communication Power optimizers send information to the inverter via the DC power lines (the PV output circuit). The information is sent from the inverter to the SolarEdge monitoring portal through the Internet. In order to send the data from the inverter, a communication connection must be set up, as described in this chapter. Communication setup is not required for power harvesting, however is needed for using the SolarEdge monitoring portal. This chapter describes setting up communication between multiple inverterss for a master/slave configuration. CAUTION! When connecting the communication cables, make sure that the ON/OFF switch at the bottom of the inverter is turned OFF, and the AC is turned OFF. When configuring the communication parameters, make sure that the ON/OFF switch is OFF, and the AC is turned ON. Communication Types • Ethernet: used for a LAN connection • RS485: used for the connection of multiple SolarEdge devices on the same bus in a master-slave configuration. RS485 type can also be used as an interface to external non-SolarEdge devices, such as revenue meters and data loggers. • ZigBee: Optional wireless communication (purchased separately; refer to the supplied manual). • Wi-Fi: Optional wireless connection (purchased separately; refer to the supplied manual). Only communication products offered by SolarEdge are supported. Always connect the communication options when the inverter is OFF. Communication Connectors Two communication glands are used for connection of the various communication options. Each gland has three openings. The table below describes the functionality of each opening. Unused openings should remain sealed. 1 (PG16) Gland# Opening Functionality Cable Size (diameter) One small External antenna cable 2-4 mm Two large Ethernet connection (CAT5/6), ZigBee, or Wi-Fi 4.5-7 mm 2 (PG13.5) All three RS485, power reduction 2.5-5 mm SolarEdge-Installation Guide MAN-01-00057-3.1 55
Removing the Inverter Cover Figure 18: Communication Glands The communication board has a standard RJ45 terminal block for Ethernet connection, a 9-pin terminal block for RS485 connection, as shown below: Figure 19: Internal connectors Removing the Inverter Cover Use the following procedure for cover removal for communication connection purposes. 1. Turn the inverter ON/OFF switch to OFF. 2. Disconnect the AC to the inverter by turning OFF the circuit breakers on the distribution panel. Wait 5 minutes for the capacitors to discharge. 3. Open the inverter cover’s six Allen screws and carefully pull the cover horizontally before lowering it. CAUTION! When removing the cover, make sure not to damage internal components. SolarEdge will not be held responsible for any components damaged as a result of incautious cover removal. 56 SolarEdge-Installation Guide MAN-01-00057-3.1
