Chapter 6: Setting Up Communication
Power optimizers send information to the inverter via the DC power lines (the PV output circuit). No
additional wires or configurations are required for this purpose. The information is then 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 and is needed only for using the SolarEdge monitoring portal.
This chapter also describes setting up communication between multiple inverters 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 Connectors
Two communication glands are used for connection of the various inverter communication options. Each
gland has three openings. The table below describes the functionality of each opening. Unused openings
should remain sealed.
Ethernet connection (CAT5/6) or RS232

Two types of communication boards are available, different in the Ethernet connector: one with an 8-pin
terminal block connection and the other with a standard RJ45 Ethernet connector, as shown below:
