Creating An Rs485 Bus Connection - SolarEdge Solar Inverter Installation Manual

Chapter 6: Setting Up Communication

Connect the Ethernet connector to the RJ45 plug on the inverter's communication board.
5
For the switch/router side, use a pre-crimped cable or use a crimper to prepare an RJ45
communication connector: Insert the eight wires into the RJ45 connector in the same order as in
Figure 17.
6
Connect the cable's RJ45 connector to the RJ45 port of the Ethernet switch or router. You can
connect more than one inverter to the same switch/router or to different switches/routers, as
needed. Each inverter sends its monitored data independently to the SolarEdge monitoring portal.
7
Inverters are configured by default to LAN. If reconfiguration is required:

Make sure the ON/OFF switch is OFF.

Turn ON the AC to the inverter by turning ON the circuit breaker on the main distribution panel.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the inverter cover is
removed.

Use the user buttons to configure the connection, as described in Communication on page 33.
NOTE:
If your network has a firewall, you may need to configure it to enable the connection to the
following address:

Destination Address: prod.solaredge.com

TCP Port: 22222 (for incoming and outgoing data)
8
Verify the connection, as described in Verifying the Connection on page 48.

Creating an RS485 Bus Connection

The RS485 option enables creating a bus of connected inverters, consisting of up to 31 slave inverters and
1 master inverter. Using this option, inverters are connected to each other in a bus (chain), via their RS485
connectors. The first and last inverters in the chain must be terminated.
The following sections describe how to physically connect the RS485 bus and how to configure the bus.
►
To connect the RS485 communication bus:
1
Remove the inverter cover as described in Removing the Inverter Cover on page 42.
2
Remove the seal from one of the openings in communication gland #2 and insert the wire through
the opening.
