Creating an RS485 Bus Connection

9. Connect the cable 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 platform.
10. The inverter is configured by default to LAN. If reconfiguration is required:
a. Make sure the ON/OFF/P switch is OFF.
b. Turn ON the AC to the inverter by turning ON the circuit breaker on the main
distribution panel.
c. Turn ON the Safety Switch.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the
inverter cover is removed.
d. Configure the connection as described in Communication on page 42.
NOTE
If your network has a firewall, you may need to configure it to enable
the connection to the following address:
Destination Address: prodssl.solaredge.com
TCP Port: 443 (for incoming and outgoing data)
11. Verify the connection, as described in Verifying the Connection on page 60.
Creating an RS485 Bus Connection
The RS485 option enables creating a bus of connected inverters, consisting of up to 31
follower inverters and 1 leader 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 as described on page 59.
