Creating An Rs485 Bus Connection - SolarEdge EV Series Installation Manual

66 Creating an RS485 Bus Connection
8. 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 above ( Figure 25 ).
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 Connection Unit with Safety Switch.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the
inverter cover is removed.
AVERTISSEMENT!
RISQUE D'ÉLECTROCUTION, ne touchez pas les fils non isolés lorsque le
couvercle de l'onduleur est retiré.
d. Configure the connection as described in Communication on page 45.
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)
11. Verify the connection, as described in Verifying the Connection on page 68.

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 as described on page 66.
