Creating An Rs485 Bus Connection - SolarEdge storedge Installation Manual

Creating an RS485 Bus Connection

7. 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 35).
8. 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.
9. The inverter is configured by default to LAN. If r econfiguration is required:
a. Make sure the ON/OFF 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 StorEdge Connection Unit.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the inverter cover is
removed.
RISQUE D'ÉLECTROCUTION, ne touchez pas les fils non isolés lorsque le couvercle de
l'onduleur est retiré.
d. Use the internal user buttons to configure the connection, as described in Communication on
page 58.
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
l
TCP Port: 22222 (for incoming and outgoing data)
l
10. Verify the connection, as described in Verifying the Connection on page 77.
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.
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a 4-wire cable may be used)
l
Wire cross-section area: 0.2- 1 mm²/ 24-18 AWG (a CAT5 cable may be used)
