Creating An Rs485 Bus Connection - SolarEdge SE8K-N4 Installation Manual

7. 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.
NOTE
There are no LED indicators on the Ethernet connector, if the inverter is not communicating with
the monitoring platform through a LAN refer toTroubleshooting Communication on page 71.
8. The inverter is configured by default to LAN. If r econfiguration is required:
a. Verify the ON/OFF switch is OFF.
b. Verify the AC is on.
c. Close the cover and turn ON the Connection Unit.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the Connection Unit
cover is removed.
d. Use the SolarEdge SetApp to access the Commissioning main menu screen as described in
Communication on page 40.
e. From the main menu tap Communication. The Communication screen is displayed:
f. Select the following to configure the connection:
Server è LAN
l
LAN è DHCP è Enable
l
9. Verify the connection, as described in Verifying the Connection on page 65.
NOTE
The system automatically establishes communication with the monitoring platform as it is
configured to LAN by default.
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
Modbus TCP Port: 22222 (for incoming and outgoing data)

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, thus allowing to connect only the master inverter to the monitoring platform. The first and
last inverters in the chain must be terminated as described in RS485 Bus Configuration on page 64
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a shielded Ethernet cable (Cat5/5E STP) may be used)
l
Wire cross-section : 0.2- 1 mm²/ 24-18 AWG
l
Maximum distance between first and last devices: 1 km /3300 ft.
l
The following sections describe how to physically connect the RS485 bus and how to configure the bus.
