Creating An Rs485 Bus Connection - SolarEdge StorEdge Solution with Backup Installation Manual

104 Creating an RS485 Bus Connection
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. Use the internal user buttons to configure the connection, as described in
Communication on page 80.
NOTE
If your network has a firewall, you may need to configure it to enable
the connection to the following address:
Destination Address: prod2.solaredge.com
TCP Port: 22222, 22221, or 80 (for incoming and outgoing data)
10. Verify the connection, as described in Verifying the Connection on page
108. Verifying the Connection on page 108.

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 107.
RS485 wiring specifications:
Cable type: Min. 3-wire shielded twisted pair (a shielded Ethernet cable (Cat5/5E
STP) may be used)
Wire cross-section area: 0.2- 1 mm²/ 24-18 AWG (a CAT5 cable may be used)
Maximum nodes: 32
Maximum distance between first and last devices: 1 km /3300 ft.
NOTE
If using a cable longer than 10 m/33 ft in areas where there is a
risk of induced voltage surges by lightning, it is recommend to
use external surge protection devices. For details refer to:

protection_na.pdf
If grounded metal conduit are used for routing the communication wires, a
lightning protection device is not required.
If not using surge protection, connect the grounding wire to the first inverter
.
