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.
Configure the connection as described in
Communication
on page 37.
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)
10. Verify the connection, as described in
Verifying the Connection
on page 1.
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.
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 recommended
to use external surge protection devices. For details refer to:
https://www.solaredge.com/sites/default/files/lightning_
surge_protection.pdf.
If grounded metal conduits 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
in the RS485 chain; ensure it is not in contact with other wires. For inverters
