Installation Guide

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:
https://www.solaredge.com/sites/default/files/overvoltage_surge_
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
