Creating An Rs485 Bus Connection - SolarEdge StorEdge Installation Manual

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 38.
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
TCP Port: 22222 (for incoming and outgoing data)
11. Verify the connection, as described in Verifying the Connection on page 62.

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 61.
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; make sure the grounding wire is not in contact with other
wires. For inverters with a Connection Unit, connect the grounding wire to the
grounding bus-bar in the Connection Unit.
