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
in the RS485 chain; make sure the grounding wire is not in contact with other
wires. Connect the grounding wire to the grounding bus-bar in the
Connection Unit with Safety Switch.
To connect to the monitoring platform:
1. Designate a single inverter as the connection point between the RS485 bus and the
monitoring platform. This inverter will serve as the master inverter.
2. Connect the master to the monitoring platform via the LAN option (refer to
Creating
an Ethernet (LAN) Connection
on page 63) or any of the other options.
To configure the RS485 bus:
All inverters are configured by default as slaves. To configure the master:
1. Verify the ON/OFF/P switch is OFF.
2. Verify that AC is on.
3. Use SetApp to access the Commissioning menu screen as described in
Communication
on page 45.
4.
From the Commissioning menu tap Communication. The Communication screen is
displayed.
5.
Select the following to configure the connection:
