61 Creating an RS485 Bus Connection
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/lightning_surge_
protection.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. For inverters with a Connection Unit with Safety Switch, 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 57) 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 39.
4. From the Commissioning menu tap Communication. The Communication screen is
displayed.
5. Select the following to configure the connection:
Server è LAN, Cellular or Wi-Fi
RS485-2 è Protocol è SolarEdge èSolarEdge Master
RS485-2 è Slave Detect
The system starts automatic detection of the slave inverters connected to the master
inverter. The inverter should report the correct number of slaves. If it does not, verify
the connections and terminations.
