NOTE
Only the first and last SolarEdge devices in the chain should be terminated.
The other inverters in the chain should have the termination switch OFF
(down position).
RS485 Bus Configuration
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 leader inverter.
2. Connect the leader to the monitoring platform using Ethernet (refer to
Creating an
Ethernet (LAN) Connection above).
To configure the RS485 bus:
All inverters are configured by default as followers. To configure the leader:
1. Make sure the inverter's ON/OFF/P switch is off.
2. Make sure that the AC circuit breaker on the main distribution panel is on.
3. Turn on the DC Safety Unit (if applicable).
4. Access SetApp, as described in
5. From the
Commissioning
screen, select
Site Communication > RS485-12 >
Protocol > SolarEdge > SolarEdge Leader
.
6. Return to the
RS485-12
screen and select
Follower Detect.
The system starts automatic detection of the follower inverters connected to the
leader inverter. The inverter should report the correct number of followers. If it does
not, verify the connections and terminations in all inverters in the chain.
7. To check the follower IDs and last communication time, select
RS485-12
>

8. Verify the connection of the leader to the monitoring platform, as described below.
Verifying the Connection
After connecting and configuring a communication option, perform the following
steps to check that the connection to the Monitoring platform has been successfully
established.
1. If the Synergy Manager cover is not closed, close it: Attach the cover and secure it
by tightening the screws with a torque of 10.3 N*m / 7.6 lb.*ft. For proper sealing,
