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 on the DC Safety Unit .
4. Access SetApp, as described in Communication on page 50.
5. From the Commissioning screen, select Site Communication > RS485-1 > Protocol
> SolarEdge > SolarEdge Leader.
6. Return to the RS485-1 screen and select Follower Detect.
