Rs485 Bus Configuration; Verifying The Connection - SolarEdge Delta SE12.5K Installation Manual

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 via the LAN option (refer to ) or any
of the other options.
To configure the RS485 bus:
All inverters are configured by default as followers. To configure the leader:
1. Verify the ON/OFF/P switch is OFF.
2. Verify that AC is on.
