Solar Edege manufacturer gives detailed information on how to connect multiple inverters with different options on the link: https://knowledge-center.solaredge.com/sites/kc/files/solaredge-communication_options_application_note_v2_250_and_above.pdf.

1.1 Physical connection between Reduxi and inverter

Connect Reduxi controller to contacts on the circuit of the inverter as displayed in the image below:

2. BUS (serial) connection configuration for master and slave inverters

This example is given to simplify users' experience on how to create a serial connection between different inverters where one acts as a master and others as slaves and a

The image below displays one BUS connection with RS485 from slaves to a master, which is secondarily connected to the internet.

2.1 Settings for slave devices

Once the physical connections are established, the addresses for salves must be defined. The following images give instructions for salve address settings:

• Open inverter interface

• Open Site communication

• Open RS485-2

• Open protocol

• Select SunSpec (Non-SE logger and define Device ID

3. Connections for the Master inverter to the Reduxi controller via TCP

On how to connect the Master inverter via Modbsu TCP with a defined IP address to the Reduxi controller, please follow the link: SolarEdge Master Configuration.

Image of example for Modbus TCP setting on site of the Reduxi controller:

4. Connections for the Master inverter to the Reduxi controller via RTU.

It is possible to establish a connection from the Master inverter to the Reduxi controller also via a serial connection (Modbus RTU). 

Configuration of salves inverters is the same as in point 2.1 Settings for slave devices.

Image of example for Modbus RTU setting on site of the Reduxi controller:
