► To configure the RS485 communication bus with SolarEdge inverters/SMI:
By default, all SolarEdge devices are pre-configured as slaves. Slaves can be further configured using the
RS485-x Conf option in the Communication menu.
One device must be set as the master on the RS485 bus. Any one of the SolarEdge devices may be the
master (firefighter gateway, inverter, or SMI). If you connect the installation to the SolarEdge monitoring
portal, the device used to connect to the server must be the master.
The following describes how to configure the master device.
