NOTE
Only the first and last SolarEdge devices in the chain should be
terminated. The other devices in the chain should have the termination
switch OFF.
To configure the RS485 communication bus with SolarEdge inverters:
By default, all SolarEdge devices are pre-configured as slaves on the RS485-1 port.
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 SolarEdge device may be
the master (Firefighter Gateway, inverter). If you connect the installation to the
SolarEdge monitoring platform, the device used to connect to the server must be the
master.
The following describes how to configure the master device.
