To connect to the server:
1
Designate a single inverter as the connection point between the RS485 bus and the SolarEdge
monitoring server. This inverter will serve as the master inverter.
2
Connect the master to the SolarEdge monitoring server via one of the communication options.
►
To configure the RS485 communication bus:
1
All inverters are preconfigured as slaves. To configure the inverter designated as master, select the
following in the LCD menus:
Communication
RS485-1 Conf.
Device Type
SolarEdge
RS485-1 Conf.
Protocol
Master
RS485-1 Conf.
Slave Detect
The system starts automatic detection of the SolarEdge slave inverters connected to the master
inverter. The inverter should report the correct number of slaves. If it does not, verify the
connections and terminations.
2
Verify the connection of the master to the SolarEdge monitoring server, as described in
Verifying the
Connection
below.
