Chapter 7: Setting Up Communication
10. Terminate the first and last SolarEdge device (inverter/SMI/Control and communication
gateway, etc.) in the chain by switching a termination DIP-switch inside the inverter to ON
(move the switch up). The switch is located on the communication board and is marked
SW7.
NOTE
Figure 27: RS485 termination switch
Only the first and last SolarEdge devices in the chain should be terminated. The other
inverters in the chain should have the termination switch OFF (down position).
To connect to the monitoring portal:
1. Designate a single inverter as the connection point between the RS485 bus and the
SolarEdge monitoring portal. This inverter will serve as the master inverter.
2. Connect the master to the SolarEdge monitoring portal via the LAN or ZigBee
communication option.
To configure the RS485 communication bus:
All inverters are configured by default as slaves. If reconfiguration is required:
1. Make sure the ON/OFF switch is OFF.
2. Turn ON the AC to the inverter by turning ON the circuit breaker on the main distribution
panel.
WARNING!
ELECTRICAL SHOCK HAZARD. Do not touch uninsulated wires when the inverter
cover is removed.
