6. For creating an RS485 bus - connect all B, A and G pins in all inverters. The following figure shows this
connection schema:
NOTE
Do not cross-connect B, A and G wires. Do not insert wires into RS485- 2 pins.
7. Tighten the terminal block screws.
8. Check that the wires are fully inserted and cannot be pulled out easily.
9. Push the RS485 terminal block firmly all the way into the connector on the right side of the
communication board.
10. Terminate the first and last SolarEdge device (inverter/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
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).
