Verifying The Connection; Troubleshooting Communication - SolarEdge SE3000 Installation Manual

Verifying the Connection

►
To verify the connection:
1
Verify that the DC circuit breaker is OFF.
2
Verify that the inverter's ON/OFF switch is still OFF.
3
Turn ON the AC to the inverter by using the circuit breakers on the main
circuit board.
4
Wait for the inverter to connect to the SolarEdge Monitoring Server. This
may take up to two minutes.
5
Verify that the LCD panel displays a window similar to the following:
V a c [ v ]
2 3 0 . 7
P _ O K :

S_OK: Verify that S_OK appears on the panel to indicate a functioning
connection to the SolarEdge Monitoring Server, which was validated
during the last two minutes.
NOTE:
If the S_OK indication is not displayed, then perform the following:

Use another method (unrelated to the SolarEdge inverter) to check
whether the network and modem are operating properly. For example,
connect a laptop to the Ethernet modem and connect to the Internet.

Check whether a firewall or another device is blocking transmission.

Check the configuration of the inverter.

Troubleshooting Communication

►
To troubleshoot a communication problem:
1
Check that the modem or hub/router is functioning properly.
2
Check that the connection to the internal connector on the inverter board is
performed properly through its gland at its bottom.
3
Check that the selected communication option (RS232, Ethernet [LAN],
RS485 or ZigBee) is configuring properly using the inverter's LCD panel.
4
Check whether a firewall or another type of network filter is blocking
communication.
