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.
5
If you are using a ZigBee connection and there is interference on the channel
being used, then change the channel.
