Troubleshooting RS485 Communication

1. If the message Master Not Found appears, check the connections to the master device and fix if
required.
2. If after slave detection the number of slaves displayed in the master under RS485-X Conf è Slave
Detect is smaller than the actual number of slaves, use the slave list to identify missing slaves and
troubleshoot connectivity problems:
a. Select RS485-X Conf è Slave List. A list showing the serial numbers of the detected slaves i s
displayed.
b. To view the details of a detected slave device, select its serial number entry.

If this device is detected for the first time after the master wakeup, N/A appears for this
information.

Additional Troubleshooting

1. Check that the modem or hub/router is functioning properly.
2. Check that the connection to the internal connector on the communication board is properly done.
3. Check that the selected communication option is properly configured.
4. Use a method independent of the SolarEdge device to check whether the network and modem are
operating properly. For example, connect a laptop to the Ethernet router and connect to the
Internet.
5. Check whether a firewall or another type of network filter is blocking communication.
