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 one of the following methods to identify
missing slaves and troubleshoot connectivity problems:

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.
