Power Optimiser Troubleshooting - SolarEdge Energy Bank Installation Manual

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.
