How to fix communication issues with my SolarEdge Controller?
- JJanet FlemingJul 28, 2025
If your SolarEdge Controller's LCD inverter displays an asterisk (*) next to the Device type, or SetApp inverters show a 'Not connected' error, or the number of detected devices doesn't match the number of communicating devices, and the blue LED is OFF, it indicates the device isn't associated with the inverter. Try turning the device OFF and then ON, and recheck communication. If that doesn't work, turn the device OFF, remove it from the Device Manager screen, and repeat the discovery process. Note that reconfiguration may be required. If the problem persists, contact SolarEdge support.
