Learn why the Tesla Gateway 2 shows a red LED for site communication interruption and how to fix it.
The red LED indicates a communication issue between the Gateway and the site. This can be due to network problems or device malfunctions.
Check your internet connection and ensure the Gateway is properly connected to the network. Restarting the device may also help resolve the issue.
The Gateway serves as the communication hub between the solar inverter and the Tesla app, relaying performance data and alerts. A 'Site Communication Interrupted' fault typically signifies that the Gateway is unable to establish or maintain a connection with the inverter or the local network. This can occur due to various electrical issues, such as poor insulation resistance (RISO) measurements, ground fault detection triggering, or grid frequency limits being exceeded, which may cause the inverter to enter a protective state.
Only a licensed electrician or certified solar installer should perform troubleshooting or repairs on the electrical components of the solar system to ensure compliance with safety standards and regulations.
To avoid future communication interruptions, ensure that the Gateway is installed in a location with strong Wi-Fi signal and minimal interference. Regularly check and maintain all wiring connections, and keep firmware updated. Schedule routine inspections of the solar system components to identify and rectify any potential issues early.
