Learn why your Tesla Gateway 3 shows 'Site Communication Interrupted' and how to fix it.
Storms can disrupt internet connectivity or damage communication lines, affecting system performance.
Check your internet connection, reset the Gateway, and ensure all cables are secure.
The Tesla Gateway 3 is designed to monitor and manage communication between the solar inverter and the Utility Grid. When communication is interrupted, it may trigger a fault due to the loss of real-time data transmission. This can result from a variety of electrical logic issues, such as RISO (Insulation Resistance) measurements falling below acceptable thresholds, or ground fault detection activating due to moisture intrusion. Additionally, fluctuations in grid frequency during storms can cause the inverter to shut down to protect the system from damage.
After a storm, users may notice that the Tesla Gateway 3 displays a red LED indicator or a notification in the Tesla app indicating 'Site Communication Interrupted'. This may be accompanied by a significant drop in solar production metrics, with the monitoring app showing no data or delayed updates.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical components to ensure safety and compliance with local codes.
