Huawei Alarm 2100 App Communication Certificate... | solarfaults.org

Technical Background:

The Huawei Alarm 2100 relies on a secure communication protocol to interact with the inverter and the monitoring app. This protocol often involves the use of digital certificates that authenticate the connection. When the certificate expires, the inverter may trigger a fault state to prevent unauthorized access or data breaches. This is a vital security measure to ensure that only verified devices can communicate with the inverter, safeguarding the system from potential cyber threats. Additionally, if the inverter detects issues with internet connectivity or firmware compatibility, it may also trigger alerts to ensure proper operation within the defined parameters.

Symptoms:

Users may notice alerts in the Huawei monitoring app indicating that the communication certificate for the Alarm 2100 is nearing expiration or has expired. Additionally, the inverter may display an error code or warning LED pattern, such as a blinking red LED indicating a fault. The app may also show a drop in energy production data or an inability to access real-time monitoring features.

Possible Causes:

Expired communication certificate due to time-limited authentication settings.
Inconsistent internet connectivity affecting app communication with the inverter.
Firmware mismatch between the Huawei Alarm 2100 and the monitoring app.
Incorrect network settings or credentials in the monitoring app.
Firewall settings or network security protocols blocking communication.
Power supply issues affecting the Alarm 2100 unit itself.

Solution:

1

Verify the current status of the communication certificate through the Huawei monitoring app or web portal.
2

If expired, log into the Huawei support portal to renew the communication certificate following their guidelines.
3

Check the inverter's firmware version and ensure it matches the required version for the Alarm 2100; update if necessary.
4

Confirm that the Alarm 2100 is connected to a stable internet connection; troubleshoot any network issues.
5

Review and adjust any firewall settings or network security protocols that may be hindering communication.
6

Power cycle the Alarm 2100 by disconnecting it from the power source for at least 10 seconds and reconnecting it to reset the system.
7

Test the connection again using the app to ensure communication is re-established.

Safety Warning:

Always ensure that troubleshooting and repairs are performed by a licensed electrician or certified solar installer to maintain safety and compliance with local codes.

Prevention:

To prevent future issues, regularly check the expiration dates of communication certificates and schedule renewals accordingly. Maintain firmware updates for both the inverter and the Alarm 2100 to ensure compatibility. Additionally, establish a reliable internet connection and periodically review network settings to prevent disruptions.
