SolarEdge App: Unauthorized Site Access After Password Change

Troubleshoot SolarEdge app 'Unauthorized Site Access' after password change. Check network, firmware, and cloud sync for residential solar systems.

Frequently Asked Questions

•How do I update the firmware on my SolarEdge gateway?

Firmware updates are typically performed automatically over the air (OTA). You can check for available updates in the SolarEdge monitoring portal or via the mobile app. If an update is available, follow the on-screen instructions to initiate the update process. Ensure the gateway has a stable internet connection during the update.

•What is the default username and password for the SolarEdge gateway?

The default username and password are not public. Consult the SolarEdge installation manual or contact SolarEdge support to obtain the correct credentials if needed. These credentials are typically required for advanced configuration and are not needed for standard user access.

•How do I enable two-factor authentication for my SolarEdge account?

Two-factor authentication can be enabled through the SolarEdge monitoring portal. Navigate to your account settings and look for the security or authentication options. Follow the instructions to set up two-factor authentication using your preferred method (e.g., authenticator app or SMS).

What to Look For:

SolarEdge monitoring app displays "Unauthorized Site Access" error message following a password change. The user is unable to access system data or control settings via the app. Connectivity to the SolarEdge monitoring portal via web browser may or may not be affected.

Safety Warning:

Do not attempt to physically disassemble or modify the SolarEdge gateway or any other solar equipment. Improper handling can result in electrical shock or damage to the system. Always use strong and unique passwords to protect your system from unauthorized access. Report any suspicious activity to SolarEdge support immediately. Ensure all password-related information is securely stored. Prior to any work, activate the DC disconnect and follow NEC 690.12 rapid shutdown procedures.

Recommended Action:

1

Force close the SolarEdge monitoring app and restart it. This clears any cached credentials.
2

Verify internet connectivity on your home network. Ensure the SolarEdge gateway has a stable connection.
3

Check for firmware updates for the SolarEdge gateway via the web portal (if accessible) or through the app (if partially functional). Update to the latest version.
4

Clear the app's cache and data in your phone's settings (Android) or offload the app (iOS) to remove temporary files. Note that offloading the app on iOS is preferable to deleting the app since it retains your settings.
5

If using cellular backup, ensure the cellular connection is active and that the SolarEdge gateway is configured to use it if the primary internet connection fails.
6

Perform a soft reset of the SolarEdge gateway by cycling its power (if accessible and safe to do so) after disconnecting the DC disconnect (AC only if ESS is installed) . Allow several minutes for the gateway to reboot and re-establish connection with the cloud.
7

Re-enter your new password in the SolarEdge app and attempt to log in. If the issue persists, contact SolarEdge support for further assistance.

Technical Background:

The SolarEdge monitoring system relies on a secure connection between the residential gateway, the SolarEdge cloud server, and the user's mobile app. Password changes initiate a re-authentication process. Issues can arise from cached credentials, synchronization delays between the app and the cloud, or network connectivity problems preventing successful re-authentication. The gateway uses Modbus TCP for local communication and encrypted protocols (HTTPS) for cloud communication. Interruption in these protocols will result in authentication errors.

Common Causes:

App caching old credentials after a password change.
Synchronization delay between the SolarEdge cloud server and the local gateway.
Intermittent network connectivity issues preventing successful re-authentication with the cloud.
Outdated firmware on the SolarEdge gateway causing authentication incompatibility.
Corrupted app data requiring a reset or resystem.
Incorrect site ID configured within the app after password reset.
