Pro Tip:

Check the aGate's cloud connection status by navigating to the "Network Status" page within the FranklinWH app. A successful connection will display the status as "Connected." If the status is "Disconnected" or intermittently connecting, focus troubleshooting efforts on network configuration and connectivity.

Recommended Action:

1

Reboot the aGate via the FranklinWH mobile app or web portal. Check the 'System' or 'Settings' menu for a 'Restart' or 'Reboot' option.
2

Verify the aGate's firmware is up-to-date. Navigate to the 'Firmware Update' section in the app and initiate an update if available. Ensure a stable internet connection during the update process.
3

Check the Wi-Fi signal strength in the FranklinWH app. If the signal is weak, relocate the aGate closer to the Wi-Fi router or install a Wi-Fi extender.
4

If Wi-Fi connectivity is unreliable, enable the cellular backup connection in the app's network settings.
5

Review the aGate's event log in the FranklinWH app or web portal for any error messages or warnings related to communication or power conversion.
6

If the noise persists, perform a factory reset of the aGate via the app, noting this will erase custom settings and require reconfiguration.
7

Contact FranklinWH support through the app or website with detailed information about the humming noise and steps taken.

What to Look For:

The FranklinWH aGate gateway is emitting a noticeable humming noise during backup mode operation in a residential setting. The system otherwise appears to be functioning, maintaining power to the designated critical loads panel.

Technical Background:

The aGate serves as the central communication and control hub for the FranklinWH energy storage system. It manages grid interaction, battery charging/discharging, and backup power functionality. Its internal processors manage complex algorithms for power conversion and system health monitoring, communicating wirelessly (Wi-Fi, Cellular) with the FranklinWH cloud platform and wired (Modbus/CAN) with other system components like batteries and inverters. Unexpected audible noise suggests a potential instability or anomaly in one of these communication or control loops.

Common Causes:

Inconsistent data synchronization between the aGate and the FranklinWH cloud platform during backup power events.
Firmware anomaly causing incorrect switching frequencies during DC-AC conversion.
Excessive network traffic or interference impacting Modbus communication with battery modules.
Corrupted configuration files leading to suboptimal system settings.
Wi-Fi connectivity issues causing repeated attempts to re-establish connection with the cloud.
Insufficient cellular signal strength causing the aGate to strain the cellular module during cloud communication attempts.

Maintenance Tips:

Regularly update the aGate's firmware to the latest version.
Monitor the system's performance through the FranklinWH app or web portal, paying attention to communication status and error logs.
Periodically check the Wi-Fi signal strength and ensure a stable internet connection.
Review and adjust the system's configuration settings as needed to optimize performance.
