Symptoms:

aGate displays Error 6003. System fails to synchronize with the FranklinWH cloud. Energy monitoring data is unavailable in the app. Backup power functionality may be impaired. Intermittent or complete loss of communication with battery modules.

Pro Tip:

Access the aGate's advanced settings menu (if available in the app or through the installer portal) to view detailed system logs and diagnostic information. This may provide further insight into the cause of Error 6003. Check the API status from the installer portal to ensure proper cloud communication is established. If there is a problem with cloud connection, this will cause Error 6003.

Possible Causes:

Corrupted firmware preventing proper power supply initialization.
Network connectivity issues preventing successful cloud synchronization.
Over-the-air (OTA) update failure leaving the system in an unstable state.
Configuration error within the aGate's network settings.
Incompatibility with the homeowner's network configuration (DHCP issues, firewall restrictions).
Outdated mobile app version causing communication problems with the aGate.

Important Warnings:

Do NOT attempt to open or repair the aGate's internal components. Error 6003 could indicate an internal component failure. Improper handling could result in electric shock or further damage to the unit. Ensure all app accounts have strong, unique passwords and enable two-factor authentication where available. Do not share login credentials with unauthorized individuals. Regularly review user access permissions to prevent unauthorized system control.

Recommended Action:

1

Power cycle the aGate via the DC disconnect switch following NEC rapid shutdown procedures. Wait 5 minutes before restoring power.
2

Verify that the aGate is connected to the internet via Wi-Fi or Ethernet. Check the network settings in the FranklinWH app.
3

Ensure that the FranklinWH app is updated to the latest version from the app store.
4

Check the aGate's firmware version in the app and update to the latest version if available.
5

Perform a network reset via the app (if option is available) and reconfigure the Wi-Fi settings.
6

If using cellular backup, ensure the SIM card is properly installed and activated with the carrier.
7

Contact FranklinWH support if the error persists after these steps.

Technical Background:

The aGate's internal power supply provides regulated DC voltage to its communication and control circuits, including Wi-Fi/Ethernet modules, cellular modem (if equipped), Modbus/CAN bus interfaces, and the main processor. Error 6003 indicates a failure in voltage regulation, filtering, or overall power delivery within this subsystem. This can disrupt data acquisition, processing, and transmission to the cloud and the local monitoring app. Firmware updates and configuration changes may also fail.

Maintenance Tips:

Regularly check for firmware updates for the aGate via the FranklinWH app
Ensure a stable and reliable internet connection
Periodically review network configuration settings in the app
Monitor the aGate's performance and data logging history through the FranklinWH app for any anomalies
Check the health of the cellular backup connection, if enabled
