Critical Safety Precautions:

Do not attempt to open or repair the PWRview gateway. This could void the warranty and create a safety hazard. Ensure proper password management and enable two-factor authentication (if available) to protect against unauthorized access to the system. Regularly review user permissions and revoke access for former installers or maintenance personnel. Monitor network security and apply appropriate firewall settings to prevent external intrusions.

Symptoms:

The Generac PWRview gateway is unexpectedly rebooting, leading to intermittent loss of monitoring data, control functionality within the mobile application, and potential disruption of grid services or backup power operation.

Solution:

1

Verify network connectivity: Check Wi-Fi signal strength or ethernet cable connection. Ensure the router is functioning correctly and has internet access.
2

Check for firmware updates: Use the PWRview mobile app to check for and install any available firmware updates for the gateway.
3

Clear app cache and data: In the mobile device settings, clear the PWRview app's cache and data to resolve potential software conflicts.
4

Reboot the gateway manually: If possible, use the app to remotely reboot the gateway. Allow sufficient time for the reboot process to complete.
5

Review event logs: Access the PWRview portal (if available through installer login) to review event logs for specific error messages or patterns.
6

Reset network settings: Use the PWRview app to reset the gateway's network settings and reconfigure the Wi-Fi or ethernet connection.
7

Contact Generac support: If the problem persists, contact Generac support for further assistance and potential hardware replacement.

How It Works:

The PWRview gateway acts as the central communication hub for the solar and storage system. It collects data from inverters, batteries, and the grid meter via Modbus TCP/IP or CAN bus protocols. This data is then transmitted to the Generac cloud for monitoring and control purposes via a Wi-Fi or ethernet connection. A watchdog timer is implemented in the gateway firmware to automatically reboot the system in case of software errors or unresponsive processes. Frequent reboots indicate an instability in the firmware, network communication issues, or data processing errors.

Pro Tip:

Note the frequency and timing of the reboots. Correlate the reboots with specific events, such as grid outages, inverter operation, or app usage. This may provide valuable clues for diagnosing the underlying cause. Check the PWRview event logs via installer login for diagnostic codes related to communication failures.

Possible Causes:

Corrupted firmware due to interrupted over-the-air (OTA) updates.
Network connectivity issues (Wi-Fi signal strength, ethernet cable problems, router misconfiguration) causing intermittent data loss and gateway instability.
Data synchronization errors between the gateway and the cloud server leading to software lockups.
Overheating of the gateway due to poor ventilation.
Incompatible software versions between the mobile app and the gateway firmware.
Modbus communication errors with connected inverters or batteries.

Maintenance Tips:

Regularly check for and install firmware updates via the mobile app
Ensure stable network connectivity by using a dedicated Wi-Fi network or a wired ethernet connection
Periodically clear the app cache to prevent data corruption
Monitor the gateway's operating temperature and ensure adequate ventilation
Consider enabling automatic firmware updates (if available)
