Generac PWRview: False Grid Export Displayed Without Smart Meter

Troubleshoot Generac PWRview showing grid export when no smart meter is installed. Resolve incorrect data reporting with configuration and software updates.

Frequently Asked Questions

•How do I verify the CT configuration in the PWRview app?

Navigate to the 'Devices' or 'Settings' section in the app, then select the PWRview meter. Look for options related to CT configuration, such as 'Number of CTs' or 'CT Assignment'.

•What is the latest firmware version for the PWRview Gateway?

The latest firmware version can be found in the PWRview app under the device settings or by contacting Generac support. The update process is typically automated through the app.

•How can I check the Wi-Fi signal strength to the PWRview Gateway?

The PWRview app may display the Wi-Fi signal strength in the device settings. Alternatively, you can use a Wi-Fi analyzer app on your smartphone to measure the signal strength near the gateway.

Technical Overview:

The PWRview system relies on current transformers (CTs) to measure current flow and calculate power import/export. Data is aggregated by the PWRview Gateway, which transmits information to the Generac cloud via Wi-Fi or ethernet. Incorrect CT configuration, gateway firmware errors, or cloud synchronization issues can lead to misinterpretation of energy flow and false reporting of grid export. Communication relies on Modbus TCP/IP protocol.

Critical Safety Precautions:

Ensure all work is performed according to local electrical codes. Prioritize data security by using strong, unique passwords for your Generac account and Wi-Fi network. Regularly review user permissions within the Generac portal and revoke access for any unauthorized users. Never share your login credentials.

Solution:

1

Verify the CT configuration within the PWRview app. Ensure the correct number of CTs are selected and that they are assigned to the proper service conductors (grid, solar, load).
2

Check the Wi-Fi or ethernet connection of the PWRview Gateway. Ensure a stable internet connection for reliable data transmission.
3

Update the PWRview Gateway firmware to the latest version via the PWRview app. Firmware updates often include bug fixes and improved data processing algorithms.
4

Clear the PWRview app cache and data, then restart the app. This can resolve temporary data synchronization issues.
5

Cycle power to the PWRview Gateway by switching the dedicated breaker OFF for 30 seconds, then back ON. This will reset the gateway and re-establish the connection to the cloud.
6

Review the meter configuration within the PWRview app's settings. Confirm that the system is set up as "No Smart Meter" or a similar designation.
7

Contact Generac support if the issue persists, providing detailed screenshots of the app's configuration and energy data.

Symptoms:

The Generac PWRview monitoring system incorrectly displays grid export data, even though a smart meter is not installed at the residential site. This results in inaccurate energy usage and production reporting within the PWRview app and cloud portal.

Pro Tip:

Access the advanced settings menu in the PWRview app (if available) by tapping the version number multiple times. This may reveal hidden diagnostic commands or configuration options.

Common Causes:

Maintenance Tips:

Regularly update the PWRview Gateway firmware to the latest version
Periodically review the system's configuration within the PWRview app to ensure accuracy
Monitor the Wi-Fi signal strength to the gateway and ensure a stable internet connection
Check for and apply app updates as they are released
