Pro Tip:

In the Generac PWRcell app, navigate to the “Settings” or “Device Info” section to check the communication status between the PWRview gateway and the CTs. Look for any error messages or abnormal readings. This can help isolate issues related to CT connectivity or configuration.

Possible Causes:

Incorrect CT placement or configuration within the PWRview app.
Communication errors between the CTs and the PWRview gateway.
Synchronization issues between the PWRview gateway and the Generac cloud.
Firmware bugs in the PWRview gateway causing miscalculation of energy flow.
Incorrect site configuration within the PWRview app (e.g., home load profile).
App version out of sync with gateway firmware, causing data interpretation errors.

Technical Background:

The PWRview system relies on current transformers (CTs) to measure current flow in and out of the home and the solar array. These measurements are processed by the PWRview gateway, which then transmits the data to the Generac cloud servers. The app displays the processed data. Errors in CT readings, gateway processing, or cloud synchronization can lead to incorrect reporting of grid import.

Critical Safety Precautions:

Data security is crucial. Secure your Wi-Fi network with a strong password. Regularly change the password of your Generac PWRcell account. Protect your account from unauthorized access to prevent manipulation of system settings and potential energy theft.

Recommended Action:

1

Verify CT placement and orientation according to the Generac system manual. Double-check that the CTs are measuring the correct circuits (solar, grid, load).
2

Check the PWRview gateway's network connectivity. Ensure it is connected to the internet via Wi-Fi or Ethernet.
3

Cycle power to the PWRview gateway by switching off the corresponding breaker in the electrical panel for 60 seconds and then turning it back on. Observe the gateway LEDs for normal operation.
4

Check for available firmware updates for the PWRview gateway via the Generac PWRcell app. Install any pending updates.
5

Review the site configuration within the PWRview app, paying close attention to the home load profile and solar array size. Recalibrate if necessary.
6

Clear the app cache and data, or uninstall and reinstall the Generac PWRcell app on your mobile device.
7

Contact Generac customer support if the issue persists after performing the above steps. Provide detailed information about the system configuration and the observed behavior.

Symptoms:

The Generac PWRview system reports energy import from the grid despite sufficient solar power generation and battery state of charge (SOC) capable of supplying the home's load.

Maintenance Tips:

Regularly check for and install firmware updates for the PWRview gateway and app.
Periodically review the site configuration within the PWRview app to ensure accuracy.
Monitor the PWRview gateway's network connectivity to ensure continuous data synchronization.
Every 6 months, power cycle the PWRview gateway to refresh the system.
