What to Look For:

The Generac PWRview app displays a yearly total production value that deviates significantly (more than 10%) from expected values based on previous years' data or utility bills. The daily and monthly production data may appear accurate, while the yearly total is skewed.

Technical Recommendation:

Some PWRview gateways have a hidden diagnostic menu accessible through a specific sequence of taps or swipes within the app. Consult the Generac support documentation or online forums for the activation sequence for advanced diagnostics, focusing on network and cloud connectivity status.

Important Warnings:

Do not attempt to disassemble or repair the PWRview gateway. Unauthorized modifications can void the warranty and potentially damage the equipment. Ensure all user accounts associated with the PWRview system utilize strong, unique passwords to protect against unauthorized access.

Possible Causes:

Inconsistent data reporting from the inverter to the PWRview gateway due to Modbus communication errors.
Cloud synchronization issues between the PWRview gateway and the Generac cloud servers.
Incorrect date or timezone settings on the PWRview gateway, leading to miscalculation of yearly totals.
Firmware bugs within the PWRview gateway affecting data aggregation.
Corruption of historical data stored on the Generac cloud servers.
App software glitches.

Recommended Action:

1

Verify the PWRview gateway's internet connection and confirm successful communication with the Generac cloud.
2

Check the date and timezone settings within the PWRview app and on the PWRview gateway (if accessible via web interface or advanced settings). Correct if necessary.
3

Force a data synchronization within the PWRview app (if available) to ensure the latest data is pulled from the Generac cloud.
4

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

Check for firmware updates for the PWRview gateway via the app or web interface (if available) and install the latest version.
6

If available, review the inverter's production data directly through the inverter's monitoring portal to compare against the PWRview data.
7

Contact Generac customer support to report the issue and provide details on the observed discrepancies. Request a review of the cloud-stored data.

How It Works:

The PWRview system aggregates solar production data from the inverter(s) via Modbus TCP/IP or similar protocol. This data is transmitted to the Generac cloud servers for processing and storage. The app retrieves this processed data from the cloud. Incorrect yearly production can result from data aggregation errors, cloud synchronization failures, or incorrect date settings within the PWRview gateway.

Preventative Care:

Regularly check for and install firmware updates for the PWRview gateway and app.
Periodically verify the date and timezone settings on the PWRview gateway.
Monitor the PWRview app for any unusual data fluctuations or errors.
Ensure a stable and reliable internet connection for the PWRview gateway.
