Troubleshoot a 'Grid Profile Not Supported' error on a Generic Hybrid Inverter in a residential solar + storage system. Solutions & safety tips.
Contact your local utility company. They can provide the required grid profile specifications.
Visit the inverter manufacturer's website or use the inverter's monitoring app. Firmware updates are usually available for download.
Contact your local utility company to report the issue. Do not attempt to adjust the grid voltage or frequency yourself.

Hybrid inverters are designed to synchronize with the local utility grid's voltage, frequency (60Hz in North America), and phase. The inverter utilizes a digital signal processor (DSP) to monitor the grid parameters and adjust its output to match. The 'Grid Profile Not Supported' error indicates a mismatch or incompatibility between the inverter's programmed grid profile and the actual grid parameters detected. This could be due to incorrect configuration, outdated firmware, or abnormal grid conditions.
The hybrid inverter displays a 'Grid Profile Not Supported' error, preventing grid synchronization and energy export. The system may be operating in off-grid mode, relying solely on battery power or solar energy, but cannot feed excess power back to the utility grid.
Many inverters have a 'Test Grid' function in the service menu that simulates grid conditions to verify synchronization. Access this hidden menu (refer to the service manual) and observe the inverter's response. If the test fails, it indicates an internal inverter issue rather than a grid problem.
