Grid Code Violation

What does 801 mean?

This status code indicates that the Fronius Primo GEN24 208-240 inverter has detected a violation of the local grid code, leading to a shutdown. This occurs when grid parameters (such as voltage or frequency) fall outside the permissible limits defined by the selected grid code, or if an incorrect grid code has been configured.

• AC grid parameters (voltage, frequency) are unstable or outside the limits specified by the selected grid code.
• Incorrect country setup or grid code selection in the inverter's parameters, not matching local utility requirements.

Click steps to track your progress.

1. 1

   Measure the AC grid parameters (voltage and frequency) at the inverter's connection point to confirm stability and adherence to grid code limits.

2. 2

   Verify the selected country setup and grid code in the inverter's parameters to ensure it correctly matches the local utility requirements.

3. 3

   De-energize the inverter (switch off AC and DC disconnects), wait for 5 minutes, then re-energize. If grid conditions are stable and settings are correct, but the message persists, the inverter may require service.
