1. 1

   Initiate a full power cycle of the Fronius Primo GEN24 208-240 inverter by carefully disconnecting both AC and DC power, waiting, and then reapplying power.

2. 2

   Monitor the inverter's diagnostic data (if accessible) to identify which sensor might be reporting abnormal values.

3. 3

   Check for any environmental factors (e.g., extreme temperature fluctuations, vibrations) that could affect sensor readings.

4. 4

   Review the inverter's event log for any prior or concurrent fault codes that might offer more clues about the sensor failure.

5. 5

   If the error persists, it suggests a hardware defect with an internal sensor or its associated circuitry; contact Fronius service for specialized diagnostics.
