Memory error detected

What does 451 mean?

This code indicates that a memory error has been detected within the inverter's internal memory. This can affect system stability and data integrity, but the inverter will automatically attempt to reconnect and resume feeding if possible.

• Corrupted data in internal RAM or persistent storage (EEPROM/Flash).
• Faulty memory chip or associated circuitry.
• Transient power fluctuations causing memory write errors.

Click steps to track your progress.

1. 1

   If the status code is displayed continuously, notify a Fronius-trained service engineer for internal diagnosis.

2. 2

   Perform an AC reset by cycling the automatic circuit breaker to clear transient memory states.

3. 3

   Check for stable internal power supplies to the memory modules.
