Was bedeutet 2 ?

An EEROM (Electrically Erasable Read-Only Memory) fault indicates an issue with the non-volatile memory used for storing configuration or operational data. This can lead to incorrect settings or failure to store critical operational parameters, potentially affecting system stability.

• Corruption of EEROM data
• Failure of the EEROM chip

1. 1

   Measure DC input voltage and AC output voltage stability, comparing readings to specified operational ranges.

2. 2

   Verify all configurable operational parameters and settings through the inverter's user interface against the system's design specifications.

3. 3

   Check the installed firmware version and compare it against the latest recommended version from Fronius, noting any available update recommendations.

4. 4

   Attempt a controlled reset of user-configurable parameters to factory defaults, followed by careful re-entry of essential site-specific settings.
