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.
Click steps to track your progress.
Measure DC input voltage and AC output voltage stability, comparing readings to specified operational ranges.
Verify all configurable operational parameters and settings through the inverter's user interface against the system's design specifications.
Check the installed firmware version and compare it against the latest recommended version from Fronius, noting any available update recommendations.
Attempt a controlled reset of user-configurable parameters to factory defaults, followed by careful re-entry of essential site-specific settings.
