EEPROM Non-Essential Data Access Failure

Hva betyr EEPROM ?

A transition failure occurred during the reading or writing of non-essential data in the EEPROM of the Sunny Boy SB50US-80US-IUS094030. This issue does not impact the inverter's performance or its safe operation.

• Internal failure during EEPROM access for non-critical data.

1. 1

   Verify inverter operational status and review system event logs for any additional associated fault codes or warnings.

2. 2

   Check the installed firmware version against the latest available from SMA and plan an update if a newer version addresses known EEPROM stability issues.

3. 3

   Perform a controlled shutdown and restart of the inverter according to the SMA service manual procedures to clear any transient software states.

4. 4

   Inspect all external communication bus connections (e.g., Modbus, Ethernet) for proper seating and physical integrity, as non-essential data may pertain to communication parameters.
