Fixed voltage mode has been selected instead of MPP voltage mode, and the fixed voltage has been set to too low or too high a value.

Was bedeutet 412 ?

This code indicates a configuration error where 'Fixed voltage mode' has been selected instead of 'MPP voltage mode,' and the configured fixed voltage value is either too low or too high for proper operation. This prevents the inverter from efficiently extracting power from the PV array.

• Incorrect inverter configuration setting for DC input voltage mode (Fixed vs. MPP).
• Fixed voltage parameter set outside the permissible or optimal range for the connected PV array.
• Human error during inverter setup or commissioning.

1. 1

   If this status code keeps recurring, contact your system engineer for diagnosis.

2. 2

   Access the inverter's settings menu and change the DC input voltage mode to 'MPP voltage mode' if applicable.

3. 3

   If fixed voltage mode is required, verify the set voltage value is within the optimal operating range of the PV array and adjust it.
