EEPROM fault
Also displayed as F50 on some models.
Fault — the inverter cuts its output and the red LED stays solid until the fault is cleared.
The exact meaning depends on your model:

EEPROM fault
Cause: The EEPROM that stores the unit's settings and calibration data failed a read/write check. This is an internal memory fault.
Contact the repair center.

INV over Current of hardware — Inverter hardware over current fault.
Cause: The inverter stage's hardware overcurrent protection tripped — an instantaneous trip, independent of the firmware, that reacts to fast surges or a short on the output side.

EEPROM failure
Cause: A read/write error occurred in the EEPROM that stores the inverter's settings and calibration, so the control board cannot reliably save or recall its configuration.
Restart the unit, if the error persists, contact the repair center.

Inverter current DC component fault — Inverter current DC component is too high, shutdown and restart.
Cause: A DC component beyond the permitted limit was detected in the inverter's output current — the output waveform has developed an asymmetry the unit is not allowed to feed to loads or the grid.
