Cooling Fan Alarm

What does Fan alarm mean?

The cooling fan is either at a standstill despite being required to operate, or its speed has decelerated significantly. This indicates a potential failure of the cooling fan, which is critical for dissipating heat from the inverter's internal components. Continued operation without proper cooling will lead to overheating and subsequent damage to the inverter.
