What does Fan alarm mean?

The cooling fan is either at a standstill despite being required to operate, or its speed has significantly decelerated, indicating a malfunction. The cooling fan is essential for dissipating heat from the inverter. Without adequate cooling, the inverter will overheat and trip, potentially leading to irreversible component damage.
