Over Temperature
Inverter internal temperature too high
Common causes
Inadequate ventilation
High ambient temperature
Dirty heat sink fins
What to check
STEP 1
Verify clearances: min 200mm top, 150mm left/right, 100mm bottom
STEP 2
Clean heat sink fins — remove dust and debris
Escalate if
Temperature remains high after clearing obstructions and improving airflow
