Click steps to track your progress.

1. 1

   Power down the Fronius Primo GEN24 208-240 inverter using both AC and DC disconnects, then allow it to cool down completely.

2. 2

   Carefully inspect the fan vents and fan blades for any obstructions (dust, debris, insects) and clean them if necessary.

3. 3

   Check if the fan spins freely by gently trying to move it (with power off and safely discharged).

4. 4

   Ensure the inverter's installation location provides adequate ventilation and is not exposed to direct sunlight or confined spaces that could impede airflow.

5. 5

   If the fan remains faulty after cleaning and inspection, contact Fronius service for potential fan replacement, as this indicates an internal component failure.
