Reduced Power Output — Inverter is Overheating

What does Reduced Power Output mean?

The SMA SUNNY BOY SB30-50-1AV-40 Inverter is operating at a reduced power level because its internal temperature is too high. This is a protective measure to prevent damage to the unit. Power output will increase once the inverter cools down.

• Inverter is exposed to direct sunlight.
• Ambient air temperature around the inverter is too high (above +40°C).
• Insufficient ventilation or blocked airflow around the inverter.
• Inverter is mounted in an enclosed space without adequate cooling.

Click steps to track your progress.

1. 1

   Ensure the inverter is shaded from direct sunlight; consider adding shading if needed.

2. 2

   Verify that the ambient temperature around the inverter's location is within the specified operating range (-25°C to +40°C).

3. 3

   Check for any obstructions around the inverter that might block airflow and ensure there is proper ventilation.

4. 4

   If the inverter consistently overheats, consider relocating it to a cooler, well-ventilated area.

5. 5

   If the issue persists despite these steps, contact a qualified installer or SMA Support for further assistance.
