Active power limited derating

What does 8003 mean?

The inverter has reduced its power output for more than ten minutes due to excessive internal temperature. This derating is a protective measure to prevent damage from overheating, impacting power generation capacity.

• Accumulation of dirt or debris on the cooling fins or air ducts, impeding heat dissipation.
• Insufficient ventilation around the inverter enclosure.
• Ambient temperature exceeding +40°C.
• Inverter exposed to direct solar irradiation, increasing internal temperature.

Click steps to track your progress.

1. 1

   Clean the cooling fins on the rear of the enclosure and the air ducts on the top using a soft brush.

2. 2

   Verify the inverter's installation location ensures sufficient ventilation.

3. 3

   Measure and confirm the ambient temperature does not exceed +40°C.

4. 4

   Ensure the inverter is not exposed to direct solar irradiation.
