Power derating caused by excessively high temperatures

What does 517 mean?

When the inverter's internal temperature becomes excessively high, it initiates power derating to protect components, displaying a warning message. The system automatically reduces output power until temperatures return to a safe range.

• Excessively high ambient temperatures around the inverter
• Obstructed cooling air openings preventing adequate airflow
• Accumulation of dirt or debris on the heat sink reducing cooling efficiency

Click steps to track your progress.

1. 1

   Purge any obstructions from the cooling air openings of the inverter

2. 2

   Clean the heat sink to ensure proper heat dissipation
