Output Overcurrent

What does 2039 mean?

The SUN2000's transient output current exceeds its upper threshold, triggering protection, typically due to a dramatic drop in grid voltage or a short circuit in the power grid. This protects the inverter from excessive current.

• The power grid voltage drops dramatically.
• The power grid is short-circuited.
• The SUN2000 transient output current exceeds the upper threshold.
