Output overcurrent

What does 2039 mean?

The SUN2000's transient output current exceeds its upper threshold, triggering protection due to a dramatic drop in power grid voltage or a short-circuited power grid. This indicates an external electrical fault affecting the inverter's output.

• The power grid voltage drops dramatically.
• The power grid is short-circuited.

Click steps to track your progress.

1. 1

   Observe if the SUN2000 automatically recovers after the fault is rectified, as it monitors external operating conditions in real time.

2. 2

   If the alarm persists and affects energy yield, check whether the output is short-circuited.
