Transient AC Overvoltage

What does 2072 mean?

The inverter detects that the phase voltage exceeds the transient AC overvoltage protection threshold. This indicates a sudden, temporary spike in the AC grid voltage.

• The inverter detects that the phase voltage exceeds the transient AC overvoltage protection threshold.
• The grid connection voltage exceeds the upper threshold.
• The peak power grid voltage exceeds the upper threshold.

Click steps to track your progress.

1. 1

   Check whether the grid connection voltage exceeds the upper threshold.

2. 2

   If you have confirmed that the grid-tied voltage exceeds the upper threshold and have obtained the consent of the local power operator, modify the overvoltage protection threshold through the mobile phone app, SmartLogger, or NMS.

3. 3

   Check whether the peak power grid voltage exceeds the upper threshold.
