Grid Overvoltage

Was bedeutet 2034 ?

The power grid voltage has exceeded the upper threshold, or the overvoltage duration has exceeded the value specified by HVRT (High Voltage Ride Through). This indicates an unstable or excessively high grid supply.

• The power grid voltage is beyond the upper threshold.
• The overvoltage duration exceeds the value specified by HVRT.
• The power grid may be abnormal temporarily.
• The grid overvoltage protection threshold is set incorrectly.
• The peak voltage of the power grid is too high.

1. 1

   Check whether the grid voltage is within the acceptable range.

2. 2

   Log in to the mobile phone app, SmartLogger, or NMS to modify the grid overvoltage protection threshold with the consent of the local power operator.

3. 3

   Check whether the peak voltage of the power grid is too high.
