Grid Undervoltage

What does 2033 mean?

The power grid voltage has dropped below the lower threshold, or the undervoltage duration has exceeded the value specified by LVRT (Low Voltage Ride Through). This condition indicates an unstable or insufficient grid supply.

• The power grid voltage is below the lower threshold.
• The undervoltage duration exceeds the value specified by LVRT.
• The power grid may be abnormal temporarily.
• The grid undervoltage protection threshold is set incorrectly.
• The connection between the AC switch and the output power cable is faulty.

Click steps to track your progress.

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 undervoltage protection threshold with the consent of the local power operator.

3. 3

   Check the connection between the AC switch and the output power cable.
