Alarm 2110Power Control Abnormal at Grid Connection Point

Name in the manufacturer's documentation (fault list): Power Control Abnormal at Grid Connection Point[1]

In plain words (editorial)

Power control at the grid connection point is abnormal – meter communication failed or the current at the grid connection point exceeded the threshold, so the inverter stopped grid connection. The manual notes that at most 3 manual startup commands can be sent within 30 days.

When to call a service technician: Have your installer check the meter cable; if the fault persists, contact Huawei technical support.
