How to solve Abnormal Grid Voltage alarm

During the inspection of a 20 MW PV plant, an inverter was found to report an alarm indicating that the power grid voltage was abnormal and no power was generated. Log

What should I do if my PV inverter fails?

The inverter automatically recovers after the fault is rectified. If the alarm occurs frequently and affects the power production of the PV plant, check whether the output is short-circuited. If the fault persists, contact your dealer or Huawei technical support. The DC component in the grid current exceeds the upper threshold.

How do I know if my inverter has a power grid problem?

The inverter automatically recovers after detecting that the power grid becomes normal. If the alarm occurs frequently, check whether the grid frequency is within the acceptable range. If no, contact the local power operator. The grid voltage drops dramatically or the power grid is short-circuited.

What happens if an inverter is undervoltage?

For undervoltage errors, an inverter repairer will need to check the condition of the battery and replace it if necessary. If the battery is in good condition, they check the panel’s connections to ensure that they are secure and not damaged.

What causes a DC inverter to overvoltage?

This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. Check supply voltage for constant or transient high voltage. Increase deceleration time.

What causes undervoltage?

Undervoltage This is caused by low intermediate circuit DC voltage. This can be caused by a missing supply voltage phase from a blown fuse or faulty isolator or contactor or internal rectifier bridge fault or simply low mains voltage. POSSIBLE FIXES: Check mains supply and fuses.

Why does my sun2000 inverter alarm disappear?

After the PV array is correctly configured, the inverter alarm disappears. The PV string power cable arcs or is in poor contact. Check that the PV string power cable does not arc and is in good contact. The PV string polarity is reversed. Check whether the PV string is reversely connected to the SUN2000.
