6 FAQs about [Photovoltaic inverter alarm self-recovery]

What happens if a PV inverter fails?

The inverter monitors its external operating conditions in real time and automatically recovers after the fault is rectified. If the alarm persists and affects the energy yield of the PV plant, contact your dealer or Huawei technical support. The insulation impedance of the input side to PE decreases when the inverter is operating.

How do I know if my inverter has an Isolation Fault?

You can identify an isolation fault using either SetAPP or the inverter LCD display. An isolation fault may disappear and recur after a short period (especially if it is caused by morning moisture), therefore it is recommended to troubleshoot the fault as soon as it occurs before it disappears.

What should I do if my inverter has a power grid alarm?

If the alarm occurs occasionally, the power grid may be abnormal temporarily. The inverter automatically recovers after detecting that the power grid becomes normal. If the alarm persists, check whether the power grid frequency is within the acceptable range. If not, contact the local power operator.

What is a PV inverter?

PV inverter is considered as the brain of the PV system. Studies have demonstrated that it is the most vulnerable component . Inverter failures are classified into different categories: Manufacturing and design problems: PV inverter performance depends on operating conditions and the system lightening.

Why is my inverter alarm not working?

If the alarm occurs accidentally, the external power cable may be abnormal temporarily. The inverter automatically recovers after the fault is rectified. If the alarm persists or lasts a long time, check whether the impedance between the PV string and ground is too low. The neutral wire or PE cable of the inverter is not connected.

What should I do if my inverter fails?

If the fault persists, contact your dealer or technical support. The DC component of the inverter output current exceeds the upper threshold. The inverter monitors its external operating conditions in real time and automatically recovers after the fault is rectified.
