6 FAQs about [Huawei photovoltaic inverter fault maintenance]
What should I do if my Huawei inverter is not working?
If the ventilation and ambient temperature both meet requirements, contact your dealer or Huawei technical support. An unrecoverable fault has occurred on a circuit inside the inverter. Turn off the AC output switch and DC input switch, and then turn them on after 5 minutes. If the fault persists, contact your dealer or Huawei technical support.
Does Huawei solar inverter detect arc faults?
Function If PV modules or cables are incorrectly connected or damaged, electric arcs may be generated, which may cause fire. Huawei solar inverters provide arc detection meets the requirement of UL 1699B-2018, ensuring the user safety and property. This function is enabled by default. The solar inverter automatically detects arc faults.
Why is my Huawei inverter alarm not working?
If the alarm occurs frequently, contact your dealer or Huawei technical support. The input-to-ground insulation impedance has decreased during the inverter operation. If the alarm occurs accidentally, the external power cable may be abnormal temporarily. The inverter automatically recovers after the fault is rectified.
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.
Can a Huawei inverter be installed outside in Salt areas?
Before installing the inverter outdoors in salt areas, consult Huawei. A salt area refers to the region within 500 meters from the coast or prone to sea breeze. The regions prone to sea breeze vary with weather conditions (such as typhoons and monsoons) or terrains (such as dams and hills).
How long does it take a Huawei inverter to discharge?
Issue 02 (2022-06-30) Copyright © Huawei Technologies Co., Ltd. It takes 15 minutes for the inverter to discharge to the safe voltage. Refer to documentation Reminds operators to refer to the documents shipped with the inverter.
