How do I fix a faulty Huawei inverter?
Turn off the AC output switch and DC input switch. Then turn on the AC output switch and DC input switch after 5 minutes. If the fault persists, contact Huawei technical support. The internal power chip of the sampling control board is faulty. The detection circuit becomes faulty. When the alarm is generated, the inverter shuts down automatically.
Why is my Huawei inverter NOT working?
The inverter automatically recovers after the fault is rectified. 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.
What happens if a Huawei inverter is unrecoverable?
An unrecoverable fault occurs on a circuit inside the inverter. The inverter detects its external working conditions in real time. After the fault is rectified, the inverter automatically recovers. If the alarm occurs repeatedly, contact Huawei technical support. Turn off the AC output switch and DC input switch.
What happens if a Huawei inverter alarm is generated?
When the alarm is generated, the inverter shuts down automatically. When the fault is rectified, the inverter starts automatically. If the alarm occurs repeatedly, contact Huawei technical support. During inverter software upgrade, the version of the software loaded is incorrect.
What should I do if my Huawei power grid fails?
If the fault persists, contact your dealer or Huawei technical support. The impedance of the output phase wire to PE is low or the output phase wire is short-circuited to PE. Check the impedance of the output phase wire to PE, locate the position with lower impedance, and rectify the fault. The power grid experiences an outage.

The Wi-Fi chip of the mobile phone is incompatible with the inverter Wi-Fi network. Cellular Data. If the connection to the inverter Wi-Fi network still fails, restart the mobile phone. Choose Settings > Wi-Fi on the phone. Select the corresponding inverter Wi-Fi network, and manually configure the IP Address, Subnet Mask, Router, and DNS servers.
Featured Solar Products
High - Efficiency Photovoltaic Panels
Our photovoltaic panels are at the forefront of solar technology. With advanced cell designs and high - quality materials, they offer exceptional energy conversion rates, allowing you to maximize your solar energy harvest. Whether installed on a residential rooftop or a large - scale solar farm, these panels are built to last, withstanding harsh weather conditions and providing reliable performance for decades.
Advanced Monocrystalline Solar Panels
These advanced monocrystalline solar panels are crafted from single-crystal silicon, which endows them with outstanding electrical properties. They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
