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 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.
How do I change the grid connection status of the inverter?
The grid connection status of the inverter is switched by using the Backup Box. The critical load power does not exceed the max off-grid output power of the Inverter. You can add inverters and batteries to increase capacity. A maximum of three inverters can be cascaded.
What happens if a power inverter is set to 100?
If this parameter is set to 100, the inverter outputs based on the maximum output power. Night-time reactive power output In some specific application scenarios, a power grid company requires that the inverter can perform reactive power compensation at night to ensure that the power factor of the local power grid meets requirements.
How does a power grid frequency adjustment work?
Adjusts the active output baseline of the inverter. The standards of certain countries and regions require that if the power grid frequency fluctuates around the rated value, the inverter needs to fine-tune the active power output based on Frequency-based adjustment ratio to help stabilize the power grid frequency.
How many solar inverters can be connected to ESS?
The grid-tied and off-grid ESS supports a maximum of three SUN2000- (2KTL-6KTL)-L1 inverters (with batteries) cascaded. In this scenario, the inverters can be connected to the grid only at the same phase and controlled only by a single-phase power meter. Grid connection at different phases or using a three-phase power meter is not supported.
Featured Solar Products
High - Efficiency Photovoltaic Panels
Our photovoltaic panels are at the forefront of solar technology.

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.
