If a product problem occurs, what is the after-sales process?

Generally, you should first contact our retailer or manufacturer's after-sales customer service and provide a detailed description of the problem, including the product model, purchase date, and the problem. After-sales personnel will make a preliminary assessment based on your description and provide a solution. If the problem is a hardware issue, the product may need to be returned to the manufacturer for inspection and repair. We will repair the product and return it to you within the specifi

AI-Powered supplier vetting

SummaryMaoxin New Energy is an inverter-power and emerging-energy-technology supplier with stated OEM/ODM experience and broad product and technical-service activities. It holds ISO 9001 certification, operates one production line, and reports one quality-control inspection staff member, six test-equipment units, and one R&D engineer. The supplier offers flexible customization and provides technical support for production and after-sales service. However, it has only one year of export experience, no stated SDK availability, no valid manufacturing-capacity contract with related subcontractors, and no in-stock, overseas warehouse, or overseas showroom capability. It reports no cooperation with Fortune 500 companies. Financial information is present only as year labels, which is insufficient to assess credibility.

Supplier typeThe supplier is a manufacturer and technical-service provider focused on emerging energy technologies, power electronics, batteries, distribution switch-control equipment, and related components. Its stated ambition and industry positioning center on inverter power, while the available information does not establish whether it is a trading company or manufacturer-only entity.

CertificationsThe supplier reports holding ISO 9001 certification. This explicitly supports the presence of a recognized quality-management-system certification, although no certificate scope, issuing body, or validity details are provided.

After-Sales capabilityThe R&D engineer is responsible for technical support for production and after-sales service, and technical services are included in the business scope. However, the supplier reports no in-stock service capacity and no overseas warehouse or showroom, so the evidence supports technical after-sales assistance but not comprehensive local or inventory-based service coverage.

R&D capabilityThe supplier states that innovation and R&D are central to its development, conducts emerging-energy-technology research, and has one R&D engineer responsible for customer-request confirmation, product design, and technical support. It plans further R&D investment, but reports no available SDK, so its innovation capability is supported at a basic product-development level rather than a demonstrated software-development platform level.

Production capacityThe supplier lists welding, cutting, bending, drilling, and soldering equipment, operates one production line, and has written warehouse-control procedures with retained records. Production quality resources are limited to one inspection staff member and six test-equipment units, while no valid manufacturing-capacity contract with related subcontractors and no in-stock capacity are reported; overall production capability is evidenced but limited in scale and support flexibility.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D engineer is responsible for confirming customer requirements and designing new products, directly supporting the stated customization services.

Client casesThe supplier states that it provides long-term OEM/ODM services to numerous prominent domestic and international new-energy enterprises and offers OEM services for well-known brands. However, it reports no cooperation with Fortune 500 companies and provides no named customer cases, so the breadth of experience is asserted but independently specific case evidence is limited.

Product Q&A

Q:What is the efficiency of the power inverter?

Our high-quality power inverters are highly efficient. Pure sine wave inverters utilize high-efficiency transformer isolation, resulting in high overall inverter efficiency and low no-load losses. Efficiency can reach over 90%, with some even reaching around 95%.

Q:What types of inverter output waveforms are available? What are the differences?

There are two main types: pure sine wave and modified sine wave. The waveform output by a pure sine wave inverter is essentially the same as the mains sine wave, offering greater load efficiency and capacity. It can operate inductive loads and any other common AC loads, including refrigerators, televisions, and radios, without interference or noise, and without affecting the performance and lifespan of the load equipment. The waveform output by a modified sine wave inverter is closer to a sine w

Q:Why is the inverter having no output?

This could be due to a problem with the input power connection, such as a loose or poorly connected input power cord, or an internal short circuit in the power cord. It could also be caused by a blown fuse. When an abnormal condition such as a short circuit or overload occurs within the inverter, the fuse will quickly blow, shutting off the circuit. Additionally, a switch failure or internal circuit malfunction can also cause the inverter to lose output.

Q:What should I do if the output voltage is unstable?

If the cause is large input voltage fluctuations, check the input power supply. If the battery is low, recharge or replace it. If using a rectified DC power supply from AC mains, install a voltage stabilizer on the input side. If the load fluctuates frequently and exceeds the rated output power, avoid running too many high-power devices simultaneously and ensure that the total power of the loads connected to the inverter does not exceed its rated output power. If the inverter's internal voltage

Q:Can a power inverter be customized according to my needs?

Most Chinese manufacturers offer customization services. You can specify your specific requirements, such as input and output voltage, power, waveform type, size, and special features, and we will design and produce according to your requirements.
