AI-Powered supplier vetting

SummaryNantong R&X Energy Technology Co., Ltd. is identified as a limited company and trade company in Nantong, China, with four employees and a valid import/export license. It reports OEM and ODM services, extensive customization options, export experience of 11 years, and export sales representing 51%–70% of total sales. Reported annual capacity includes 100,000 wind turbines and 50,000 permanent magnet generators. However, it has no available SDK, no new products in the past year, and lacks overseas warehouses, showrooms, agents or branches, and offline trade-show participation. Service procedures are incomplete in documentation: some procedures exist without records, while corrective and preventive action procedures are absent. Financial information only identifies years and does not provide sufficient evidence of financial strength. No customer cases or brand references are provided. The audit information lists BV as the auditing organization, but the stated audit result is 0 and no certification details...

Supplier typeThe supplier is described as a limited company and trade company located in Nantong, with four employees and no associated company group. It holds a valid import/export license, while the primary product is identified as wind turbines.

After-Sales capabilityThe supplier has written procedures for service assessment and complaint handling, but no records; it has no written corrective and preventive action procedures or records. It reports one-month lead times and five qualified service-capability suppliers, but has no overseas warehouses, showrooms, agents or branches, and offers overseas services in zero countries.

R&D capabilityThe supplier provides ODM services and multiple design-service options, but explicitly has no available SDK and no new products reported during the past year. These stated limitations prevent a positive assessment of current innovation capability.

Production capacityReported annual productivity is 100,000 wind turbine sets and 50,000 permanent magnet generator pieces. These figures provide explicit evidence of stated production capacity for the listed products.

Customization capabilityThe supplier reports capabilities ranging from minor and flexible customization to customization from samples, designs, and full customization. The same broad range is also stated under R&D design services, supporting strong customization coverage.

Product Q&A

Q:What kind of region can be installed wind turbine?

Small wind turbines should be applied in regions with sufficient wind resources. The annual average wind speed should be more than 3m/s, with effective wind speed (3-20m/s) accumulating more than 3000 hours per year. The density of 3-20m/s effectively average wind power should be more than 100W/m2. It is important to choose a rated design speed wind turbine that conforms to local design speed to make use of wind resources and economic aspects.

Q:How to calculate the actual need power in my home to configure the appropriate power of wind turbines?

Battery stores power from the wind turbine and discharges to home appliances. The actual need power is the amount discharged to the load and charged timely by the wind turbine. For example, if a 100W turbine works for 4 hours, the battery charges 400WH. With only about 70% dischargeable, the usable power is 280WH. Calculate total daily consumption of appliances (e.g., bulbs, TV, radio) to determine if the turbine capacity is sufficient. If wind conditions are poor, reduce electrical application

Q:How to select the correct battery capacity to get power from wind turbine generator?

Generally, the battery capacity should be equal or smaller than the power from the wind turbine generator. Examples include: 100W turbine matches 120AH battery; 200W turbine matches 120-180AH battery; 300W turbine matches 240AH battery; 750W turbine matches 240AH battery; 1000W turbine matches 360AH battery.

Q:What is the warranty period for this wind turbine?

We provide a 5-year warranty for this wind turbine generator.

Q:What certifications does this wind turbine have?

This wind turbine is certified with CE, ISO, RoHS, and Ukca standards.
