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 are the wind resource requirements for installation?

Annual average wind speed should be more than 3m/s, with effective wind speed (3-20m/s) exceeding 3000 hours per year and power density over 100W/m2.

Q:How do I calculate the required wind turbine power for my home?

Calculate total daily energy consumption (Watt-hours) and ensure the turbine's output, considering battery efficiency (approx. 70%), meets or exceeds this demand to prevent battery damage.

Q:How to select the correct battery capacity?

Battery capacity should generally match the turbine power. For example, a 100W turbine needs a 120AH battery, while a 1000W turbine requires a 360AH battery.

Q:What is the rated power and voltage of the RX-3KL model?

The RX-3KL model has a rated power of 3100W and supports voltages of 220V, 240V, or 380V.

Q:What is the start-up wind speed for this turbine?

The start-up wind speed is 3m/s, with a rated wind speed of 10m/s and a maximum wind speed tolerance of 35m/s.
