AI-Powered supplier vetting

SummaryQingdao Greef New Energy Equipment Co., Ltd. is identified as both a trading company and manufacturer/factory in China, offering wind turbines, permanent magnet generators, hybrid systems, and related equipment. Its stated capabilities include generator coverage from 500W to 5MW, two production lines, annual output of 1,000 wind turbine/permanent magnet generator sets, and 6–10 R&D engineers and quality-control staff. The company reports QHSE, ISO 9001, and HSE management certifications, CE-certified exports, warranty periods of 3–5 years, and after-sales service as part of its end-to-end offering. Evidence also supports customization through design, prototyping, production, and quality-control services. However, the provided information does not sufficiently establish financial credibility or a broad customer track record; only one buyer and one trade transaction are listed.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory. Its stated product portfolio includes wind turbine systems, permanent magnet generators, controllers, inverters, solar systems, and batteries, supporting a combined manufacturing and trading role.

CertificationsThe supplier states that its management systems include QHSE, ISO 9001, and HSE. It also states that products exported to Europe, South America, and North America carry CE certification, indicating documented management-system and product-certification claims.

After-Sales capabilityThe company describes end-to-end services including after-sales service and states that exported products have 3–5 year warranty periods. It also claims rapid response and guaranteed quality and on-time delivery through Alibaba Trade Assurance, providing explicit support for post-sale capability.

R&D capabilityThe supplier states that its permanent magnet generators range from 500W to 5MW and offers multiple renewable-energy technologies, including vertical- and horizontal-axis wind turbines, hybrid systems, and disc coreless generators. Its stated engineering and renewable-energy innovation activities support innovation capability, although no independently verified R&D results are provided.

Production capacityThe supplier reports two production lines and annual output of 1,000 wind turbine/permanent magnet generator sets. It also states generator coverage from 500W to 5MW and has 6–10 quality-control staff, providing explicit evidence of established production capacity.

This directly supports customization capability across product-development and delivery stages.

Product Q&A

Q:Can the solar power system be customized?

Yes, the system can be customized according to your specific requirements, and the price varies based on the equipment selected.

Q:What power options are available?

The system is available in 5KW and 10KW load power configurations.

Q:How does the system work in off-grid mode?

In off-grid mode, solar electricity is stored in batteries to ensure power supply, and users can add diesel or grid power to adjust energy source priority.

Q:What happens in grid-connected mode?

In grid-connected mode, the inverter feeds excess power back into the grid or offsets it for self-consumption without requiring battery storage.

Q:What mounting structures are supported?

The system supports ground or roof mounting structures, with customized options available.
