GHREPOWER Ltd.

“GHREPOWER has been the perfect choice for us at our farms. Their wind turbines are far superior

to any other turbine we looked at...; Plus the support we have received during the installation and

even after we have been up and fully operational has been very impressive ...”

M. Roenfanz, Ventura, IA, USA

“GHREPOWER has commissioned two 50kW turbines in a public park environment with many

challenges. The commitment of the team to deliver this project in a timely

professional manner was exemplary. The turbines are fully commissioned, helping reduce our

carbon footprint.”

“In our opinion, the Eastwind turbines* have proven to be the most reliable in their class, both from a

reliability and performance standpoint...”

Private Energy Systems, Inc., USA

*GHREPOWER retails under ‘Eastwind’ in the USA.

“The quality of the components and the technology, both in design and construction, place

GHREPOWER products on the highest range in the sector…”

GHREPOWERPOWERING YOUR FUTURE

www.ghrepower.co.uk01792 846953

GHREPOWER is one of the world’s leading system providers of small and medium wind power

products. The GHREPOWER headquarters and factory are based in Shanghai and the products

are exported worldwide. GHREPOWER, UK, based in South Wales, opened for business in 2011,

to supply the GHREPOWER 50kW and 100kW wind turbines to the UK market.

Who is GHREPOWER?》

The Team

Technology

Certification

The establishment of GHREPOWER has its origin in the research and application mandate at the

China Wind Research Institute dating back to 1978. Today, GHREPOWER employs more than

200 people worldwide, and focuses its design and development purely on the small and medium

sized wind turbine systems. GHREPOWER has a dedicated workforce and experienced

Research and Development Team of more than 30 engineers from a wide variety of backgrounds,

including civil, mechanical, aerodynamics, electrical, electronics, computer science and

software.

GHREPOWER holds over 30 technical patents in the design of its Gearless-Direct-Drive,

Permanent Magnetic Generator, Controller and Inverter; Ideal for farmers, businesses and

communities. All components of the system come with a 5 year manufacturer’s warranty and a

five-year maintenance contract is also available.

GHREPOWER is the first and only small wind turbine manufacturer in China to proceed with

independent testing outside of China. The GHREPOWER 50kW turbine is currently undergoing

MCS testing at the TUV site in Scotland, with testing to be completed in 2012.

Worldwide Installations Why GHREPOWER?

Direct Drive PM Technology

Intelligent Multi-Level Protection

Low Noise Design

MCS Wind Turbine Testing By TUV NEL

Applications

Examples

Our gearless direct drive Permanent Magnet technology eliminates the need for a

gearbox in induction type generator. This results in improved generating

efficiency and system reliability.

The smart pitch control brake, mechanical brake, electromagnetic brake, dump

load and active yaw system are intelligently controlled and adjusted under

extreme weather conditions to ensure the highest levels of safety and protection.

With an optimised low speed Permanent Magnet Generator and favourable

aerodynamic characteristics of the blades, the noise level is reduced to a

minimum.

The GHREPOWER 50kW wind turbine is in the process of MCS testing based on

the IEC and BWEA standard in Scotland. Certification is expected imminently.

The GHREPOWER 50kW is suitable for domestic, commercial and community

applications.

Applications

Examples

The first 100kW wind turbine with gearless, active pitch control and

permanent magnet generator design in the world.

The smart pitch control brake, mechanical brake, electromagnetic brake,

dump load and active yaw system are intelligently controlled and adjusted

under extreme weather conditions to ensure the highest levels of safety and

protection.

GHREPOWER’s full power inverter converts and transfers unsteady wind

energy to a steady AC power of constant frequency and voltage to the grid. It

isolates the wind turbine from the grid to ensure the wind turbine’s safety and

minimise disturbance to the grid.

The GHREPOWER 100kW is suitable for domestic, commercial and

community applications.

–Korean National Smart Grid project in South Korea;

Commercial investment project in Italy;

–An American innovative project in Massachusetts;

Active pitch control technology allows the turbine to automatically adjust its

pitch angle during periods of strong wind and capture more wind energy

during periods of low wind. It also ensures a steady power output, increasing

efficiency.

GHREPOWER have a national technical patent on this design.
