Community wind turbine · 50 kW class
The first model in the range that is a turbine rather than an appliance: a 16 m rotor, a 3.5 tonne nacelle, an IEC II design class and a crane on site for a week. It is also the smallest machine that a bank will usually finance as generation assets.
The GH-D50KW carries a 16 m rotor with 201 m² of swept area, a 3.5 t nacelle and a tower of 20, 24 or 30 m weighing six tonnes. Cut-in is 2.5 m/s, rated wind speed 11 m/s, survival 59.5 m/s, and the whole machine is designed to IEC II — the class that covers most inhabited coastal and inland sites outside typhoon zones. At a 6 m/s mean it produces around 125 MWh a year.
What separates it from the 30 kW frame is not just swept area. Three braking systems act independently — aerodynamic, mechanical and hydraulic — pitch is fixed, and the generator can be specified as permanent-magnet synchronous or asynchronous depending on whether you want low-speed efficiency or easy service from a local motor rewinder. That combination is what makes it bankable: an insurer, a lender and a grid operator can all find the documents they expect.

Price depends on tower height, controller and battery bank — ask for a quote with your site details.
Rated 11 m/s, cut-in 2.5 m/s, survival 59.5 m/s. IEC II design class, which covers most inland and coastal sites outside the typhoon belt.
Aerodynamic, mechanical and hydraulic braking, each able to stop the rotor alone. This is the configuration grid operators and insurers ask for at this scale.
No pitch motor, no pitch battery, no blade-bearing encoder. Output is managed by generator torque and furling rather than blade angle.
Tower mass 6 t. Erection with a 50 t crane in three to four days; foundation design supplied against your soil report and 50-year gust.
One machine supplies roughly 35 households at a 6 m/s site — the size that fits a village fund, a co-operative or a municipal budget.
Offsets the daytime load of a 40–60 kW plant and cuts peak demand charges without touching the grid connection capacity.
Displaces 30,000–40,000 litres of diesel a year on an island with a 60–100 kWh battery and 30 kW of PV.
