Vertical axis wind turbine · 50 kW class
Community-scale H-rotor. 132 m² of swept area, a generator at the base of the mast, and a rotor that keeps producing through the 90° wind shifts that make a tail-vane machine hunt all afternoon.
The GH-H50K turns an 11 m diameter, 12 m tall rotor — 132 m² of swept area — on a 15, 18 or 24 m free-standing tower. Five aluminium blades with three inner blade layers, a disc-type coreless PMG at ground level, electromagnetic brake with optional mechanical lock. Cut-in 2.2 m/s, rated 11 m/s, survival 45 m/s, 45 dB(A) at 10 m.
On a 5.5 m/s site it produces about 85,000 kWh a year. The commercial case is almost always diesel displacement: a 50 kW genset burning 12–15 litres an hour costs far more per kWh than this machine, and on an island or a mine the fuel logistics cost more again. The H-rotor layout means the generator, controller and brake are at the base — no 24 m nacelle work, no crane for routine service.

Price depends on tower height, controller and battery bank — ask for a quote with your site details.
Five blades in three sections each, assembled on site. Blade height and diameter both scale, so the rotor keeps a low aspect ratio and stays structurally stiff.
All service items within 2 m of the ground. For an island or a mine, that is the difference between a local technician and a flying engineer.
Low tip speed and no gearbox. The machine can sit 60 m from a dwelling where a 50 kW HAWT would need 150 m.
Blades and tower designed for a 45 m/s gust with the rotor locked. Not typhoon-rated: for 59.5 m/s exposure choose the GH-D50KW.
Two units, 60 kW of PV and a 200 kWh battery replace a 100 kVA diesel set on a small island grid, with the diesel kept for calm weeks.
Displaces 40–60 % of genset fuel on sites where the wind is gusty and the load is flat, without a crane on site for service.
The controller accepts a diesel-off signal and curtails output on low load, so the retrofit does not need a new grid-forming inverter.
