Vertical axis wind turbine · 5 kW class
A rotor that does not care where the wind comes from. Five aluminium blades on a 3 m H-rotor, a 2 m/s cut-in, and 45 dB at any wind speed — the machine for sites where the direction changes every few seconds and a tail vane would spend its life chasing it.
The GH-H5000 is an H-type Darrieus rotor: five straight aluminium-alloy blades, 5 m tall, on a 3 m diameter, with two layers of inner blades to help it start in low wind. The generator sits at the base of a vertical shaft, so there is no yaw bearing, no tail vane and no slip ring. Cut-in is 2.0–2.5 m/s depending on the generator version, rated wind speed 11–12 m/s, survival 45 m/s.
Because the rotor presents the same profile to wind from any direction, output does not collapse when the wind swings 90° — the failure mode that costs a horizontal axis machine most of an afternoon on a coastal site or a ridge saddle. The trade-off is real and worth stating: at the same swept area an H-rotor extracts 20–30 % less energy than a three-blade horizontal axis machine. You buy it for turbulence, height limits and noise limits, not for maximum kWh per square metre.

Wind from any direction produces torque. There is no mechanism to wear out pointing the rotor into the wind, and nothing to fold in a gust.
The tip speed is low, so the aerodynamic noise that makes a HAWT audible at 8 m/s never develops. This is the model that gets approved next to a dwelling.
The inner blade layers add starting torque, so the rotor begins turning in wind that a pure Darrieus would need 4 m/s to self-start.
Aluminium blades, sealed generator and a temperature range that covers Canadian prairies, Nordic coasts and Gulf heat with the same hardware.
Rooftop frames, car park canopies and campus edges where a three-blade rotor would fail the noise or visual test.
Sea breeze by day, land breeze by night — 180° swings that leave a tail-vane machine hunting for the wind.
A 5 kW H-rotor and a 48 V battery bank keep a radio site alive where the wind is good but gusty and dirty.
