Vertical axis wind turbine · 10 kW class
The largest H-rotor we build, and the one that ends up on campuses, telecom compounds and mountain micro-grids — places with a real load, a height limit and neighbours who will notice a noise complaint.
The GH-H10K uses a 4 m diameter, 6 m tall H-rotor — 24 m² of swept area — on a 9, 12 or 15 m tower, with a disc-type coreless permanent-magnet generator at the base. Cut-in is 2.2 m/s, rated wind speed 11 m/s, survival 45 m/s, and the whole machine runs at 45 dB with IP55 protection from -50 °C to +60 °C.
On a 5.5 m/s site it produces around 15,500 kWh a year. That is not a number to compare with a 10 kW horizontal axis machine on paper — the H-rotor gives up 20–30 % of the yield. It wins instead on the things that decide whether a project happens at all: no yaw mechanism to service, no tail vane to break, a 45 dB signature, and a rotor that keeps working when the wind shifts 90° between gusts.

Price depends on tower height, controller and battery bank — ask for a quote with your site details.
Five aluminium-alloy blades with two inner blade layers. Tip speed stays low, so the machine is quiet and the blade erosion rate is low.
No iron core means no cogging torque, so the rotor starts in 2.2 m/s instead of waiting for 4 m/s. Generator efficiency stays flat across the speed range.
The specification that gets a wind turbine approved on a campus or beside a warehouse: it is quieter than the HVAC plant on the same roof.
A free-standing tubular tower keeps the footprint to a 3 m base — useful on sites where guy anchors would cross a boundary or a car park.
Carries a 2–4 kW radio load with a 48 V battery bank, and survives the gusty, dirty wind that makes a HAWT furl constantly.
A visible renewable asset that also produces 15 MWh a year against a building's baseload — and stays below the noise limit at the boundary.
Pairs with 10–15 kW of PV and a 40 kWh battery, where the wind arrives from three directions in an hour.
