Commercial wind turbine · 30 kW class
Twelve metres of rotor, 113 m² of swept area, and the largest frame we build that still leaves the factory in a single 40 ft container with the tower nested inside. That detail decides more projects than the power rating does.
The GH-A30K is the top of the direct-drive GH-A platform: a 12 m rotor on a 30 kW permanent-magnet generator, 380 V three-phase, rated at 11 m/s with a 3 m/s cut-in. On a 6 m/s site it delivers roughly 71 MWh a year — around 60 % more than the 20 kW model for about 40 % more money, which is why most buyers who hesitate between the two end up here.
Its real advantage is logistics. The nacelle, three blades and the 30 m tower section all fit in one container, so a project in a country without a turbine supply chain can be delivered on a standard freight lane and erected with a 25 t crane in two days. A 50 kW machine needs a low-bed trailer, a 50 t crane and a road survey before it can leave the port.

Price depends on tower height, controller and battery bank — ask for a quote with your site details.
Three GFRP blades on a direct-drive PMG. No gearbox, no oil, no slip ring — the annual service is blade bolts, yaw bearing play and tower torque.
Nacelle, blades, tower and controller ship together. This is the cost line that decides whether a remote project is viable.
30 kW grid-tie inverter with anti-islanding, or a hybrid inverter sharing a DC bus with 20–30 kW of PV and a 100 kWh battery.
18, 24 or 30 m galvanised tower with a pre-assembled head. Foundation drawing and lifting plan supplied with the shipment.
Runs a 20 kW cold room and a milling line through the day, when the grid is weakest and diesel is most expensive.
Cuts diesel burn on a 25–40 kW camp load; the battery carries the night, the turbine refills it by ten in the morning.
Pairs with a 22 kW pump on a hill site where the grid connection quote exceeded the cost of the turbine.
Send the site location and the load you need to power. You get a sized model, a price and a lead time — usually within one working day.
