A 40ft open top container can hold 8 units. (excluding the tower)
Vh model has small size, and simple design. It fully uses lift force, easily products rated power at low wind speed. 3 phase permanent magnet ac generator, direct driven, no gearbox, and not need windward.
It has perfect performance. With low rpm of generator; controller can be pwm, on grid; invertor can be pure sina wave with automatic on-grid interface or directly on grid invertor.
1.Magnetic saturation generator design, 20years designed life.
2.2-2.5m/s start-up wind speed under low torque start-up technique.
3.Independent power supply
4.Blades are casted into molding at one time with balance up to 99%.
5.Bearings import from japan (nsk), long service time (5 years maintenance-free).
6.Low cost and low noise
7.Low cut in wind speed (3m/s) to guarantee the maximum generation at low wind speed.
