Ampair Pacific12Volt 300Watt Marine Wind Turbine

Ampair 12Volt 300Watt Marine Wind Turbine


The design of the Ampair 300 combines modern styling with low visual impact and quiet operation. It is suitable for larger yachts, small industrial & scientific locations, or remote holiday cabins. This micro wind turbine has evolved from the outstandingly rugged Ampair 100 unit with the addition of the revolutionary PowerFurl™ blade pitch control system, advanced aerodynamic blade design and a more powerful generator.


The accurate aerofoil construction of each turbine blade minimizes noise and vibration optimising performance and improves the power to weight ratio. The rigid blade design avoids “whooping”, “motor boating”, or “screaming”, (vibration, resonance and flutter).


PowerFurl™ technology


Automatic pitch control provides a smooth control of turbine speed in strong winds whilst continuing to generate. The Ampair 300 operates without the need for thermal cutouts, chokes, commutatorbrushes or complex control electronics.




An integral sealing system protects internal components from condensation and corrosion. Revolutionary PowerFurl™ hub runs on low friction polymer bearings for long life with no lubrication requirement. Throughout the design all components are selected for corrosion resistance and durability -all our turbines are marine grade.




A powerful, low-speed alternator converts the turbine motion to 3 phase AC electricity. This allows use of lighter cables to feed the regulator whilst minimising voltage drop and power loss.




Engineered to be smooth running, quiet and vibration free the Ampair 300 benefits from a pedigree stretching back well over 25 years.
