Product Description

Type: 3 Blade Upwind Rotor Diameter: 2.7 m Start-up Wind Speed: 2.5 m/s (5.6mph) Cut-in Wind Speed: 3 m/s (6.7 mph) Rated Wind Speed: 8 m/s (*7.9 mph) Rated Power: **0 Watts Maximum Power: ~ **0Watts Furling Wind Speed: *3 m/s (*7 mph) Overspeed Protection: AutoFurl Temperature Range: **0 to **0 Deg. C (**0 to ***0 Deg. F) Generator: Permanent Magnet Alternator Output Form:*6 VDC/*4VDC Nominal Work principle and features Working principle: Wind energy is used as the motive power to provide low speed rotation of a permanent magnet generator to produce alternating current which is then converted to direct current by a controlled constant voltage rectification system, the resulting voltage being stored in a battery, or batteries. The direct current from the battery, (batteries), is then converted to alternating current by an inverter, the resulting controlled and stabilised alternating current being used to power the load, this is the general principle for battery storage type systems. Grid connect systems take the alternating current produced by the turbine directly to an inverter which controls and stabilises the alternating current and also provides numerous control elements for direct connection to the electricity grid. Features : The products combine unique and innovative design with high reliability. The innovative design has been awarded both Invention and Practical new patents by the State Intellectual Property Department and thereby has totally independent property rights in China, resulting in the market leading position in wind to electrical energy conversion, technical design and efficiency. Key design features such as very low rotation speed result in increased efficiency in comparison to other small turbine systems.
