Main Parameters:

5kw household variable pitch wind turbine manufacturer, China supplier-SENWEI ENERGY as the best quality small wind turbine generator manufacturer, already has a good reputation abroad, especially in European countries such as Italy, France, Britain, Ireland, Austria, Poland, Denmark and so on. They praise the technical stability of our SWT-5KW variable pitch wind turbines. They are familiar with the operation of our pitch controlled wind turbines and the solutions of this type wind turbines. Therefore, our products have won the favor of many customers from Europe.

SWT-5kw pitch wind turbine is the first down-wind centrifugal force controlled passive variable pitch wind turbine system designed and manufactured by SENWEI Energy company that follows BWEA standard. It meets IEC61400-2 (ClassⅡ) design requirements for small wind turbine and obtained MCS (Microgeneration Certification Scheme) Certification in Oct 2012. SWT-5kw pitch controlled wind turbine is one of the variable pitch wind turbine series supplied by SENWEI together with 2kW, 10kW, 20kW and 30kW. Product quality has been well controlled by following ISO9001 standard. Ever since accessed to the international market in 2008, it has performed excellently with good power generating, durability, safety, quick installation, easy maintenance, compact structure and streamline appearance.

In recent years, due to the low cost of photovoltaic system with cheap solar panels, this situation also forces us to produce better quality and cheaper wind turbine generators to meet the current market, to solve the market bottleneck of small wind turbine, so that users can use better and higher quality small wind turbines with low cost. The system enables users to afford pitch controlled wind turbines and install variable pitch small wind turbines. At the same time, it caters to the photovoltaic system and works with it to build wind-solar complementary system, so that the entire alternative energy system can be more perfect and more benefit for the end-users, so that customers feel that is no longer at risk if they invest in alternative energy.

SWT-5KW variable pitch controlled wind turbine is composed of pitch blade, permanent magnet generator, rotary body(including the slip ring and mechanical braking device), tower, braking switch,electric controller, battery bank, inverter, cable, etc. It has adopted the mechanical variable blade pitch technology. When the blade is static, it can be started easily; as soon as the wind speed reached 3m/s, the rotor will begin to rotate. Within the wind speed of 4-11m/s, driven by the centrifugal force, the blade will change it’s position gradually, tracking the relative high lift over drag ratio for the better running efficiency; When the blade is rotating fast, the centrifugal hammer will draw the blade backward towards it’s original position, keeping the blade running with the rated speed, the maximum rotation speed would be no more than 280r/min.

Downwind type, without tail vane.All of the exposed components have experienced a long effecting anti-corrosion treatment to protecting the exposed parts in open air.

Purpose:
Off-grid small wind turbine system: the power generated by the turbine will be converted and charged by controller into the battery bank, and this will power the load:such as lighting,household appliance, dynamic equipment by an inverter.

On-grid small wind turbine system: the power generated by the turbine will be converted by controller and feed back to the grid system through an on-grid inverter.

l Structure Dimensions

l Variable Pitch Mechanism: Blade angle is positive 15 degree as factory setting at which the turbine is easy to start spinning. After the turbine getting running ,the angle of blades turns to 0 degree quickly, and the blade acts at its most efficient point (one spring acts). It outputs 5kW electrical power at 11m/s wind speed with 240 rpm rotor rotation speed. If the wind speed increases,the blade is forced to turn towards negative angle by centrifugal hammers to limit rotation speed (two springs act). The springs balance the blades angle and rotation speed while regulating power generating.
