Product Description The On grid wind turbine system is composed of wind turbine, on grid controller, on grid inverter, metering device, and power distribution system. Wind energy is converted into AC electrical energy by the wind turbine, and then converted into DC electrical energy by the on grid controller, and then DC electrical energy is converted into AC electrical energy of the same frequency and phase as the grid by the on grid inverter, and part of the power is supplied to the local load. Surplus power is fed into the grid.Wind Turbine1. High standard ,quality components for use in harsh and extreme environments for wind turbines .2. Low wind speed model,has electric brake ,overcharging protection,stable output voltage comes with charge controller .3. High efficiency and low mechanical resistance energy loss.4. Excellent heat dissipation due to the aluminium alloy outer frame and special internal structure .5. High strength from the fully heat treatment aluminium,anti-corrosion and weatherproof6. Generator is designed using special material and treated to resist corrosion and oxidation.7. Designed for reliable and long operational lifetime under long-term full output .8. Designed for 20-years operation life .9. Patent protected design.Product Details:1. Imported NSK BearingThe generator adopts NSK bearing, which can withstand up to 7000rpm, ensuring the normal operation of the generator for a lifetime.2. Pure Copper Enameled WireWith insulating paint as insulating coating, the copper wire used for winding the electromagnetic coil is resistant to high temperature to ensure the power generation of the windings.3.NdFeB MagnetGenerator magnetic steel model: N35SH, resistance to 150°C lifetime demagnetization, known as the king of magnetism.4. Pure Copper Electric Slip RingSlip-ring copper content of more than 85%, basically no wear, fan life operation, no maintenance.5. Convenient Flange DesignUse humanized flange design, easy to maintain and install.ModelDMFD4-3.0KWRated speed(r/min)350r/minRated power(KW)3KWRated voltage(DC/V)48,96, 110 VDCRated current(A)36,18,15.8 AStart-up wind speed(m/s)2m/sRated wind speed(m/s)9m/sSafe wind speed(m/s)40m/sNo of blades3 piecesMaterial of bladesreinforced fire glass steelGenerator3 phases PM generatorBraking systemElectromagnetic braking controlWind turbine weight(kg)68kgPacking weight(kg)85kgTower height(customized)pull rod and independent rodTechnical Parameters of the On Grid Wind Turbine Controller 3KW TypeFKJ-GT 3KWWind turbine rated power3KWWind turbine Max. power6KWWind turbine rated voltageAC220VFunctionRectifier,control, DC outputAutomatic protection functionOver voltage protection, network electric cut off protection, regulated supply output, arresterManual functionManual brake, reset, emergency switchDisplay modeLCDDisplay contentWind turbine voltage, current, power; Solar voltage, current, power; DC output voltage, DC output current, DC output power, total power.PWM constant voltage≥320dcwind turbine 3-phase dump load voltage350±5VdcTime-lapse of the wind turbine 3-phase dump load12-20 minPWM dump load fuse16AFuse of DC output20AWork environment temperature-30-60°CRelative humidity<90% No condensationNoise (1m)<40dBDegree of protectionIP20(Indoor) Cooling methodForced air cooling*Communication interface (optional)RS485/USB/GPRS/WIFI/EthernetSize of the controller (mm)560*430*320Weight of the controller18KgSize of the dump load (mm)500*460*330Weight of the dump load10Kg*Above parameter only for reference 1.
