FD4-4kw Wind turbine Generator:

Horizontal axis wind turbine 4kw off grid system: 

4kw wind turbine converts wind energy to 3 phase AC unsteady power. Off grid charge controller converts 3 phase AC power to DC and charge to battery group. Inverter converts DC power to 220vac 50hz or 110v 60hz to supply AC load use. 

Horizontal axis wind turbine 4kw on grid system: 

4kw wind turbine converts wind energy to 3 phase AC unsteady power. On grid controller converts 3 phase AC power to Dc and supply to grid tie inverter.  Grid tie inverter feeds single phase/3 phase power to grid power. 

4kw wind genrator can supply lighting, TV set, the searchlight, the communication equipment, the power tool and other household appliances.
