WFD3KW
Introducing WFD3KW – A wind generator with beautiful shape, safe, portable and reliable. It is especially designed to meet the demand from individual householders for a renewable energy source.
The WFD3KW is used to charge 48V/ 120V batteries. Equipped with suitable DC to AC inverter, it is capable of supplying power for:
Refrigeration
Electric fan
Lights
Air conditioner
Communication equipment
When used in conjunction with a suitable Grid Tie inverter WFD3KW can also be connected to the power grid.
Features:
Reliable passive self furling
Autobrake slows down the blades spin when the batteries are charged
Marine quality powder coated aluminium body, water tight housing
Iron Boron Neodymium magnet alternator.
Reliability: The design of the body efficiently flows excess heat into the wind reducing operating temperature
Two years warranty; operational life expected to be in excess of 15 years.

Apparent Sound Power Level for the Acoustic Reference Wind Speed
-
Turbine Sound Pressure Level at 7.3~8.7 m/s: 69.7~85.2 dB
-
Background Sound Pressure Level at 7.3~8.7 m/s: 54.6~66.8 dB
-
Different between background and turbine : 15.1~18.4 dB
Test was made at 10 meters from the turbine.
Electrical Installation
1) On Grid Connecting
2) Off Grid Connecting
In most cases the loads will be AC(alternating current) and they will be supplied through a DC-to-AC inverter.
