Introducing WFD7.5KW – 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 WFD7.5KW is used to charge 120V or 240V 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 WFD7.5KW 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: 67.2~80.1 dB
• Background Sound Pressure Level at 7.3~8.7 m/s: 52.3~64.1 dB
• Different between background and turbine : 14.9~16.0 dB

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.
