Wind Generator
WKD20KW
Introducing WFD20KW – 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 WFD20KW is used to charge 240V or 360V 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 WFD20KW 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
