20KW Grid Tie Wind Generator

WFDG20

Reduce or Eliminate Your Electricity Bill

Reduce or Eliminate Your Electricity Bill
Introducing WFDG20 – A new generation Residential Power Appliance that hooks up to your home to help you reduce or eliminate your monthly electricity costs.

WFDG20 is designed for homeowners looking for a quiet, convenient, affordable way to protect themselves from ever increasing electricity costs. It includes wind generator, controller with dump load and grid tie inverter. With no batteries, WFDG20 connects directly to your home. When the wind is blowing, your home is powered (in part) by WFDG20; when it’s not, your home is seamlessly powered by your utility as usual.. If the wind speed is too large, part of the dump load will be connected to the wind turbine to keep the constant power to fed in the utility grid.

And you do not need the most disposable part of a wind power system --- the batteries. Without the repeated purchase of batteries.

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.
