3KW Grid-Tie Wind Generator

WFDG3

Reduce or Eliminate Your Electricity Bil

Introducing WFDG3 – A new generation Residential Power Appliance that hooks up to your home to help you reduce or eliminate your monthly electricity costs.

 

WFDG3 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,

WFDG3 connects directly to your home.  When the wind is blowing, your home is powered (in part) by WFDG3; 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.
