7.5KW Grid-Tie Wind Generator


Reduce or Eliminate Your Electricity Bill

Introducing WFDG7.5   – A new generation Residential Power Appliance that hooks up to your home to help you reduce or eliminate your monthly electricity costs.

WFDG7.5  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, WFDG7.5 connects directly to your home.  When the wind is blowing, your home is powered (in part) by WFDG7.5; 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, The house will use the electricity from the system first, and if needed from the utility.
