7.5KW Grid-Tie Wind Generator

WFDG7.5

Reduce or Eliminate Your Electricity Bill

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.
