When you decide to install a wind system in your house, there are a number of wind installation systems that are available and they depend much your nearness to the power line.
The 3 common installation systems are:
Grid Connected with battery backup
The Grid Connected involves the wind turbine produces power (AC) which is fed into the house. Should the wind turbine produce more power than the demand of the house, this excess power is fed into the Grid via a meter which counts the units fed into the grid. On the other hand, should the wind system produce less power, the breaker box, shuts and opens power from the grid to be used. The Grid Connected with battery back-up is similar to the Grid Connected but inclusive of a battery. This battery is the storage of energy when the wind system is producing more power. In the event of a black-out energy from the battery is used. For the case of Off-Grid, the system is installed in places where the power grid is not available. It has batteries for harnessing excess power from the wind turbine.
In the next post we shall look in detail at the 3 systems.
