The wind energy is another option to produce electricity. Because the wind generators produce directly 12, 24 or 48 volts of direct current, can be used directly in applications pumping water or electricity stored in a bank of batteries for later use
Perhaps the most famous product of solar energy are the photovoltaics. The main advantage is its use is the steady energy production, its long life and minimum maintenance.
The inverter is a basic component in photovoltaic systems of middle or higher capacity, these convert direct low-voltage current from the batteries in high voltage current.
