The requirement and use of electrical energy is increasing rapidly with technology development and population growth. By using renewable and non-renewable sources, electrical energy is generated. Multiple advantages of solar energy are the key factors behind the usage of solar charge controller for various purposes in industrial applications. Solar charge controller is used for storing the electrical power in batteries which is  generated with the help of solar panels and further it can be fed into loads.

A solar charge controller is basically a current or a voltage controller to charge the battery and to protect the cells from overcharging. It directs the current and voltage comes from the solar panels to charge the battery. Generally, 12V panels are put out in the approximate value of 16 to 20V, so in the overcharging condition the electric cells will be damaged if no regulation is provided. For getting completely charged, electric storage devices require14 to 14.5V. The solar charge controller circuits are available in all features, sizes and costs ranges from 4.5A to 60-80A.
