Solar charge controller limits the rate at which electric current is added to or drawn from solar panel to electric batteries. It prevents overcharging and may protect against overvoltage, which can reduce battery performance or lifespan, and may pose a safety risk. It may also prevent completely draining (“deep discharging”) a battery, or perform controlled discharges, depending on the battery technology, to protect battery life. The terms “charge controller” or “charge regulator” may refer to either a stand-alone device, or to control circuitry integrated within a battery pack, solar battery-powered device, or battery charger.

CHAPTER ONE
1.0 INTRODUCTION
Energy plays vital role for development in all sectors. With depletion of fossil fuels used for power generation and increase in demand for power, the gap between supply and demand is becoming more. Renewable energy sources can only provide solution to face this energy crisis. Out of renewable energy options, solar energy is the most potential source for all tropical countries. Sun radiates 180 billion MW of energy over Earth Just one hour of this energy could meet power needs of entire planet for a year. India receives 5000 Trillion KWhrs of energy from SUN per annum. This energy is clean, pollution free and inexhaustible and is available free and in abundance. Basically the components involved in solar system are PV panel, DC-DC Converter, Battery, Inverter.
The PV panel produces electrical voltage/current from solar energy. This solar panel can produce more than the rated voltage to the battery which can be dangerous to the battery due to the high radiation of the sun. In order to tackle the present energy crisis it is necessary to develop an efficient manner in which power has to be extracted from the incoming solar radiation. The use of the newest power control mechanisms called solar charge controller was invented.
Solar Charge controller is basically a voltage and/or current regulator to keep batteries from overcharging.
Solar Charge Controller is fully configurable and developed to meet the highest industry standards to ensure maximal efficiency in retrieving energy from any PV system. When connected to solar panels and batteries, the solar charge controller automatically charges the batteries in an optimal way with all the available solar power. Solar charger controller's sophisticated three stage charge control system can be configured to optimize charge parameters to precise battery requirements. The unit is fully protected against voltage transients, over temperature, over current, reverse battery and reverse PV connections. An automatic current limit feature allows use of the full capability without worrying about overload from excessive current, voltage or amp-hour based load control.
1.1 OBJECTIVE OF THE PROJECT
The objective of this work is to design a device that will maintain the required voltage magnitude coming from solar panel necessary for the load or control the battery voltage supplied from solar panel.
1.2 SCOPE OF THE PROJECT
The main scope of project is, the photovoltaic cells are converting the sunlight in to electricity a charge controller is used. PV cells are bundled together in modules or panels to produce higher voltages and increased power. As the sunlight varies in intensity the electricity so generated usually charges through the charge a set of batteries for storing the energy. Controller in this project is used: To generate the variable PWM for DC-DC CONVERTER, to control the battery voltage and Controlling the load variation.
1.3 SIGNIFICANCE OF THE PROJECT
Solar Charge controller is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.
Solar Charge controller may also monitor battery temperature to prevent overheating. Some charge controller systems also display data, transmit data to remote displays, and data logging to track electric flow over time.
1.4 APPLICATION OF THE PROJECT
Solar Charge controller circuits are used for rechargeable electronic devices such as cell phones, laptop computers, portable audio players, and uninterruptible power supplies, as well as for larger battery systems found in electric vehicles and orbiting space satellites.
1.5 PURPOSE OF THE PROJECT
Use of batteries with solar panels is usually not good. So to avoid failure of batteries before time solar charge controller is used. For example you have a 12 volt battery and you want to charge it with 12 volt solar panel. 12 volt solar panel outputs 17-20 volt. So these 17-20 volt may damage battery due to overcharging, because batteries maximum charging voltage is usually between 13.5-14 volt. To avoid this issue we need to develop a regulator which can control flow of charge from solar panel towards battery. Solar charge controller is used for this purpose.
