PROJECT DESCRIPTION

The solar energy is converted to electrical energy by photo-voltaic(PV) cells.This energy is stored in batteries during the day time in order to be utilized whenever required. This project is designed to use solar energy for household loads using Inverer.

This project deals with a controlled charging mechanism which protects over charge, deep discharge and under voltage of the battery.A solar inverter, or PV inverter, converts its direct current (DC) output of a photovoltaic  solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-line electrical network.   

 In this project, the solar energy is stored in the battery from Photo Voltaic cells. This stored energy of  battery is converted in of linemode to AC supply of 50 Hz frequency using PWM inverter IC with MOSFET gate by driver IC to driver a half MOSFET bridge and a step-up transformer.

A set of op-amps are used as comparators to continuously monitor panel voltage, load current, etc. Indications are also provided by a green LED for fully charged battery while a set of red LEDs indicate under charged, overloaded and deep discharge conditions.

Charge controller also uses MOSFET as power semiconductor switch to ensure cutting of the load in low battery or overload condition. A transistor is used to bypass the solar energy to a dummy load while the battery gets fully charged. This protects the battery from getting over charged.    

 Furthermore, the project can be enhanced by using microcontroller and GSM modem to communicate the status of the system to a control room via SMS.
