DESIGN AND IMPLEMENTATION OF SOLAR INVERTER

A solar inverter converts the variable direct current (DC) output of a photovoltaic (PV) panel into alternating current (AC) that can be fed into a commercial electrical grid or used by local, off-grid electrical networks. It is a critical balance of system (BOS) component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for photovoltaic arrays and maximum power point tracking systems. While running the appliances in day time, the device will charge the battery because the solar energy only can be used during the day time, while during night the battery will support to run the appliances until next morning. Consumer can check Voltage and Current on device via the Liquid Crystal Display. Once consumer compare the off grid system from main power source, consumer will understand the power usage and also differentiate the cost. At the end of this project, inverter also provides 230V single phase same as power delivered by the grid, but the cost will be totally different.
