ABSTRACT

 One ofthe basic needs ofhumans is electricity andfor electricity to be available, a source of generating electricity needs to be made available. The purpose ofthis project is to design and construct a 5KVA solar powered Inverter at afrequency of50Hz. This device is constructed with locally sourced components and materials ofregulated standards. The basic principle of its operation is a simple conversion of 12V DCfrom a batteiy using integrated circuits and semiconductors at afrequency of50Hz, to a 220VAC across the windings ofa transformer. An additional power supply to the public power supply with the same power output is thus provided at an affordable price. Solar inverter converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use ofordinary ACpowered equipment. In solar inverter, Solar panels produce direct electricity with the help of electrons that are movingfrom negative to positive direction. Most ofthe appliances that we use at home work on alternative current. This AC is created by the constant back andforth of the electrons from negative to positive. In AC electricity the voltage can be adjusted according to the use ofthe appliance. As solar panels only produce Direct current the solar inverter is used to convert the DC to AC
