This work is on the design and construction of a 2.5KVA solar inverter. 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 of ordinary AC-powered equipment. In solar inverters, Solar panels produce direct electricity with the help of electrons that are moving from a negative to a positive direction. Most of the appliances that we use at home work on alternative current. This AC is created by the constant back and forth of the electrons from negative to positive. In AC power, the voltage can be changed depending on how the equipment will be used. Solar inverters are used to convert DC to AC because solar panels can only produce Direct Current. A 2.5KVA electrical inverter was designed for this project. The inverting circuitry assembly's architecture has two 200Ah dry cell batteries, a 240v/24-0-24v center-tapped transformer, and electrical and electronic components. A refrigerator (1200 watts), four high-energy lights (40 watts each), a standing fan (60 watts), a television (200 watts), a DVD player (240 watts), and a 60-watt tungsten lamp were all powered by the design electric inverter. At the stated load of 1940 watts, the inverter lasted for roughly five hours
