The purpose of this research is to have an affordable and clean energy supply in our household. Inadequate power supply in Nigeria has been a major challenge bedeviling our institutions. Some areas connected to the distribution companies (DISCOs) have what is referred to as a regimented load shedding where power supply may range from 6.00 to 12.00 hrs within 24 hrs. Homes and offices have resolved to sourcing for alternative power supply such as generator plants, solar PVs, inverters, etc. Thus, the 2.5KVA inverter system was proposed to serve as a backup once there is power outage from the DISCOs. An inverter system enables the conversion of direct current (DC) from batteries to alternating current (AC) needed to run the office appliances at a minimal cost and optimal efficiency. The project focuses on the design and construction of a pure sine wave 2.5KVA 50Hz inverter system to deliver 220V AC using 2 Nos 12V DC batteries (rated 200A) connected in series.
