Energy demand and consumption increase astronomically as the days unfold. This development has made the deployment of nat ural and renewable energy sources, such as solar, inevitable. They serve as alternative to the inadequate supply of the conventional sources. It is the increasing need for various homes, institutions and firms to embrace the essence of Photovoltaic (PV) system that necessitated this project study. The research work, titled ‗Design and implementation of a 2.5kVA inverter for a three-bedroom apartment‘, was aimed at ensuring that the operations and efficiency of a Photovoltaic system, particularly the 2.5kVA type installed in a threebedroom apartment is well installed and enhanced. To achieve this, a 2.5kVA Hybrid Power Inverter with integrated 50A PWM charge controller which is used to regulate the charging and two 12V batteries of high Depth of Discharge were used, 6 200W solar panels were also used. The batteries and solar panels were connected in series/parallel arrangement for effective utilization. This also involves load sizing, inverter sizing, PV panels sizing and charge controller sizing. The hybrid Inverter (multi-mode), which produces a pure sine wave in the process, guarantees reliability and cleaner output as expected. At the end of the research, an implementation of a 2.5kVA Solar Home System was actualized.
