Abstract

This paper presents the design and implementation of 1000VA Inverter System with Internet of Things (IoT) that helps to ameliorate the impact of the excruciating economic hardship. especially on Small and Medium Scale Enterprises (SMEs) that largely depends on electricity for survival amidst energy crises, scarcity and rise in premium motor spirit price in Nigeria. The inverter system was designed using two microcontrollers, ATMEGA328P and NodeMCU. The ATMEGA328P is responsible for the generation of the sine pulse width modulation (SPWM), control and stability operation; while connection for wireless monitoring and control is carried out by NodeMCU. The features of the inverter pure sine wave output, stable output voltage of 220V ± 2.36% and output frequency of 50Hz ± 0.3% were obtained from the tests carried out on the system. The inverter system has short-circuit protection, overload protection, state of charge battery monitoring and protection, automatic changeover as well as monitoring and control using connected mobile devices and computer system. The inverter designed and built is scalable as the capacity can be increased to the load demand of the user, and thus it .is suitable for industrial, commercial and residential use.
