Design and Implementation of Automated Switching and Real-Time Monitoring of Hybrid Solar System

Abstract

This paper demonstrates a designed prototype of an instant power supply scheme to assure continuous output current to load in housing application to utilize both renewable energy and Grid. The design procedure and performance evaluation an improved quality “Arduino” based smart switching controller for a hybrid solar system. Based on a programmable algorithm, a smart switching controller was designed using a relay and voltage sensing element for cost-effective operation within the grid-tied solar system and reducing power consumption from the grid. The switching controller controls the power supply to the load by confirming the availability of the solar, battery and grid. The implemented automatic Switching system demonstrates that it has the capability of automatic switching and acceptable performance for grid-connected Hybrid Solar System. At nominal voltage output and frequency, the inverter output has been simulated in MATLAB/SIMULINK. A real-time online WiFi module and LCD based monitoring circuit have been developed and adapted to monitor the whole system for the efficient operation of the system.
