This project describes the design and implementation of an automatic transfer switch system which can help to save energy and reduce greenhouse gases. The main concept that ultimately led to the creation of this project originated in the field of energy management. In Malaysia, the use of fossil fuels to generate energy is expanding day by day and Malaysia's power usage is also increasing annually. One of the primary causes of this problem is that the vast majority of Malaysian households rely solely on grid�connected energy sources 24 hours. As a result, energy is wasted, and customers end up paying more for their electricity. Thus, this project responds to all these challenges by providing the solution to the household that intends to reduce the energy consumption as well as the electricity bill with the installation of a solar PV system. The name of this device is Solar PV Automatic Transfer Switch for Electrical Energy Management. In this project, the utility grid acts as the primary source while PV system acts as the secondary source. The changeover phase will begin based on the predefined time in Arduino IDE. The vital components for this switching phase are the DS3231 RTC, Arduino Uno, and 1-Channel 5V relay. Besides, PZEM-004T are employed to read the parameters of the load, whereas ESP32 is utilised for data transport. Users can monitor the load's parameters via the Blynk application and LCD display. As observed, the total energy consumption for a house without energy management is 0.54kWh per day while for the household with ATS is 0.279kWh Per day. The total energy usage of ATS-equipped households is lower than a typical household. One of the key advantages of this system is that it provides a secure, sensible and readily adaptable system that gives the user with a smart household monitoring.
