Rancang Bangun Control Monitoring Automatic Transfer Switch dari Panel Surya dengan Menggunakan Aplikasi Blynk

Abstract

Automatic Transfer Switch (ATS) is a device used to switch electrical power supplies between two different sources automatically in situations of power failure or unexpected power outages. The aim of this research is to design an ATS system that uses PLTS by blynk application as a controller and monitoring in real time. In this research, an IoT-based ATS control and monitoring system was developed using an ESP8266 microcontroller as well as a Wi-Fi module, a relay as a power source switch, as well as a voltage sensor and PZEM-004T sensor as a voltage sensor. This system uses the main source from PLN and a backup source from PLTS. This system can be controlled and monitored remotely using the blynk application which is connected to the database. The results of the ATS test are functioning well, ATS will move the main electricity source from PLN to PLTS or vice versa very quickly. A battery voltage that has a lower limit of 11 V will disconnect the battery when the voltage is <11 volts. The 10Wp solar panel and 7Ah battery are capable of supplying a load of around 20 watts for more than 4 hours.
