Abstract

Ketergantungan terhadap energi fosil menuntut pemanfaatan energi alternatif. Fluktuasi matahari dan perpindahan daya manual sering membuat pasokan Pembangkit Listrik Tenaga Surya (PLTS) tidak stabil. Penelitian ini bertujuan merancang sistem PLTS off-grid dengan mengintegrasikan inverter DC ke AC dan Automatic Transfer Switch (ATS) berbasis ESP8266 guna menjaga kontinuitas suplai energi. Metode Research and Development (R&D) dengan pendekatan VModel digunakan dalam penelitian ini. Perangkat keras meliputi panel surya monocrystalline 600 Wp, baterai VRLA 24 V 100 Ah, Solar Charge Controller MPPT 40A, inverter 1000 W dengan daya puncak 2000 W, dan modul ATS ESP8266. Hasil pengujian menunjukkan sistem beroperasi sesuai skenario pengujian. Sensor tegangan baterai berakurasi 99,81% (error 0,19%). Kemiringan panel optimal untuk daya keluaran tertinggi adalah 15°. Inverter dalam pengujian dengan rata-rata error tegangan AC 3,64%, di bawah batas toleransi (<10%). Modul ATS ESP8266 mampu memantau tegangan baterai secara real-time dan memindahkan sumber beban otomatis dengan jeda 1 detik. Kesimpulannya, sistem PLTS sesuai skenario pengujian dan kontinuitas listrik sesuai skenario pengujian. The dependence on fossil energy demands the utilization of alternative energy. Solar fluctuations and manual power transfer often cause instabilities in the supply of Solar Power Plants (PLTS). This research aims to design an off-grid PLTS system by integrating a DC-to-AC inverter and an ESP8266-based Automatic Transfer Switch (ATS) to maintain the continuity of the energy supply. The Research and Development (R&D) method with a V-Model approach was used in this study. The hardware includes a 600Wp monocrystalline solar panel, a 24V 100Ah VRLA battery, a 40A MPPT Solar Charge Controller, a 1000W inverter with a 2000W peak power, and an ESP8266 ATS module. The test results show that the system operates according to the testing scenarios. The battery voltage sensor has an accuracy of 99.81% (0.19% error). The optimal panel tilt angle for the highest power output is 15°. In testing, the inverter showed an average AC voltage error of 3.64%, which is below the tolerance limit (<10%). The ESP8266 ATS module is capable of monitoring battery voltage in real-time and automatically transferring the load source with a 1-second delay. In conclusion, the PLTS system aligns with the testing scenarios, and the electricity continuity operates according to the testing scenarios.
