Penggunaan Pembangkit Listrik Tenaga Surya (PLTS) sebagai alternatif energi dari matahari telah menjadi solusi vital untuk kebutuhan listrik rumah tangga. Namun, sebagian besar sistem pemantauan PLTS saat ini hanya dapat diakses dari lokasi pembangkit, membatasi akses informasi bagi pengguna. Penelitian ini bertujuan untuk mengembangkan sistem pemantauan real-time menggunakan Internet of Things (IoT) pada sistem PLTS Off-Grid. Sistem ini memantau komponen Photovoltaic (PV), baterai, serta input dan output inverter, dan memungkinkan pengendalian inverter. Dengan mikrokontroler Arduino UNO R3, ESP32, sensor PZEM-004T, sensor arus ACS712, sensor tegangan, sensor suhu DHT11 dan relay, serta aplikasi Blynk dan ThingSpeak, informasi terhubung ke jaringan internet, memberikan akses kepada pengguna untuk memantau dan mengendalikan kinerja inverter secara real-time melalui perangkat seperti smartphone. Berdasarkan penelitian, sistem ini berhasil mengintegrasikan pemantauan real-time terhadap parameter penting sistem PLTS Off-Grid, seperti arus, tegangan, daya, dan suhu PV, yang terbukti dengan pengambilan data sensor dari hari pertama hingga hari ketujuh. Selain itu, sistem ini juga berhasil mengembangkan kontrol inverter yang terintegrasi dengan IoT, dibuktikan dengan data kontrol on/off inverter, di mana pada hari pertama relay menerima sinyal off pada pukul 07:00:22 dan sinyal on pada pukul 19:00:17, serta pada hari kedua sinyal off diterima pada pukul 07:00:21 dan sinyal on pada pukul 19:00:13.

The use of Solar Power Plants (PLTS) as an alternative energy source from the sun has become a vital solution for household electricity needs. However, most current PLTS monitoring systems can only be accessed from the plant's location, limiting user access to information. This research aims to develop a real-time monitoring system using the Internet of Things (IoT) for Off-Grid PLTS systems. The system monitors Photovoltaic (PV) components, batteries, as well as inverter input and output, and allows for inverter control. Using the Arduino UNO R3 microcontroller, ESP32, PZEM-004T sensor, ACS712 current sensor, voltage sensor, DHT11 temperature sensor, and relay, along with Blynk and ThingSpeak applications, the information is connected to the internet, providing users with the ability to monitor and control inverter performance in real-time through devices such as smartphones. Based on the research, this system successfully integrates real-time monitoring of key parameters in the Off-Grid Solar Power System, such as current, voltage, power, and PV temperature, as evidenced by sensor data collection from day one to day seven. Additionally, the system successfully implements IoT-integrated control of the inverter, as demonstrated by the on/off control data, where on the first day, the relay received an off signal at 07:00:22 and an on signal at 19:00:17, and on the second day, the off signal was received at 07:00:21 and the on signal at 19:00:13.
