Abstract

The development of solar power plant (SPP) technology presents an effective solution for providing electrical energy in remote or off-grid areas, particularly through the use of portable solar systems. This study discusses the design and implementation of a portable solar power generation system utilizing solar panels, a solar charge controller (SCC), a battery (accumulator), an inverter, and the integration of an ESP32 microcontroller with a PZEM-004T sensor module for real-time monitoring via the Blynk IoT platform. The system converts solar energy into electrical energy, stores it in a battery, and supplies it to AC loads through an inverter.

The test was conducted to evaluate the accuracy of voltage and current measurements using a multimeter as a standard. The voltage sensor showed a slight deviation from multimeter readings with error percentages ranging from -0.0013% to -0.0057%. The current measurements remained stable with a consistent error of -0.66%. These results indicate that the sensor modules provide reliable data for monitoring purposes, validating their application in portable and renewable energy systems. The integration of IoT-based monitoring enhances usability and system reliability, especially for outdoor or mobile applications such as camping or emergency backup power.
