Abstract

Automatic transfer switches (ATS) have the potential to be important in ensuring uninterruptible power supply across a wide range of sectors, enabling smooth transitions between utility and emergency RES power sources, generators, and more. Utilizing DC electricity provides a cost advantage and is suitable for short-distance transmission. The author proposes a 12-volt DC backup system that corresponds to a minimum input voltage of more than 10 Vdc and can be applied in various DC load applications. The ATS design incorporates multiple inputs and uses algorithms to prevent simultaneous operation of all sources and reduce feedback. These developments in backup system technology, coupled with the shift to renewable energy, are contributing to the creation of a sustainable and resilient electricity grid. In experiments, the ATS system demonstrated its ability to provide 24 hours of backup power with a specified load (lighting bulbs, light-emitting diodes (LEDs), motors, and fans) discharging 0.27–2.25 Amperes. Using the millis programming language, it supports the performance of a constant switch transition speed of around 0.6453 seconds for a switch from buck to SCC. 0.658 seconds for solar charge controller (SCC) to power supply (PSU), 0.656 seconds for PSU to CC PSU, and 0.61 seconds for PSU to OFF.

Abstract

Solar Power Plants (PLTS) are an environmentally friendly alternative source of renewable energy, especially in tropical regions like Indonesia. PLTS offers an ideal solution to support electrification in areas that are difficult to reach by the power grid, such as the shrimp pond in Banjarasri, Tanggulangin, Sidoarjo. This pond, covering approximately 2 hectares, utilizes PLTS to meet energy needs, particularly for nighttime lighting. However, one of the main challenges in operating PLTS is the limited real-time performance monitoring system. Failure to detect a drop in panel efficiency, damage to the solar charge controller, or battery overload can lead to energy loss and high maintenance costs. This study examines the implementation of a PLTS monitoring system using an SD Card-based data logger as an affordable and independent solution without relying on internet connectivity. The system has been tested to record parameters such as battery voltage, charging current, load current, and load voltage. Measurement results show that deviations between SD Card readings, Serial Monitor, and manual measuring instruments are very small (±0.01–0.3), demonstrating the system’s accuracy and consistency. With the support of an RTC module, data timestamping also runs synchronously and stably. In conclusion, integrating PLTS with an SD Card-based monitoring system proves effective in supporting efficient and sustainable shrimp pond operations. This technology enables early detection of system disturbances, faster technical decision-making, and long-term operational cost savings.
