Abstract

Renewable Energy (RE) is one of the energy sources widely used to meet the continuously increasing demand for electricity while reducing the use of depleting fossil fuels. Off-Grid Solar Power Plants (PLTS) are part of RE that utilizes solar energy as the primary energy source. In such systems, batteries often present a common issue, particularly due to damage caused by excessive power usage and Depth of Discharge (DoD) exceeding predetermined limits. Therefore, this study aims to design and build a battery protection system to prevent excessive power usage and manage DoD. The protection system allows for the regulation of power usage and DoD of the battery according to set parameters. Furthermore, in tests with incremental loads, the relay starts to activate at specific current and power levels. In the experiment with a 21.70-W load, the relay remained off; however, when the power reached 70.86 watts with a larger load, the relay activated to protect the battery. Based on this research, the protection system can be applied to off-grid PLTS systems that use batteries as temporary storage for electrical energy generated from solar panels. The conclusion of the developed system is that this protection system successfully provides battery protection by cutting off the electrical flow when the power exceeds the set limit and the battery’s DoD reaches the specified threshold. This system can be applied to off-grid PLTS to prevent battery damage due to excessive usage, extend battery life, and improve the reliability of RE systems. Thus, this system contributes to the development of more sustainable and efficient RE.
