Abstract

The development of grid-tied photovoltaic (PV) systems in tropical regions remains a strategic focus for achieving sustainable clean energy. However, energy conversion efficiency is often hampered by fluctuations in panel surface temperature and electrical faults. To ensure long-term system reliability, this study implements a multi-level redundancy architecture integrated with dynamic internet of things (IoT) monitoring for fault mitigation in grid-tied PV systems. The system employs a machine learning (ML) method using the k-nearest neighbors (KNN) algorithm for thermal classification, achieving an accuracy of 84% in identifying normal (25 °C to 35 °C) and overheating conditions. Furthermore, an electrical redundancy layer is designed with an automatic tripping mechanism that activates when the current exceeds a 1.30 A threshold, demonstrating a rapid response latency of 150 ms. To ensure monitoring resilience, the system is supported by a dedicated 18650 Li-ion battery backup. The implementation results confirm that this multi-level protection framework effectively monitors real time energy usage, prevents critical component damage, and enhances the overall safety of household-scale PV installations. This research provides a scalable and intelligent solution for fault mitigation, supporting the broader adoption of renewable energy in tropical environments.

Abstract

Partnerships between universities and partner institutions are strategic for study program accreditation and for implementing the Tri Dharma of Higher Education. In 2025, Al-Azhar University established an international collaboration with Universiti Malaysia Perlis (UniMAP) and the Village Forest Management Institution (LPHD) of Pasar Rawa, Langkat Regency, in the field of community service. The activities included a networking session, strategic discussions on converting palm oil plantations back into mangrove forests, and a joint mangrove planting action. This initiative aims to restore coastal ecosystems as habitats for marine life, such as fish, crabs, and shrimp. Through this synergy, it is expected that the motivation of the Pasar Rawa Village community, particularly the LPHD, will increase in managing and preserving the mangrove area sustainably for the welfare of the coastal ecosystem.
