Abstract

Access to reliable and sustainable electrical energy remains a challenge for coastal communities in Indonesia, especially in areas not yet served by the national grid. This study presents the design and implementation of a standalone solar power system (PLTS) integrated with Internet of Things (IoT) technology for lighting applications on a floating raft house in Manado City. The system consists of two 250 Wp solar panels, a 24V 100Ah LiFePO4 battery, an MPPT solar charge controller, and IoT-based remote monitoring and control using the Blynk application. Performance testing was conducted to evaluate the battery’s charging and discharging behavior over a 24-hour cycle. Results show the system fully charges in 6 hours with an average charging efficiency of 91.5% and energy utilization efficiency of 85.3%. The system supplies lighting for 11.2 hours at 175–200 W. IoT integration enables real-time monitoring of voltage, current, and remote switching. The testing was conducted only for a short duration under fair weather conditions, and therefore did not evaluate long-term durability or the potential for system scalability.
