Implementación de un sistema fotovoltaico inteligente con telemetría para autosuficiencia energética del CIDIS-ESPOL

Abstract

CONDITION FOR PUBLICATION OF PROJECT. work reports the design and implementation of a photovoltaic system with energy storage and telemetry at CIDIS-ESPOL, prompted by Ecuador’s 2024 power crisis, aiming to reduce grid dependence, guarantee critical-load continuity, and optimize energy management through smart monitoring (Cerbo GX MK2, VRM/VictronConnect). The project was executed by resizing and reconfiguring the generator to a 3S3P array (nine modules) and integrating a Victron MPPT 150/45 charge controller, a Victron inverter, a 12 V gel battery bank (three units in parallel, ≈600 Ah), protections, and a wiring board; data acquisition and telemetry were implemented to log DC/AC variables and enable local and remote supervision. During tests (August 15–21), charging current reached 45 A, battery autonomy was ~3.5 h, and overall efficiency achieved 88%; the platform issued automatic alerts and kept full historical records, improving operational traceability. The estimated saving was about USD 30/month; total investment was USD 9,050.50 with NPV −USD 5,157 and IRR 0.4%, indicating limited financial profitability alone. It is concluded that the system meets its continuity and resilience goals; despite 12 V configuration constraints on financial performance, added value in operational security, sustainability, and academic use justifies the solution and enables future expansions.
