Abstract

This paper presents a preliminary experimental study on the use of an analog bidirectional current sensor
for photovoltaic (PV) systems operated under Maximum Power Point Tracking (MPPT) control. The ultimate goal
of this research is to develop a comprehensive monitoring system for energy harvesting from PV systems using a
PLC-based platform. As an initial step, this study investigates the behavior of a bidirectional sensor in detecting
charging and discharging processes in an off-grid PV configuration. The sensor is evaluated through experimental
measurements of current and voltage outputs, where the bidirectional characteristic provides an indication of the
direction of energy flow—charging when energy is stored in the battery and discharging when energy is supplied to
the load. Data acquisition and visualization are performed using LabVIEW, which allows real-time monitoring and
validation of sensor performance at specific time intervals. The experimental results provide insights into the
accuracy and reliability of the analog bidirectional sensor under varying operating conditions. The novelty of this
study lies in its focus on sensor behavior analysis as a foundation for future PLC-based monitoring system
development. By validating sensor performance through this pre-study, the research ensures that reliable data can
be obtained for subsequent integration into a real-time monitoring and control system for PV energy harvesting
applications
