    This study aimed to experimentally evaluate the energy performance of PWM and MPPT charge controllers used in an off-grid photovoltaic system. The study considered a fixed configuration and a single-axis solar tracking configuration. It used a quantitative approach and a comparative field experiment under real operating conditions. The photovoltaic system belongs to project DIRGI-CP2021-008 of Technical University of Cotopaxi. Data were collected through Modbus communication and Node-RED, and the information was processed in Microsoft Excel, electrical variables were measured at input and output of charge controllers, including voltage, current, and power transferred to the battery bank, these measurements were taken from 6:00 a.m. to 6:00 p.m. in different experimental cases. The results showed that the MPPT charge controller performed better because it operated close to the maximum power point and properly controlled battery charging stages. In contrast, the PWM charge controller depended on battery voltage and controlled the energy through pulses. It was concluded that MPPT technology makes better use of solar energy and provides more efficient energy management, especially when it is combined with single-axis solar tracking.
