COMPARATIVE ANALYSIS OF MPPT AND PWM SOLAR CHARGED CONTROLLER FOR BATTERY CHARGING SYSTEM
Abstract
The project aimed to conduct a comprehensive comparative analysis between two types of solar charge controllers, Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM), to determine their effectiveness in charging batteries within a solar power system. The project successfully accomplished these objectives by setting up a solar power system with separate MPPT and PWM charge controllers, conducting comprehensive texts, and taking measurement of basic electrical parameters of the charging system. Parameters measured are Voltage and the charging current. The measurements were carried on MPPT and PWM charge controller under the same condition using digital multimeter. The comparative analysis revealed several significant findings, MPPT controllers exhibited faster charging times and tended to better preserve battery life by optimizing charging parameters, whereas PWM controllers, though simpler, showed slower charging rates. For higher efficiency applications, where solar conditions vary widely, MPPT controllers might be more suitable. Conversely, for simpler systems with predictable conditions, PWM controllers could suffice.
