What is a Maximum Power Point Tracker? The Maximum Power Point Tracker (MPPT) optimizes the amount of power obtained from the photovoltaic array used to charge the electrical power supply Why Design a MPPT? Our design is customized to meet the varying conditions of solar car racing, i. e. shadows, over-sun exposure, weather conditions, etc.
