Aiming at the low energy efficiency of the photovoltaic charging system, this paper presents the hardware and software design of an improved PV charging system. The system based on low-power micro-controller MSP430F1611 uses perturbation and observation method and controls the digital potentiometer to regulate the output voltage of the MPPT converter. Thus the energy storage devices could obtain the maximum power when the ratio of PV cells power and MPPT converter efficiency is optimal. After simulation, we achieve the desired results, and the energy storage devices could get more power under the same conditions.
