Solar power has become the fastest growing and most widely application in the view of solar energy application. A novel stand-alone photovoltaic system topology is proposed in this paper, in which push-pull output circuit is adopted. The system consists of battery array, CUK charger, battery, boost transformation and inverter. Charging strategy based on the battery current regulation principle is adopted in CUK charger, by the way which proposed, a 100% battery state of charge is reached in shorter time. Boost topology using push-pull structure transformation. Closed-loop control method is simple and effective; it is conducive to reducing the system volume and further improves efficiency.
