The invention relates to a photovoltaic energy storage system and a control method thereof. Wherein the energy storage battery unit is adopted as an energy storage system, and compared with a common flywheel system, the energy storage system is small in occupied area and can be conveniently applied to various different scenes; meanwhile, the main control unit is arranged, and the control mode of the energy supply control unit is correspondingly adjusted based on the working state information of the energy storage battery unit, the connected load information and the current illumination condition, so that energy storage and energy supply of the system can be reasonably scheduled, and the actual requirements are better met. 本申请涉及一种光伏储能系统及其控制方法。其中，采用储能电池单元作为储能系统，相对于通常采用的飞轮系统占地面积很小，便于在各种不同的场景中应用；同时，设置主控单元，并基于其根据储能电池单元的工作状态信息、已连接的负载信息和当前光照条件，对应调节供能控制单元的控制模式，从而可以对系统的储能和供能进行合理调度，更好地满足实际需求。
