目前，多数光伏系统只有一套蓄电设备，并将充电控制器直接由光伏电池供电，一旦蓄电池能量放完后因系统无替代电源便无法工作；光伏电池输出的电压受光照的影响也就直接导致控制电路工作不稳定。该文针对这种情况设计出两套包含蓄电池的子系统的替换方案，并对方案的实现创新了电压检测、电子开关的实现办法。通过实测后，系统达到了预期效果，方案可行。

Currently,many photovoltaic systems have only one storage device,and their charge controllers are directly powered by the photovoltaic cells. Once the battery releasing energy,the system will not work because of having no substitution source. The output voltage of the photovoltaic cells is influenced by the illumination. This will also directly lead the control circuit unstable. In this paper,the design of two sets of the replacement scheme for the subsystems of the battery was introduced. In order to achieve the program,the method of power supply detection and electronic switch has been innovated. Through the actual measurement,the system will a-chieve the desired results,so this design is feasible.
