The solar energy storage system proposed in this study is composed of the maximum power point tracking converter, boost converter, energy storage device and switch. In order to explore the effect of different energy storage devices on improving voltage instability, the following two energy storage devices are tested and analyzed in this paper. The first one is the super-capacitor energy storage module with fast charging and discharging characteristics. Because super-capacitors generate large charging current when the initial voltage is too low, additional series current limiting resistors must be designed. The second is a hybrid energy storage module, which consists of a super-capacitor in parallel with lithium-ion batteries. The hybrid energy storage device composed of a super-capacitor and lithium-ion batteries can give full play to the advantages of a super-capacitor, such as high power density, long life, fast charging and discharging speed, and high energy density of lithium-ion batteries. Finally, the super-capacitor energy storage module and the hybrid energy storage module are used to supply power to the DC motor. According to the measurement results of the charge/discharge of these two energy storage modules, it is shown that two different energy storage devices supply power to the same motor load. Although the charging time of hybrid energy storage device is 32 seconds longer than that of the super-capacitor energy storage module, it is 50 seconds longer than that of the super-capacitor energy storage module, which indicates that hybrid energy storage device can maintain the normal power supply of load side for longer than super-capacitor energy storage module.
