Abstract

The invention relates to a solar power supply device and a control method, the device comprises a solar cell panel which is used for receiving solar energy and converting the solar energy to electric energy, a super-capacitor module which is connected with the solar cell panel and is used for storing electric energy, a cell storage module which is connected with the super-capacitor module and is used for electric energy, a general control module which is separately connected with the super-capacitor module and the cell storage module and is used for controlling the super-capacitor module and the cell storage module to switch between charging and discharging states, and a direct current convertor unit which is separately connected with the general control module and a load and is used for switching the states of direct current output; the method comprises the steps: a super capacitor bank supplies power for the load when the voltage is greater than the start threshold voltage, charges a cell pack when the voltage is greater than the start voltage, and charges and controls the cell pack to charge the load when the voltage is lower than the lowest threshold voltage. Compared with the prior art, the method provided by the invention has advantages of high power generating efficiency, long service life, good versatility, high use value and the like.

Description

technical field [0001] The invention relates to the field of distributed photovoltaic power generation, in particular to a solar power supply device and a control method. Background technique [0002] Wireless sensing and remote monitoring technology is one of the important means to ensure social production. Due to geographical and practical conditions, most wireless sensing and remote monitoring nodes cannot obtain mains power. It is an ideal measure to use solar power generation technology for its power supply. However, due to the limitation of power generation efficiency and the service life of energy storage batteries, it is difficult to realize long-term monitoring of solar power. How to improve the power generation efficiency of solar power and prolong the service life of the system has become a priority issue for solar power. [0003] Patent CN2636433Y provides a solar power controller device, which detects the state of the solar battery pack and the storage batter...
