Portable solar power supply system

Abstract

The invention provides a portable solar power supply system, which comprises a solar panel, a charging control module, a storage module and an inverter connected in sequence, wherein the solar panel is used for converting light energy into first direct current; the first direct current is converted into second direct current after flowing through the charging control module; the charging control module is used for outputting second direct current for charging the storage module; the storage module is used for outputting third direct current to the inverter; and the inverter is used for converting the third direct current into first alternating current for outputting. Due to the adoption of the portable solar power supply system, the power utilization requirements of various loads can be met; and meanwhile, a DC / DC (Direct Current to Direct Current) boosting module and a DC / AC (Direct Current to Alternating Current) inversion module in the portable solar power supply system are controlled respectively by using different control modules, so that the information feedback degree of the entire system is increased, the reliability of a circuit of the entire system is enhanced, and separate debugging and maintenance of the DC / DC boosting module and the DC / AC inversion module are facilitated.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a portable solar power supply system. Background technique [0002] The current portable solar power system mainly adopts two structural forms to supply power to the load. One of them is: the solar panel converts the light energy into direct current and directly charges the battery, and then converts the electric energy of the battery into one or several kinds of direct current through circuit control. However, the power supply for most loads is 220V / 50Hz AC. Therefore, this structural form cannot meet the power supply requirements for various loads of users. [0003] The other is: the solar panel converts light energy into direct current and then directly outputs it to the inverter. The inverter uses a DC / DC boost module to convert the low-voltage direct current output by the solar energy into high-voltage direct current. The DC / AC inverter module converts high-voltage direct ...
