Embodiment Construction

[0020] In order to make the objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] figure 1 It is a structural block diagram of a solar energy storage power generation system 100 in an embodiment. The solar energy storage power generation system 100 includes a solar switch 110 , a solar controller 120 , an energy storage module 130 , a mains input switch 140 , a charger 150 and a sine wave inverter 160 . The energy storage module 130 includes a battery management system and a lithium iron phosphate battery. The lithium iron phosphate battery is used instead of the traditional lead-acid battery, which has a long life, small weight, and less pollution to the environment. The solar switch 110 is connected to the solar controller 120, the solar controller 120 is connected to the energy storage module 130, the energy st...

Abstract

The invention relates to a solar energy storage power generation system which comprises a solar controller, an energy storage module, a mains input switch, a charger and a sine wave inverter. The solar controller is used for performing constant voltage charge on a lithium iron phosphate battery in the energy storage module; the energy storage module is connected with the solar controller and comprises a battery management system and the lithium iron phosphate battery, and the battery management system is used for protecting the lithium iron phosphate battery and detecting and displaying state information of the lithium iron phosphate battery; the mains input switch is arranged between a mains state grid and the charger and between the mains state grid and the sine wave inverter; the charger is connected with the energy storage module and used for switching mains into electric energy for the lithium iron phosphate battery; and the sine wave inverter is used for inputting mains into electric loads directly when the mains is input into the sine wave inverter, and when the mains is disconnected, the sine wave inverter jumps automatically to inert the electric energy stored in the lithium iron phosphate battery into sine wave alternating currents to be output to the electric loads. According to the solar energy storage power generation system, electrical appliances can work normally during a sudden power failure and the reliability is high.

Description

technical field [0001] The invention relates to an electric energy storage system, in particular to a solar energy storage power generation system. Background technique [0002] At present, household solar energy storage power supply cabinets usually use lead-acid batteries to store excess power generated by photovoltaics to ensure stable power supply for loads. However, lead-acid batteries have disadvantages such as great environmental pollution, heavy weight, and short service life, so they must be eliminated. When home users lose power or in areas where power transmission is underdeveloped, household solar energy storage power supply cabinets are more practical and do not need to be connected to the national grid. use. [0003] However, the traditional solar power supply system still has some room for improvement. For example, it does not have a backup power supply function, and cannot guarantee the normal use of electrical appliances when sufficient solar energy cannot...
