Solar alternating-current energy storage power supply device and control method thereof

Abstract

The invention relates to a solar alternating-current energy storage power supply device and a control method thereof. The device comprises a casing; the casing comprises an upper casing and a lower casing, wherein a battery pack is arranged in the lower casing; a control circuit is arranged in the upper casing; the control circuit comprises a main control unit, a power charging unit, a detecting unit, an inverter, a charging control unit, a solar charging board and a solar charging unit; the upper casing and the lower casing are connected through a detachable structure; the power charging unitinputs the power of the power source and detects an input signal of the power source; the solar charging unit is used for inputting electric energy of the solar energy and detecting an input signal of the solar energy; the charging control unit receives the signal of the main control unit, switches on or off the power supply to the battery pack; and the main control unit drives the battery pack to output the electric energy to the inverter according to a detection signal, wherein the electric energy is transmitted to a load via the inverter. The solar alternating-current energy storage powersupply device and the control method thereof in the invention realize the detachable connection of the battery box body and the inverter box body, facilitate the replacement of the battery and the inverter, facilitates the maintenance of the battery and the inverter, and achieves strong practicability.

Description

technical field [0001] The invention relates to a solar energy storage power supply device, more specifically to a solar AC energy storage power supply device and a control method thereof. Background technique [0002] Energy storage mainly refers to the storage of electric energy. At present, in order to protect the environment and save energy, everyone advocates converting natural energy such as solar energy and wind energy into usable electric energy to provide power for people. [0003] The solar energy is converted into electrical energy, specifically, the solar energy is irradiated on the solar panel for energy conversion, and then the converted energy is charged to the battery to achieve the effect of energy storage, and the battery can be used for charging mobile phones or lighting. At present, most solar energy storage devices are connected with the battery box and the inverter 7 box in a fixed connection mode. Once the battery life ends, the entire box can only be ...

AI Technical Summary

Problems solved by technology

At present, most solar energy storage devices are connected with the battery box and the inverter 7 box in a fixed connection mode. Once the battery life ends, the entire box can only be disassembled for replacement or maintenance. Batteries cannot easily replace electrical appliances. Similarly, when the inverter 7 is damaged and needs to be replaced, it is also quite difficult, and the maintenance cost is too high
