Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a photovoltaic power generation energy storage device. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. This technology is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, and then combined with power controllers and other components to form photovoltaic power generation devices. The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When sunlight shines on the PN junction, the current flows from the P-type side to the N-type side, forming a current.

The body is connected with a handle, a photovoltaic power generation device, a driving lifting device, a mobile structure and a ventilation and dehumidification device. The driving lifting device is connected with a rotating adjustment device. When in use, the photovoltaic panel generates electricity through sunlight, and the electricity enters the battery for storage through the wires and the inverter. The first electric telescopic rod pushes the push plate and the card plate to rise to adjust the height of the photovoltaic panel. The first motor drives the driving rotating rod, the sliding rod and the card plate to rotate to adjust the direction of the photovoltaic panel. When the device needs to be moved, the second electric telescopic rod is extended to make the roller contact the ground to lift the device. The handle can be pushed to move the device.
