Description

Technical Field

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

[0002] A photovoltaic energy storage cabinet is an organic combination of an energy storage cabinet and a photovoltaic system. Photovoltaic power generation mainly uses photovoltaic panels. Under photosynthesis, the photovoltaic panels convert light energy into electrical energy and store the electrical energy inside a storage battery connected to the photovoltaic panels, facilitating the conversion and utilization of light energy.

[0003] The existing photovoltaic panels are installed on the top of the energy storage cabinet, and multiple storage batteries are placed inside the energy storage cabinet. However, due to the limited internal space of the energy storage cabinet, when taking the storage battery, the operator's hand will be blocked by the energy storage cabinet, making it impossible to stably hold the storage battery. For storage batteries of different models, their sizes also vary, and there is no device for stably limiting the position of the storage battery inside the energy storage cabinet. When the energy storage cabinet is subjected to external impacts or other forces, the storage battery will move inside the energy storage cabinet, affecting the stable energy storage requirements of the storage battery. In addition, the cables used for connecting the storage battery and the photovoltaic panels are generally placed randomly inside the energy storage cabinet. Over time, the cables become entangled, affecting the stable connection between the storage battery and the photovoltaic panels, and it is also inconvenient to repair the cables later.
