Abstract: A wiring device of photovoltaic power generation equipment includes an aluminum wire and a copper-aluminum transition element. One end of the aluminum end is connected with the aluminum end of the copper-aluminum transition piece, and the other end of the aluminum end is configured to connect with an external connecting component. The copper end is configured to connect with photovoltaic power generation equipment. In the wiring device of the photovoltaic power generation equipment provided in the present application, the copper-aluminum transition piece is arranged at the position of the photovoltaic power generation equipment, and the aluminum end of the copper-aluminum transition piece is connected to the external connecting component by the aluminum wire, avoiding using copper wire for long-distance conduction. The cost of the aluminum wire is much lower than that of the copper wire. Therefore, the cost of the wiring device provided by the application is reduced.

Abstract: The present application discloses an energy storage cabinet, including a battery management module and a battery assembly. The battery management module is located on the side wall of the battery assembly, and the battery management module is electrically connected to the battery assembly. In the energy storage cabinet according to the present application, because the battery management module is located on the side wall of the battery assembly, the mounting height of the battery management module is effectively reduced, which is convenient for workers to control the battery management module, further facilitates the operation of the energy storage cabinet, and improves the safety of workers operating the energy storage cabinet.

Abstract: A stacking power supply cabinet is provided. The stacking power supply cabinet includes a top assembly and at least one battery module. In a case that the number of the battery module is more than one and the multiple battery modules are stacked sequentially from top to bottom, an electric connection path for power supply and/or storage is established among the stacked multiple battery modules, and the electric connection path is conducted via a power transmission line in the top assembly, and then the battery modules are charged. Thus, in the installation process of the power supply cabinet, the electric connection path for the power supply and/or storage among the multiple stacked battery modules is uncharged before the top assembly is installed, thereby reducing the risk of electric shock to the human body and improving the safety during the installation process of the stacking power supply cabinet.

Abstract: An inverter is provided. In the inverter, an electronic device is disposed inside a first enclosure; a heat radiator and a cooling fan are disposed inside a second enclosure; a magnetic element is disposed outside the first enclosure and the second enclosure. In this way, the cooling effect on the electronic device inside the first enclosure and the heat radiator inside the second enclosure are increased as they may be less affected by the heat generated by the magnetic element. It is also beneficial to heat dissipation of the magnetic element. The cooling fan blows the heat radiator for heat dissipation; the magnetic element does not block the relatively cold air flowing through the heat radiator. Therefore, a less obstructed air duct is formed, and the dissipation effect is improved.
