The lithium iron phosphate battery module 8 and the power frequency inverter 17 are respectively electrically connected to the photovoltaic controller 16.

[0019] Specifically, a flat lock 20 is installed on the cabinet door 2, and it is locked and connected to the cabinet 1 through the flat lock 20.

[0020] In this implementation, the main function of the flat lock 20 is to improve the security of the cabinet 1 and prevent unauthorized personnel from accessing the equipment in the cabinet.

[0021] Specifically, a first limiting groove 21 is provided at the upper part of the first aluminum extrusion heat sink 7, and the lithium iron phosphate battery module 8 is placed in the first limiting groove 21.
