At the same time, the energy storage power supply of the present application does not need to be installed with a cabinet (only the inverter module 100 and the battery module 200 are stacked and installed). Compared with the prior art, the overall volume is smaller, the installation area is smaller, the cost is lower, and the battery module 200 is not wrapped with a cabinet on the outside, and is directly in contact with the air, which is more conducive to the heat dissipation of the battery module 200.

[0042] Further, in the embodiments of the present application, Figure 1 As shown, the energy storage power supply also includes a control module 300 (the control module 300 has display function, switch function and communication function, etc.); the inverter module 100, the control module 300 and the battery module 200 are stacked in sequence from top to bottom, and the battery module 200 and the inverter module 100 are connected and fixed through the control module 300 to realize electrical connection and control functions.

[0043] Specifically, Figure 2 As shown, the control module 300 includes an electrical component and a control housing 310, and the electrical component is arranged inside the control housing 310. The wires led out from the inverter 101 are electrically connected to the electrical component via the inside of the inverter housing 110 and the inside of the control housing 310 in sequence; the wires led out from the electrical component are electrically connected to the interface of the battery module 200 via the inside of the control housing 310.

[0044] It should be noted that the wires of the inverter module 100, the control module 300, and the wires connected to the battery module 200 of the energy storage power supply of the present application are arranged inside the inverter housing 110 and inside the control housing 310, and the wires are fixed with waterproof connectors to prevent water and dust from entering.

In this way, the number of battery modules 200 can be adjusted according to demand, which facilitates the expansion of the battery module 200. During the specific connection, the wires led out from the electrical components are electrically connected to the terminal female socket 602 of the control module 300, and the terminal female socket 602 of the control module 300 is electrically connected to the terminal male socket 601 of the first battery module 200. In this embodiment, the terminal female socket 602 is provided with a sealing ring, and the terminals are inside the module after stacking, which can effectively perform waterproof, dustproof, and electrical protection.

A surrounding frame 202 is provided on the bottom side of each battery module 200, and the surrounding frame 202 surrounds the terminal female seat 602 and is installed in conjunction with the mounting eaves.

Similarly, multiple battery modules 200 and the first battery module 200 and the control module 300 are fixed in the same way.

[0052] In addition, it is worth mentioning that in the embodiment of the present application, the energy storage power supply can be compatible with inverters 101 of different specifications and models. That is, the inverter module 100 of the present application includes multiple inverters 101 of different sizes; multiple inverters 101 of different sizes can be connected to the inside of the inverter housing 110 replaceably.

[0053] Specifically, the inverter housing 110 includes a housing body 103 and a front door 102, and the front door 102 is hinged to the housing body 103 to be engaged with or separated from the housing body 103. Figure 7 As shown, the front door 102 is hinged to the top of the housing body 103, and the front door 102 can be flipped around an axis, and the axis is perpendicular to the stacking direction.

Figure 7 As shown in the left figure of FIG. 1 , the inverter 101 can be detachably connected to the housing body 103 through the mounting ears 106 of the two crossbeams 104. Figure 7 As shown in the right figure, the inverter 101 can be detachably connected to the housing body 103 through the mounting ears 106 of the two vertical beams 105.
