As a result, multiple screw installations are required when installing the battery module and the energy storage inverter, leading to complex operation and low efficiency during installation. Summary of the Invention

[0005] To improve the connection efficiency between the fixed base, battery module and energy storage inverter, this application provides a household energy storage power device and its usage method.

The multiple battery modules are electrically connected to the energy storage inverter. The device also includes a positioning and connecting mechanism for connecting the fixed base, battery modules, and energy storage inverter.

[0007] By adopting the above technical solution, when using the energy storage power device, multiple battery modules need to be installed on the fixed base first, and then the energy storage inverter is installed on the battery modules. By electrically connecting with multiple battery modules, the power supply in the battery modules can be realized. The connection and fixation between the fixed base, battery modules and energy storage inverter are realized through the positioning and connection mechanism, making the installation of battery modules and energy storage inverter more stable, simple and convenient, and highly efficient.

[0008] Optionally, the connection mechanism includes a positioning component and a connection component; the positioning component is disposed between the fixed base and the battery module, two adjacent battery modules, the energy storage inverter and the battery module, to keep the fixed base, the battery module and the energy storage inverter on the same vertical axis; the connection component is disposed on the fixed base, and the battery module and the energy storage inverter are detachably connected to the fixed base through the connection component.

[0009] By adopting the above technical solution, the positioning component keeps the fixed base, battery module and energy storage inverter on the same vertical axis, and then the connecting component connects the fixed base, battery module and energy storage inverter, thereby improving the stability of the energy storage power device.

[0010] Optionally, the positioning assembly includes four sets of positioning rods, which are vertically positioned at the four bottom corners of the battery module and the energy storage inverter. The fixed base and the four top corners of the battery module are each provided with insertion holes that are compatible with the positioning rods.

[0011] By adopting the above technical solution, when installing the battery module, the positioning rod at the bottom of the lowest battery module is inserted into the insertion hole on the fixed base, and then the battery modules are installed in sequence, with the positioning rod at the bottom of the battery module inserted into the insertion hole on the lower battery module. When installing the energy storage inverter, the positioning rod at the bottom of the energy storage inverter is inserted into the insertion hole on the lower battery module, thereby keeping the fixed base, battery module and energy storage inverter on the same axis. The structure is simple and the installation is convenient.

[0012] Optionally, the connecting assembly includes a fixing plate, which is fixedly connected to one side of the fixing base in a vertical direction.
