[0050] Specific implementation process:

[0051] First step: In actual use, the user can open the cover plate of the photovoltaic inverter protection box 1, then assemble the photovoltaic inverter body 7 in the photovoltaic inverter protection box 1, and install the bottom of the photovoltaic inverter body 7 with the four sets of shock absorbing assemblies 3 by using the bolt. When the photovoltaic inverter body 7 is installed, the cover plate is closed, and the photovoltaic inverter protection box 1 is closed.

[0052] Second step: When the photovoltaic inverter body 7 is installed on the four sets of shock absorbing assemblies 3, the photovoltaic inverter body 7 can press the shock absorbing block 37 and the rubber seat 36 downward by using its own weight, and at the same time, the connecting plate 35 is pressed downward.
