In specific implementation, in this embodiment, the energy storage inverter assembly 8 can adopt the inverter assembly used for photovoltaic energy storage scheduling in the prior art.

[0028] At the same time, if Figure 4 As shown, a card slot 9 is provided on the bottom side of the machine box 1, and a docking slot 11 is provided on the bottom side of the machine cover 2 corresponding to the position of the card slot 9.
