[0022] like Figure 1 As shown, the single-phase photovoltaic energy storage machine inverter of the present invention includes a lower box body 1, which is open and includes a bottom plate and side plates. An inductor component 2 is connected to the side of the bottom plate near the edge, and a power board 3 is provided on the side of the inductor component 2 away from the bottom plate. A control board 4 is connected to the middle of the power board 3. The inductor component 2, the power board 3 and the control board 4 are all located inside the lower box body 1. An upper cover 8 is provided on the front end surface of the lower box body 1. The upper cover 8 and the lower box body 1 are sealed. By installing the inductor component 2 inside the inverter, there is no need to open a mold on the outside, which reduces the cost of opening the mold for the inductor shell and greatly reduces the weight of the inverter.

[0023] The outer surface of the bottom plate is tightly connected to the radiator 5, and the rear surface of the radiator 5 is provided with a back plate 6. The radiator 5 is directly and tightly connected to the lower box 1, which reduces the internal temperature of the inverter and the temperature of the components, thereby ensuring a longer service life of the components and the inverter.

When the current in the circuit surges, it can temporarily store the excess energy and release the energy when needed to ensure the stability of the current. The power board 3 is used to provide current voltage to the electronic equipment, and the control board 4 is used to manage and control the power supply. By installing the inductor component 2 inside the inverter, there is no need to open a mold on the outside, which reduces the cost of opening the mold for the inductor shell. The inductor arrangement structure of the energy storage inverter is optimized, which is conducive to reducing costs and reducing the weight of the inverter.
