Its main function is to serve as the dividing point between the photovoltaic power generation system and the power grid. For low-voltage grid-connected photovoltaic power stations, the photovoltaic grid-connected structure can also be equipped with metering, protection and other functional devices. When the photovoltaic grid-connected structure in the prior art is in use, the staff needs to isolate and power off the photovoltaic grid-connected inverter, and at the same time, it needs to be lifted to a certain height. For example, the Chinese utility model with application number 202220767612.3 proposes a building photovoltaic grid-connected device. During the use of the device, when the height needs to be adjusted, the lifting mechanism at the bottom of the installation box body is used to push the installation box as a whole upward to achieve height adjustment.
