[0002] With the continuous updating of photovoltaic-related technologies, the application of photovoltaic power generation is becoming more and more extensive. Inverters, as an indispensable part of photovoltaic power generation, can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency.

Due to the large size of inverters and their installation outside, existing inverter mounting brackets simply cover the inverter by connecting the bracket and the canopy. This bracket installation method exposes more of the inverter, thereby increasing the risk of environmental interference. The heat dissipation window of the existing inverter bracket exposes the inverter body to the outer wall through holes.
