Problems solved by technology

[0002] Inverter is a power adjustment device composed of semiconductor devices, which is mainly used to convert DC power into AC power. With the development of solar power generation technology, household photovoltaic inverters are more and more popular in the market. The inverter needs to be installed outdoors, and it is fixed with screws during installation. The screws are severely corroded when they are washed by rainwater for a long time, resulting in rust and death, and there is no anti-theft function
