Description

An automatic protection device for a photovoltaic solar device

technical field

The invention relates to an automatic protection device for a photovoltaic solar energy device.

With the vigorous development of my country's photovoltaic power generation industry, the power generation efficiency and service life of photovoltaic power generation systems are increasingly valued.

Photovoltaic solar panels are an important part of the photovoltaic power generation system. They are used to receive solar energy and convert it into electrical energy. Because they are exposed to the outside and the surrounding environment is complex, especially there are many houses and trees around distributed photovoltaics.
