Intelligent solar conjunction box

Abstract

The invention relates to an intelligent solar conjunction box in the field of solar technology. The conjunction box comprises a conjunction box body and a conjunction box cover match covers the conjunction box body in pair, an accommodation cavity is formed between the conjunction box body and the conjunction box cover, and internally provided with a master control circuit board, the front end of the master control circuit board is welded to four binding posts, a first terminal and a second terminal are respectively welded at the two sides of the rear end of the master control circuit board, the master control circuit board comprises a master control chip, a thermosensitive sensor, a voltage sensor and a current sensor, and the master control chip is mounted between a first joint and a second joint. The master control circuit board is additionally arranged to monitor the temperature, voltage and current of a solar cell panel in real time; and thus, defects and hidden safety hazard in a system can be found in shortest time, faults can be rapidly eliminated, power of the solar cell panel in different complex climate environments can be output in an optimized manner, the total photovoltaic power generation efficiency of the solar cell panel is improved, and the power generation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to an intelligent solar junction box. Background technique [0002] Solar energy is an inexhaustible clean energy, and the use of solar panels to generate electricity has become popular. As a very important component on the solar panel, the solar junction box has achieved certain innovation and optimization under the efforts of countless technicians. [0003] As we all know, the junction box on the traditional solar panel only has the function of connecting the panel and transmitting current. However, in the long use of the solar photovoltaic system, it is often encountered such as chimneys, tree shade, bird droppings, dark clouds, dust, etc. Factors greatly reduce power generation efficiency and increase fire hazards. International authoritative solar photovoltaic experts have shown that in severe cases, when 10% of the power generation area of ​​the photovoltaic system is blo...

[0003] As we all know, the junction box on the traditional solar panel only has the function of connecting the panel and transmitting current. However, in the long use of the solar photovoltaic system, it is often encountered such as chimneys, tree shade, bird droppings, dark clouds, dust, etc. Factors greatly reduce power generation efficiency and increase fire hazards. International authoritative solar photovoltaic experts have shown that in severe cases, when 10% of the power generation area of ​​the photovoltaic system is blocked, the maximum power loss may be as high as 60% of the entire system. At the same time, even if there are no special factors, under normal use conditions, the solar power station will cause a total power loss of 9%-11.5% due to various comprehensive factors, which is not only a major safety hazard for the photovoltaic system, but also causes The power generation efficiency of photovoltaic system is greatly reduced
