Smart connecting box and photovoltaic power generation system applying same

Abstract

The invention provides a smart connecting box. The smart connecting box is characterized in that a smart component is mounted in the smart connecting box and comprises a detecting module, a CPU (central processing unit) module and a transmission module, wherein the detecting module is used for detecting work state information of a single solar panel, an output end of the detecting module is connected with an input end of the CPU module, and an output end of the CPU module is connected with the transmission module. By the smart component, running state of each solar panel can be detected, troubleshooting time is shortened, efficiency is improved, and daily maintenance and overhauling are facilitated.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to an intelligent junction box and a photovoltaic power generation system using the intelligent junction box. Background technique [0002] With the promotion of energy conservation and emission reduction, renewable energy has been more and more widely used. Among the renewable energy sources, solar energy has attracted the attention of the people because of its cleanliness and ease of access. Therefore, solar power plants have emerged as the times require. The solar power station consists of battery panel components connected in series and parallel to form a photovoltaic array. Through the junction box, the electric energy generated by the battery panel components under the action of photovoltaics is imported into the inverter or controller, and the inverter or controller converts the solar energy into the inverter or controller. The form of electric energy is converte...

Problems solved by technology

[0003] However, due to the large number of solar panel components, when a certain solar panel fails, a string of solar panel components connected in series cannot work, seriously affecting the power generation efficiency of the solar power station; and the user has no way of knowing the cause of the failure. occur

Even if the user finds that the power generation cannot meet the expected target and indirectly knows that the battery panel component is faulty, the location of the faulty battery component cannot be determined. A large number of investigations must be carried out during maintenance, and the workload is very huge, especially for building integrated photovoltaics. In chemical power stations, the battery panel components are generally installed on the top of the building, making it more difficult to overhaul
