[0003] The main function of the photovoltaic combiner box is to monitor the photovoltaic series and peripheral auxiliary components. At present, the photovoltaic combiner box is mainly divided into two types: one is the non-intelligent photovoltaic combiner box, and the non-intelligent photovoltaic combiner box can only be used for parallel wide current. functions, it is impossible to monitor the operating status of the internal modules of the photovoltaic combiner box, its safety and reliability are poor, and its intelligence is low, which cannot meet the production needs; the other is the intelligent photovoltaic combiner box, which is more intelligent than the non-intelligent type High product, strong safety and reliability
[0004] However, the existing intelligent photovoltaic combiner boxes can only monitor the total current after parallel connection, and cannot monitor the current and voltage of a single battery array. The protection function is relatively single and the degree of intelligence is low.

The invention discloses a novel intelligent photovoltaic confluence device. The novel intelligent photovoltaic confluence device comprises a box body and a confluence circuit arranged in the box body, wherein the confluence circuit is used for converging a plurality of paths of photovoltaic direct current into one path; and the confluence circuit comprises a plurality of paths of anode input connectors for inputting anode direct current, a plurality of paths of cathode input connectors for inputting cathode direct current, and a detection module for detecting current size and voltage size of each path of input photovoltaic direct current. The novel intelligent photovoltaic confluence device disclosed by the invention is provided with the detection module so that single battery array voltage and battery array current can also be detected except converged total voltage and total current, and the intelligent degree is higher.
Description
technical field [0001] This application relates to the technical field of photovoltaic power generation applications, in particular to a new type of intelligent photovoltaic confluence device. Background technique [0002] At present, the problem of energy shortage is becoming more and more serious. Clean energy is the inevitable development direction of today's low-carbon and environmentally friendly life. Solar energy is the main energy source in the future. , in order to reduce the connection between the solar photovoltaic cell array and the inverter, simplify the system structure, and improve the reliability and maintainability of the power generation system, a certain number of output cables of the photovoltaic cell square array with the same specification can be connected in series. Several photovoltaic series are formed, and then several photovoltaic series are connected in parallel to the photovoltaic combiner box, and after converging in the photovoltaic combiner bo...
