The photovoltaic terminal box comprises a power optimization device, the power optimization device comprises an intelligent detection module, a maximum power point acquisition module, a current regulating module and a control module, wherein the control module is connected with the intelligent detection module, the control component is further respectively connected with the maximum power point acquisition module and the current regulating module, the control component is used for controlling the maximum power point acquisition module and the current regulating module to work. The photovoltaic terminal box disclosed by the invention has the beneficial effects that the output power of the photovoltaic generation system is maximized so as to guarantee that the energy source utilization rate of the photovoltaic generation system is high.

Description

technical field

[0001] The invention relates to the field of photovoltaic power generation, in particular to a photovoltaic junction box for maximizing power generation. Background technique

[0002] Solar cell modules are generally made of several cells arranged in series and laminated and pressed with encapsulating materials. The terminal is connected with a waterproof junction box and connected to a cable and a plug. boards connected in series.

[0003] However, the traditional photovoltaic junction box is passively receiving solar energy and outputting electric energy through the connection of the junction box. Due to the momentary change of the light intensity, the output power of the entire photovoltaic junction box is also changing from time to time. Furthermore, due to the It consists of several solar panels. In the actual operation of solar panels, the output current of the solar panels often drops sharply due to various shadows or other factors. Since the panels a...
