Problems solved by technology

[0003] However, the traditional photovoltaic junction boxes are passively receiving solar energy and outputting electric energy through the connection of the junction box. Due to the momentary changes in 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 are connected in series, this will inevitably lead to the overall string of battery components. The current drops, resulting in a much lower output power of the whole string of battery components

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...
