Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic optimizers, in particular to a photovoltaic component optimizer. Background Art

[0002] The photovoltaic power optimizer adopts a unique software algorithm that can track the maximum power point of a single component in real time. Users can choose different types of power optimizers according to the actual operating conditions of the photovoltaic system to solve the problem of reduced power generation of the photovoltaic system caused by shadow obstruction, component orientation differences or inconsistent component attenuation, achieve the maximum power output and online monitoring of a single component, and improve system efficiency. The optimizer structure decouples the maximum power point tracking (MPPT) of the photovoltaic array into the maximum power point tracking of each photovoltaic component. While solving the problems of photovoltaic component mismatch and partial shading, it can also monitor the performance of photovoltaic components to facilitate system operation and maintenance.

[0003] A photovoltaic module power optimizer with the announcement number CN220586239U authorized by China makes it convenient to install and fix photovoltaic module power optimizers of different sizes through the structural design of the optimizer fixing mechanism, and also improves its fixing effect. The position of the movable clamping frame can be pulled by the mutual use of the telescopic rod and the spring. After the photovoltaic module power optimizer is placed, the movable clamping frame is released, and the photovoltaic module power optimizer is clamped and fixed by the elastic reset of the spring. However, this patent still has certain shortcomings when used. Although the optimizer adds a telescopic rod and a spring during installation, it is still fixed to the photovoltaic panel by a clamping fixing method, which is the same as the traditional clamping fixing method in terms of diameter, and both have the disadvantages of clamping, and both have the disadvantages of difficult to evaluate connection quality and insufficient connection strength. Therefore, we propose a photovoltaic module optimizer to improve the above problems. Utility Model Content
