Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a photovoltaic bypass diode module unit. Background Art

[0002] Photovoltaic bypass diode module unit, also known as photovoltaic bypass diode, is a special-purpose diode, which is often used in photovoltaic power generation systems. Its main function is to provide a current path to bypass the photovoltaic cells on the photovoltaic panels when the lighting conditions are not ideal or the photovoltaic cells fail to function, so as to protect the entire system from damage. The working principle of photovoltaic bypass diode is similar to that of ordinary bypass diode. When the photovoltaic panels generate voltage, under normal circumstances, the current passes through the photovoltaic cells into the load or energy storage device to complete energy conversion and storage. However, when the light intensity is insufficient, the photovoltaic cells fail or the positive and negative electrodes of some panels are short-circuited, the voltage will rise on the photovoltaic cells, which may cause damage to other components. At this time, the photovoltaic bypass diode will automatically turn on and bypass the photovoltaic cells with current exceeding the photovoltaic cell voltage to ensure the safe operation of the system.

[0003] However, when the existing photovoltaic bypass diode module unit is in use, when the outdoor light intensity is high, the high temperature environment outside can easily cause damage to the bypass diode, and the bypass diode has insufficient protection effect outdoors, so it is easily damaged, thereby reducing its service life.
