Photovoltaic Fuse: Safety bodyguard for Photovoltaic System

  With the increasing global attention to renewable energy, photovoltaic technology has gradually become a shining star in the energy field. In photovoltaic system, the importance of photovoltaic fuse cannot be ignored that it can be acted as critical safety protection component. This article will take you to gain a deeper understanding of the definition, function, working principle, usage scenarios, and selection points of photovoltaic fuse, and jointly explore its importance in photovoltaic system.

 Definition and function of photovoltaic fuse:

Photovoltaic fuse is a kind of current protection device specifically designed for photovoltaic system. This kind of fuse is mainly used in   circuit cut-off in case of the abnormal current, in order to prevent equipment damage and the fire accidents. Compared with traditional fuses, photovoltaic fuse can carry higher current and possess longer service life. When the current in the photovoltaic system exceeds the rated value, the metal link inside the photovoltaic fuse will heat up and reach the melting point. And then, it will fuse and cause open circuit, protecting equipment and personal safety.

The working principle of photovoltaic fuse

The working principle of photovoltaic fuses is based on the thermal effect during current overload. The thermal effect can response swiftly.

Photovoltaic fuse is widely used in various scenarios. In household photovoltaic systems, photovoltaic fuse is usually installed between the battery panel and inverter to protect the home circuit from the impact of reverse current and current from short circuit inside the battery panel. In industrial photovoltaic systems, photovoltaic fuse is usually installed between the battery panel and the junction box to protect the junction box and the entire photovoltaic circuit. For large photovoltaic power plant, due to the large number of battery panels, the selection and use of fuses are particularly essential. Except installation between the battery pack and the combiner box, the fuse is also be installed between the combiner box and the inverter to achieve multi-level protection

In short, photovoltaic fuse, as important protection component in photovoltaic system, plays an important role in protecting equipment and personal safety. By understanding the information of photovoltaic fuse, we can professionally choose and employ it, providing strong guarantee for the safe and stable operation of photovoltaic system. In the future development, with the continuous progress of photovoltaic technology and the continuous expansion of application fields, photovoltaic fuse will come into play in wider fields.
