Photovoltaic surge protectors are mainly used in the following scenarios in photovoltaic systems:

1. Surge protection: Mainly used in low-voltage power supply systems of power generation companies and power consumption companies. It is installed in low-voltage incoming cabinets, power supply cabinets, distribution cabinets, distribution boxes, etc., to protect electrical equipment from lightning strikes and operations. Damage caused by overvoltage intrusion.

2. Suitable for various DC power supply systems, such as photovoltaic power generation systems, background broadcast systems, communication systems, industrial control systems, etc.

Foreign researchers Smit and Ricks believe that a direct lightning strike may cause an increase in ground potential, causing surge protection equipment to behave erratically. In addition, the same direct lightning strike will induce currents in the DC wiring loop throughout the PV plant, causing fast transients to propagate through the DC wiring. Current research on surge protection devices and photovoltaic power plants is limited and often implements a simple grounding system representation in their models, neglecting the effects of ground potential rise and induced currents. Other research attempts have focused on the study of induced currents, completely ignoring the possibility of ground potential rising. Current research also ignores factors that may affect the protective capabilities of surge protection devices. Ultimately, a modeling technique more suitable for photovoltaic power plants is needed to perform fast transient analyses, such as modeling the effects of lightning strikes on photovoltaic power plant equipment.

Jinli is a company integrating R&D, production and sales. Since its establishment in 2006, it has 18 years of experience in producing surge protectors. The DC series photovoltaic surge protectors we currently develop and produce are developed based on different modeling types. We can provide the most suitable model according to your usage and parameter requirements. For ordinary home users, choosing a suitable and cost-effective surge protector can meet their basic needs; while for special industries such as large industrial enterprises, it may be necessary to choose higher specifications and more reliability based on actual conditions. Photovoltaic surge protector to ensure the safety and normal operation of equipment.
