PRODUCT OVERVIEW
The secondary photovoltaic DC surge protector is a device specifically designed to protect the DC photovoltaic power inside the combiner box of a solar photovoltaic system. Its main function is to prevent equipment damage or malfunction caused by surges or electromagnetic interference in photovoltaic systems.
This type of protector usually follows relevant testing standards, such as EN 5053911 and GB/18802-31 as you mentioned. These standards specify the technical requirements and performance indicators that protectors must meet to ensure that they can effectively protect photovoltaic systems from the effects of surges and surges.
Main characteristics
1. Complete pre wiring base: This means that the protector is equipped with a pre wiring base, making it easier to install in the photovoltaic system. This design takes into account the special wiring method of the photovoltaic system, providing convenience for installation.
2. Y-shaped connection method: Adopting a Y-shaped connection method can avoid damage to the lightning arrester caused by insulation failure in the generator circuit. This connection method may improve the stability and reliability of the system, reducing potential risks caused by insulation faults.
3. Special anti DC arc device: This feature aims to avoid accidents caused by arcs. DC arc may cause serious safety issues in photovoltaic systems, so special devices are used to prevent the occurrence of arc, thereby improving the safety of the system.
