DC Surge protective device (Solar Photovoltaic)
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.
