A professional home solar photovoltaic protector protection circuit system.

Brief introduction

Photovoltaic DC surge protector is a lightning protection product designed for the solar photovoltaic system based on the relevant standards. It is suitable for the power supply systems, such as TT, TN-S, TN-C, IT, and other power supply systems, such as TT, TN-S, TN-C, IT, and other power and control systems of the factory. It protects the indirect lightning and direct lightning and other transient overvoltage surge, which is mainly applicable to residential, third industry and industrial and mining enterprises.

Product specification

Working principle of product

In the solar photovoltaic system, the inductive or capacitive coupling voltage is caused by the lightning shock and the switching operation of the upstream power supply system. Therefore, the surge may damage the photovoltaic modules and inverters, which will cause serious consequences for the operation of the photovoltaic system. The photovoltaic lightning arrester is specially developed for this purpose. The lightning protection module of the DC power supply, once the high voltage, and endanger the insulation of the protected equipment, the lightning arrester acts immediately, and the high voltage impact current is directed to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so as to protect the power equipment.

Company profile

Thor has been designing new products to meet the RoHS directive since 2006. Thor’s ongoing commitment to RoHS compliance includes continuing efforts to reduce the presence of hazardous substances in the design and manufacture of a growing number of popular products.

All types and classes of our lightning and surge arresters 20KA~200KA(8/20μS) and 15KA~50KA(10/350μS) are tested and pass all the requirements based on their class.
