Product Details
Photovoltaic DC surge protector is a lightning protection product designed for the solar photovoltaic system based on the relevant standards. The photovoltaic lightning protection device is used to protect the sensitive line of the solar power generation protection device. It can maximize the voltage into the underground, protect the inductive thunder and direct lightning or other instantaneous overvoltage, so as to achieve the effect of lightning protection.
Use of attention
1. in order to limit the inductive coupling between the protected part after installation and the part of the unprotected equipment, we need to make some measurements. The mutual inductance can be reduced by the separation of the inductive source and the sacrificial circuit, the selection of the loop angle and the limitation of the closed loop area.
2. when the current carrying conductor is part of the closed loop, the circuit and the induced voltage decrease as the conductor approaches the circuit.
3. the protected conductors should be separated from the wires which are not protected, and they should be separated from the ground wires. At the same time, in order to avoid transient orthogonal coupling between power cables and communication cables, necessary measurements should be made.
Product features
1. access multi-channel solar array at the same time. The maximum current per channel can reach 11A, which can meet different user needs.
2. use temperature control protection circuit, built-in thermal protection
3. equipped with high voltage DC fuse and circuit breaker, two level safety protection device.
4. thunderbolt counting function, it is easy to understand the invasion situation and frequency of lightning disasters.

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.
