Torre professional home photovoltaic unit, thunderstorm days, solar
overvoltage protection device.
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.
Company profile
