Solar energy generator arrester prevents high voltage surge, photovoltaic current limiting switch circuit breaker.
Product Details
Photovoltaic DC surge protector is a lightning protection product designed for the solar photovoltaic system based on the relevant standards. It is an electronic device that provides safety protection for solar photovoltaic devices. When the peak current or voltage is suddenly produced in the electrical circuit or communication line because of the external interference, the surge protector can guide the shunt in very short time, thus avoiding the damage of the surge to other equipment in the circuit. The lightning protector uses the multilevel protection circuit, selects the brand components and uses the advanced production technology. It has the characteristics of large flow capacity, low residual pressure level, sensitive reaction, stable performance, reliable work and so on.
Product features
1. equipped with high voltage DC fuse and circuit breaker, two level safety protection device.

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.
Use of attention
1. connect the positive and negative pole and the ground wire to the positive and negative poles and the earth terminals of the lightning protector respectively, and screw the terminals. Connect the grounding wire and the lightning protection system reliably. When the wiring is completed, check the wiring is correct and firm, then switch on the power supply and put it into operation. Before installing the lightning protection module, we must cut off the power supply, and no live operation is strictly prohibited.
2. it is recommended to fuse fuse or automatic circuit breaker at the front end of DC power supply lightning protection module.
3. this product does not need special maintenance at ordinary times. It only needs to check regularly whether the connection is loose and whether the working state is normal.
