The special surge protector for photovoltaic system, under normal circumstances, the surge protector is in a high resistance state, and the leakage current is extremely low, so as to ensure the normal power generation of the photovoltaic system.

When the system is activated, the JLSP series photovoltaic system surge protector will be turned on immediately within nanoseconds, limiting the voltage amplitude within the safe and normal range of the equipment. At the same time, after the surge energy is absorbed, the surge protector will quickly It becomes a high-resistance state, so as not to affect the normal operation of the photovoltaic system.

With the rise of photovoltaic grid-connected power generation in various places, the photovoltaic power generation system is constantly optimized in practice, and the power generation efficiency is also continuously improved. At the same time, the system voltage level also presents a variety of different power generation systems, and the surge protectors that need to be installed are also endless. same. In centralized photovoltaic power generation, the DC side surge protector is mainly used in the DC combiner box, DC power distribution and AC measurement, and can be installed between the inverter and the power distribution panel, between the power distribution panel and the AC load, and in the box transformer. on the AC line between the low voltage side.

For the string photovoltaic power generation system, the protector is mainly used at the AC test of the inverter and the AC combiner box, and on the AC line between the AC combiner box and the low-voltage side of the box transformer to protect the line. For the distributed photovoltaic power generation system developed in recent years, the DC side surge protector can be installed in the photovoltaic controller to protect the equipment, and the AC surge protector is mainly installed in the low-voltage side of the box transformer for protection.
