Is there any radiation hazard in the PV system?

Photovoltaic modules and DC cables with DC current inside, no change in direction, only electricity Field, can not produce a magnetic field. Although the output transformer is AC, the frequency is very low, only 50Hz, and the generated magnetic field is very low. The inverter is A device that converts direct current into alternating current, which has a power electronic conversion, and the frequency is generally 5-20 KHz, so an alternating electric field is generated, so Electromagnetic radiation is also generated, and the state has strict standards for electromagnetic compatibility of photovoltaic inverters. Scientifically determined, the electromagnetic environment of photovoltaic power plants Below the limits of each indicator. In the industrial frequency band, the electromagnetic environment of the photovoltaic power station is even lower than that produced by the commonly used household appliances. Will not affect the health of the person.
