Usually, the low-voltage DC generated by photovoltaic power generation is converted into AC power and then output. The cables connecting the photovoltaic components and the AC / DC inverters are the photovoltaic power station cables. Therefore, photovoltaic power station cables, as the backbone of power transmission of photovoltaic power generation facilities, are directly related to the safety, reliability and advancement of solar photovoltaic power generation systems.
