Surge protection device to prevent lightning surge voltage in low-voltage electrical system or solar energy system (photovoltaic power supply system). These devices must be installed in parallel on the low-voltage distribution system or DC power supply system to be protected, and provide common and different modes of protection. Its installation location is recommended to be located at the front end of the household side of the distribution system or at both ends of the DC power line (solar panel side and inverter/converter side), and equipped with matching circuit breakers or fuses
