The standard designation PV1-F 1×4mm² is the most commonly used photovoltaic (PV) DC cable on the DC side of photovoltaic power generation systems, where "4" refers to the nominal cross-sectional area of the conductor being 4mm². It is specifically designed for DC high-voltage transmission between solar modules, between modules and combiner boxes, and between combiner boxes and inverters. It features excellent resistance to UV radiation, weathering, high and low temperatures, flame retardancy, and halogen-free low smoke properties, making it the standard DC connection cable for distributed PV, residential PV, and building-integrated photovoltaics (BIPV) projects.
