Solar-grade fuses are devices used for overload, short-circuit, and arc fault protection in photovoltaic systems. Their main functions include protecting photovoltaic strings from conductor overload, preventing inverter backflow current from damaging solar panels, and identifying circuit faults.
In terms of technical characteristics, solar-grade fuses feature high withstand voltage, high breaking capacity, and wide temperature adaptability. Rated voltages can reach 1000VDC or 1500VDC, and rated currents range from 1A to hundreds of amperes. They are suitable for residential, commercial power plants, and large-scale photovoltaic power plants, and can adapt to the different protection requirements of centralized and distributed photovoltaic systems.
Products must comply with international and national standards such as UL248-19, IEC60269-6, and GB/T13539.6.
