The photovoltaic combiner box is an important component in the photovoltaic power generation system. Its function is to gather the direct current generated by the photovoltaic modules and provide it to the inverter, and then the inverter converts the direct current into alternating current for use by users.
The protection level of the photovoltaic combiner box refers to the protection ability of the photovoltaic combiner box against the external environment. The protection level of the photovoltaic combiner box consists of two numbers. The first number indicates the protection ability of the photovoltaic combiner box against solid objects, and the second number indicates the protection ability of the photovoltaic combiner box against water.
IP67 is the highest protection level for photovoltaic combiner boxes, which means that photovoltaic combiner boxes can be dustproof and waterproof, and can be immersed in water to a depth of 1 meter for 30 minutes without being affected.
The impact resistance level of the photovoltaic combiner box refers to the ability of the photovoltaic combiner box to withstand external impacts. The impact resistance level of the photovoltaic combiner box is represented by the IK value. The higher the IK value, the stronger the impact resistance of the photovoltaic combiner box.
IK10 is the highest impact resistance level of photovoltaic combiner boxes, which means that photovoltaic combiner boxes can withstand 10 joules of impact energy without damage.
The corrosion resistance level of photovoltaic combiner boxes refers to the resistance of photovoltaic combiner boxes to external corrosion. The corrosion resistance level of the photovoltaic combiner box is represented by C5, which is the highest corrosion resistance level of the photovoltaic combiner box, which means that the photovoltaic combiner box can resist salt spray corrosion.
The IP67 protection level, IK10 impact resistance level, and corrosion resistance level C5 of the photovoltaic combiner box make it very suitable for applications in harsh environments. The photovoltaic combiner box can be installed outdoors without being disturbed by wind, rain, sunlight, dust, salt spray and other external environments, and can work stably for a long time.
