A fuse is an electrical component used for circuit protection whose core function is to automatically fuse when the current exceeds the rated value, cutting off the circuit and thereby preventing equipment damage or fire risk. The fuse is usually composed of a metal fuse (or fuse) and an insulating shell, and when the current is abnormally high, the fuse melts due to overheating and breaks the circuit.

With the continuous growth of global demand for sustainable development and clean energy, the photovoltaic industry has developed rapidly. my country's photovoltaic industry has developed rapidly and has become a leader in the global photovoltaic industry.

AC (Alternating Current) and DC (Direct Current) combiner boxes are components used in solar power systems to combine the output from multiple strings of solar panels before feeding the electrical energy into inverters.

At Wenzhou Longqi New Energy Technology Co., Ltd., we deeply understand the importance of every detail, especially in the manufacturing process of our product - photovoltaic combiner boxes. In our latest released video, viewers will have the opportunity to glimpse into how our workers focus on the assembly of combiner boxes.
