MC4 photovoltaic connector is a very familiar component for most industry practitioners. Because of its existence, whether it is in the link of photovoltaic power plants, or the very critical parts of the core combiner box and inverter, it becomes very simple.
His existence is inevitable, because the photovoltaic system has been operating in extreme temperature changes of extreme heat and extreme cold for a long time. Because it is required that the MC4 connector must be able to maintain stable working performance in such a harsh environment. Colleagues must not only be resistant to high temperature and moisture and water, but also have safety protection on touch and high current-carrying capacity when current passes. In addition to the above requirements, low contact resistance is also a relatively important consideration.
MC is the abbreviation of Multi-Contact, and 4 is the size standard of the metal core diameter. The combination of the two of them is our commonly used MC4 photovoltaic linker, and its appearance in 2002 has completely realized the real plug and play. With the continuous updating of technology, the development of the entire MC4 series has been very mature and can meet the needs of users at different levels.
