The difference between photovoltaic combiner box and inverter

    The photovoltaic combiner box is a key component that concentrates the direct current energy of multiple photovoltaic modules and converts it into alternating current energy. It is often installed in photovoltaic power plants, playing a role in collecting, protecting, and distributing the direct current energy generated by photovoltaic modules. The photovoltaic combiner box can also monitor the working status of photovoltaic modules, helping managers to promptly identify faults and carry out maintenance.
    Inverters and combiner boxes are closely related in photovoltaic power plants. The battery panels used in photovoltaic power plants are usually composed of multiple batteries, with each panel having a power range of 10-300W. Therefore, in order to ensure the maximum overall efficiency of solar energy collected by photovoltaic panels, it is necessary to connect several panels together with certain voltage and current requirements to form a relatively strong array of panels. At this point, a combiner box is required to converge the current and voltage of different directions and discrete battery panels, which are then processed by the inverter to achieve effective energy output.
    Therefore, photovoltaic combiner boxes and inverters are not the same. The photovoltaic combiner box is responsible for collecting, protecting, and distributing DC energy, while the inverter is responsible for converting DC energy into AC energy for supply to the power grid. For those who build and use photovoltaic power generation systems, it is very important to understand the differences and functions between photovoltaic combiner boxes and inverters, which will help to better understand the working principle and performance of photovoltaic power generation systems.
