  • Wenzhou Longqi New Energy Technology Co., Ltd. Emphasizes the Crucial Role of DC Combiner Boxes in Solar Photovoltaic Systems

    As a crucial component of solar PV systems, the DC combiner box is responsible for collecting the output currents from multiple solar panels, consolidating them, and then uniformly transmitting them to the inverter. This not only simplifies the wiring but also significantly reduces the maintenance complexity and costs of the system. Additionally, these combiner boxes are equipped with circuit breakers and surge protection functions, further enhancing the safety of the system. In the event of a failure or the need for maintenance, the combiner box can quickly disconnect the connection between the solar panels and the rest of the system, protecting maintenance personnel from electric shock.
