  • 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.

  • Looking Ahead: New Trends and Challenges in the Photovoltaic Industry

    Against this backdrop, our range of products, including PV switch-disconnectors, combiner boxes, circuit breakers, surge protectors, and solar connectors, emerges as key solutions. Our PV switch-disconnectors and combiner boxes not only enhance system safety and efficiency but also reduce installation and maintenance costs through innovative design. Our circuit breakers and surge protectors provide outstanding system protection, preventing electrical failures and damage, while our solar connectors offer unmatched connection reliability, ensuring long-term stable operation of the system.

  • Brazil's Serra da Babilônia Wind-Solar-Storage Hybrid Project: Stabilizing the "Debut" of Clean Energy

    On the land of northeastern Brazil, an energy project named Serra da Babilônia officially "commenced operations" in December. As the first wind-solar hybrid project in Brazil by Norwegian energy company Equinor, it serves as a "model example" for the development of clean energy in the region. Some friends may wonder: what exactly is wind-solar-storage hybrid energy? And what can this project—comprising 1.1GW of photovoltaic (PV) capacity and a 100MW/200MWh energy storage system—bring to Brazil? Today, we'll explain the ins and outs of this new energy project in the simplest terms.
