China Affordable DC Circuit Breaker Manufacturers, Suppliers, Factory

Under the action of solar energy, the photovoltaic combiner box not only improves the overall efficiency of the photovoltaic power generation system, but also our photovoltaic combiner box is equipped with advanced surge protection function.

Photovoltaic combiner box is a key device in the photovoltaic power generation system used to collect, distribute and protect the electric energy generated by photovoltaic modules.

We are honored to announce our expanding clientele in Denmark, India, Russia, and several markets across Europe and Africa. This expansion is not solely attributed to our product quality and impeccable service but also our dedication to offering cutting-edge solutions like solar photovoltaic combiner boxes, PV Switch-disconnector, solar panel connectors ,solar DC circuit breakers and DC Surge Protective Device.

This week, Wenzhou Longqi New Energy Technology Co., Ltd. (CNLonQcom) released a detailed video showcasing the production process of the LQX-C Solar DC Breaker Box. The LQX-C product is a combiner box composed of an HT2 enclosure and a 2P circuit breaker, also known as a breaker box. The video clearly demonstrates the entire production process from component assembly to the finished product, reflecting our stringent standards for product quality and production efficiency. The Solar DC Breaker Box is a crucial component of photovoltaic (PV) power generation systems. It connects individual PV strings and inverters, disconnecting the circuit in case of problems to ensure the system's safe operation.

1.Packaging Display: The video begins by showing the packaging process of the LD-40 2P 1000V Solar DC Surge Protector, ensuring that each product is well-protected during transportation. 2.Module Voltage Testing: Through rigorous voltage testing, the product is shown to function normally at voltages as high as 1300V, far exceeding the rated voltage requirement of 1000V. 3.Internal Chip Display: The video details the internal thickened chips of the surge protector, enhancing the product's durability and stability, ensuring long-term reliable operation. 4.Replacing Surge Protectors in Combiner Boxes: The video also demonstrates how to replace the surge protectors in the combiner boxes, showcasing the product's ease of maintenance and efficiency. The surge protector parameters are 1000V, 20-40KA, with CE certification, and the housing is made of PC flame-retardant material, providing excellent protection.

I. Definition and Function of PV Disconnect Switches A PV Disconnect Switch is a safety switch specifically designed for DC circuits in solar power systems. It serves two primary functions: electrical isolation and emergency shutdown, acting as the "emergency brake" of a PV system to ensure absolute safety during maintenance or faults.
