In the past month, our company has performed 3D modeling and application scenario videos for our isolation switches and combiner boxes. These have been posted on YouTube, and we welcome you to follow our CNLonQcom channel. Here, I freely share my technical knowledge with anyone who may find it useful. Let's now enjoy the video together.

As solar energy continues to gain popularity worldwide, the importance of safety and efficiency in photovoltaic (PV) systems cannot be overstated. One critical component that ensures both is the Photovoltaic Solar Isolator Switch (also known as a PV disconnect switch or DC isolator). This device plays a vital role in protecting technicians, maintaining system performance, and complying with electrical safety standards.

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.

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.

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.
