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.

CNLonQcom's circuit breakers, overvoltage and undervoltage protectors, surge protectors and fuses are all made of high-performance fire-retardant PA66 material, which can self-extinguish during the combustion process and significantly reduce the spread of fire.

A solar circuit breaker switch is a specialized electrical device designed to protect solar power systems from overloads, short circuits, and other electrical faults.

As the global energy transition accelerates, the synergistic effects between photovoltaics (PV) and new energy vehicles (NEVs)—two major green industries—are becoming increasingly evident. From solar rooftops on vehicles to integrated solar-storage-charging stations, companies across the supply chain are rapidly exploring innovative applications of "PV + NEVs." Industry experts predict that this cross-sector collaboration will create a market worth over 100 billion yuan by 2030.

In low-voltage power distribution systems, there is a key device quietly safeguarding circuit safety — the Molded Case Circuit Breaker (MCCB). Unlike large motors that operate with a roar or precision instruments that attract attention, the MCCB has become an indispensable "safety guardian" in scenarios such as industrial production, building electrical systems, and new energy applications, thanks to its strong protection capabilities and wide adaptability. Today, we will explore this device from multiple dimensions to uncover the secrets of how it protects circuit safety.

On March 26, 2025, the 1GW (gigawatt) Xiangcheng Gongzha Photovoltaic Project in Ganzi Tibetan Autonomous Prefecture officially broke ground. As the largest single PV project invested by a Sichuan provincial state-owned enterprise, it not only marks a key milestone in the local new energy sector but also reflects the distinct trend of China’s national solar industry accelerating toward large-scale, intelligent, and high-efficiency development.
