China Affordable Molded Case Circuit Breaker Online Manufacturers, Suppliers, Factory

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.

The waterproof terminal at the bottom of the combiner box is loose, causing the cable to loosen, resulting in arcing and burning the terminal‌.

The system's working principle is as follows: • Energy Collection: Solar panels capture sunlight and convert it into DC. • Energy Integration and Conversion: DC current is centralized through the combiner box and converted into AC by the inverter. • Safety Assurance: Isolator switches, circuit breakers, and surge protectors guarantee operational safety and system stability. • Energy Storage and Management: The battery protection box ensures safe battery charging and discharging for effective energy management.
