Surge protectors play an important protective role in PV combiner boxes. PV combiner boxes are a key component in PV power generation systems.

This week,CNLonQcom officially launched on Alibaba, marking a significant step in our global market expansion. Through the Alibaba platform, we aim to connect with more international customers and provide high-quality photovoltaic products and solutions.

AC (Alternating Current) and DC (Direct Current) combiner boxes are components used in solar power systems to combine the output from multiple strings of solar panels before feeding the electrical energy into inverters.

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 offers DC surge protectors in various specifications to meet the needs of different systems and voltage levels. For typical home or RV solar systems with voltages ranging between 500V to 1000V, choosing a 500V or 1000V DC surge protector suffices. For industrial applications, where system voltage may reach up to 1500V, selecting a 1500V specification surge protector is necessary to provide adequate protection.

The lightning protection system combines basic components such as air terminals, appropriate down conductors, equipotential bonding of all current carrying components, and appropriate grounding principles to provide a roof that prevents direct impact.
