PV AC Combiner Box TDHL for Solar Power Systems

Technical Data

Product Introduction

In the photovoltaic grid connected power generation system, the PV DC combiner box is the core intermediate equipment that connects the photovoltaic modules and inverters, and plays a key role in convergence, protection, and monitoring. It can effectively reduce the number of connection lines between the photovoltaic modules and inverters, improve the overall operating efficiency and safety of the system, and is an essential equipment for large-scale ground photovoltaic power stations, industrial and commercial distributed photovoltaic projects, and rooftop photovoltaic systems. ​

Core configuration and advantages

High level protection, suitable for complex environment: The product protection level reaches IP65, with excellent performance of complete dust prevention and water spray prevention, and can easily cope with outdoor rainstorm, sand dust, high temperature, humidity and other adverse weather conditions. Whether installed on the roof, outdoor power stations or industrial areas, it can ensure the stable operation of internal electrical components, significantly reduce the loss of equipment in outdoor environment, and extend the service life. ​

Multiple electrical protections ensure system safety: Equipped with a built-in DC SPD (direct current surge protector), it can quickly absorb surge currents generated by lightning or grid fluctuations, avoiding damage to core equipment such as photovoltaic modules and inverters caused by high voltage shocks, and providing reliable overvoltage protection for the system; Simultaneously configure DC Fuse and DC Isolator Switch/DC MCB, where the DC fuse can quickly melt and cut off the faulty circuit in case of overload or short circuit faults in the circuit, while the DC isolator switch/MCB supports manual circuit disconnection for easy daily maintenance and repair. The dual protection mechanism eliminates safety hazards such as electrical fires and equipment burnout from the root. ​

Wide voltage adaptation, compatible with diverse requirements: The product supports a wide DC voltage range of 600V/1000V and can adapt to different power specifications of photovoltaic modules (such as conventional 60 or 72 modules) and inverters. Whether it is a low-voltage low-power distributed system or a high-voltage high-power ground power station, it can be flexibly matched, reducing equipment selection limitations and improving project compatibility and scalability. ​

Metal material shell, sturdy and durable: The shell is made of high-quality metal material, which not only has excellent impact resistance and corrosion resistance, but also can resist physical wear and chemical erosion during long-term outdoor use. It also has good heat dissipation performance, which can quickly dissipate the heat generated during equipment operation, avoid internal components aging due to high temperature, ensure long-term stable operation of the equipment, and reduce maintenance costs in the later stage. ​

This photovoltaic DC combiner box, with its core advantages of high protection, strong safety, wide adaptability, and high durability, can provide efficient and reliable combiner solutions for various photovoltaic power generation systems, helping to improve the power generation efficiency and operational safety of photovoltaic systems. It is an ideal choice for photovoltaic project construction. ​
