PV DC Combiner Box TDXLD-4/1 6/1 12/1

Technical Data

Product Introduction

The PV DC Combiner Box is the core connecting equipment in photovoltaic grid connected power generation systems, designed for efficient aggregation and safe protection of DC power output from photovoltaic modules. With excellent performance and reliable configuration, it builds a key defense line for the stable operation of photovoltaic systems. ​

In terms of protection performance, the product has reached IP65 protection level, with strong dust and water resistance, and can easily cope with complex outdoor environments such as rainy and dusty conditions. Whether installed outdoors on rooftops or photovoltaic power plant sites, it can effectively isolate external water vapor and impurities from entering, ensuring long-term stable operation of internal components and greatly reducing equipment damage caused by harsh outdoor environments. ​

In terms of voltage adaptability, the combiner box supports dual voltage specifications of 1000V/1500V, which can flexibly match photovoltaic modules and system design requirements of different power levels. It can adapt to the 1000V system of small and medium-sized photovoltaic projects, as well as meet the 1500V system requirements of large ground photovoltaic power stations for high voltage and high power. It has strong compatibility and provides convenient equipment selection for photovoltaic projects of different scales. ​

The security protection configuration can be considered comprehensive, with multiple core security components integrated into the equipment. Firstly, it has a built-in DC Fuse (direct current fuse), which can quickly fuse and cut off the faulty circuit in case of overload, short circuit or other abnormal situations, avoiding the expansion of the fault and protecting the safety of photovoltaic modules and subsequent equipment; Secondly, equipped with DC SPD (direct current surge protector), it can effectively absorb transient surge overvoltage generated by lightning or circuits, prevent surge impact from damaging sensitive components, and enhance the system's anti-interference ability; Thirdly, equipped with DC Circuit Breaker/DC MCCB (DC Circuit Breaker/DC Molded Case Circuit Breaker), it can achieve normal on/off control and fault protection of the circuit, with both manual operation convenience and automatic tripping protection function, providing dual protection for the safe operation and maintenance of DC circuits. ​

In terms of material selection, the product adopts an all metal shell, which not only has excellent structural strength, but also has excellent impact resistance and corrosion resistance. It can resist the aging problems caused by long-term outdoor sun and rain exposure, extend the service life of the equipment, and the metal material can also assist in heat dissipation, avoiding the impact of high temperature on the performance of internal components, further improving the stability and reliability of equipment operation.
