PV DC Combiner Box TDXLD-16/1

Technical Data

Product Introduction

As the core convergence and protection equipment in photovoltaic grid connected systems, the PV DC Combiner Box is designed specifically for DC photovoltaic systems, with high reliability, strong protection, and comprehensive safety assurance capabilities. It can efficiently achieve current collection, fault protection, and status monitoring of multiple photovoltaic modules, providing key support for the stable operation of photovoltaic power plants. ​

1、 Excellent protection, adaptable to complex environments

The product adopts a Metal shell design, which not only has a sturdy and durable structure, but also can withstand long-term impact, corrosion, and aging in outdoor environments. It also reaches IP65 protection level - completely dust-proof and can withstand violent water spray. It can be directly installed on roofs, outdoor brackets, and other outdoor scenes, easily coping with harsh weather conditions such as rain, snow, sand, and high temperature, greatly reducing the impact of environmental factors on equipment. ​

2、 Multiple security protections to ensure system stability

To ensure the safety of DC circuits, the product integrates multiple core protection components:
DC Fuse: Accurate overcurrent protection. When the circuit experiences overload or short circuit, it can quickly cut off the faulty circuit, avoiding damage to components or backend equipment and reducing the risk of fire; ​
DC SPD (direct current surge protector): effectively suppresses transient overvoltage caused by lightning strikes, grid fluctuations, etc., prevents surge currents from impacting key equipment such as photovoltaic inverters and controllers, and enhances the system's anti-interference ability; ​
DC MCCB (direct current molded case circuit breaker): With manual disconnection, overload protection, and short circuit protection functions, it is easy to operate and has strong disconnection ability. It can be used as the main switch or branch protection switch of the circuit, making it convenient for system maintenance and fault diagnosis. ​

3、 Wide voltage adaptation, compatible with various scenarios

The product supports a wide DC voltage range of 1000V/1500V, which can match both conventional 1000V photovoltaic systems and efficient 1500V high-voltage systems. It is compatible with photovoltaic modules and inverters of different power levels, meeting the needs of various application scenarios such as distributed photovoltaic power stations and large-scale ground photovoltaic power stations, and providing higher flexibility for system design. ​

4、 Intelligent monitoring, real-time monitoring of operating status

Built in Monitoring module, which can real-time collect key data such as current, voltage, temperature, etc. inside the combiner box, and upload it to the photovoltaic monitoring system through a communication interface (such as RS485). Operation and maintenance personnel can remotely check the operating status of equipment, timely detect issues such as overcurrent, overheating, and communication failures, reduce on-site inspection workload, and improve the efficiency and management accuracy of power station operation and maintenance. ​

The PV DC Combiner Box, with its advantages of high protection, full protection, wide adaptability, and intelligent monitoring, has become an indispensable key equipment in photovoltaic DC systems, providing protection for the safe, efficient, and stable operation of photovoltaic power plants.
