Product Description

Efficient Confluence Function
1.Precise Current Pooling:Korlen combiner box precisely gathers photovoltaic branch currents, ensuring that many branch currents are accurately summarized to the main circuit in large power plants, avoiding current disturbances affecting the system.
2.Low Loss Confluence:The use of advanced circuit design and high-quality materials, low power loss during the confluence, can improve the photovoltaic system power generation efficiency, compared with the ordinary confluence box can save energy for a long time.

 

Reliable Electrical Protection
1.Overcurrent Protection: Sensitive overcurrent protection device, when the current exceeds the safe value, quickly cut off the circuit, protect the equipment from sudden short circuit or branch fault caused by overcurrent damage.

2.Overvoltage Protection: Effective overvoltage protection mechanism to cope with the abnormal voltage rise caused by light and power grid fluctuations, protect the internal circuit and equipment, and extend the service life.
 

Rugged Housing
1.Superb Material Manufacturing: The shell is made of high-strength metal alloy or corrosion-resistant engineering plastic, which is resistant to pressure and impact, and can protect the internal components in harsh environments (such as high winds and hail areas).

2.High Sealing: High sealing, prevent dust, moisture into the desert or coastal areas to ensure the internal electrical environment is stable.

 

Reasonable Internal Layout
1.Compact Design: The internal layout is compact, saving space, small size, easy to transport and install, and the component connection line is simple, easy to maintain and repair.

2.Easy Wiring: The design is convenient for wiring, reduces installation time and difficulty, reduces electromagnetic interference, and ensures the stability of the electrical system.

 

Suitable for a Variety of Photovoltaic Systems
1.Component Compatibility
Compatible with monocrystalline silicon, polysilicon, thin film and other types of photovoltaic modules, there is no need to configure a separate bus box in the mixed component power station, reducing construction costs.

2.Equipment Compatibility: Compatible with inverter, monitoring system and other equipment, can be seamlessly connected to the photovoltaic system, accurate transmission of current data to the monitoring system for operation and maintenance.

Install Automation
1.Simple Installation: Simple installation, no complex tools and professionals, clear installation interface and line connection description, bolt and plug connection, shorten installation time.

2.Flexible Installation Position: The installation position can be flexibly selected as required, and it can work normally in the photovoltaic array bracket or the power distribution room, adapting to different site conditions.

 

Ease of Maintenance
1.Convenient Access to Repair: The internal structure is easy to repair, the component layout is layered or modular, and it is easy to contact the components for troubleshooting and replacement.

2.Visual Monitoring and Maintenance Tips: Some of the bus boxes have visual monitoring and maintenance prompt function, through the display screen or indicator to display operating parameters, failure prompt, reduce downtime.
