solar PV DC Combiner Box String Box Junction Enclosure

Short Description:

In the solar photovoltaic power generation system, in order to reduce the connection between the solar PV array and the inverter, improve the reliability of the system, and facilitate the installation and maintenance of the system, it is generally necessary to add a combiner box between the PV module and the inverter.

The PV combiner box is suitable for photovoltaic grid-connected and off-grid power generation systems. Its main function is to converge the input of PV array.
It’s with two protection measures:
1st: The PV combiner box is configured with PV dedicated high-voltage lightning arrester, DC fuse and circuit breaker to provide short circuit fault protection and lightning protection.
2nd: It has monitoring module inside so as to monitor the current & voltage and then locate string fault alarm for quick problem solving.

PV Combiner Box provides a means of combining multiple source circuits from a PV array into a single DC output. Each source circuit is fused separately using a touch-safe fuse holder. The combiner box allows for fail-safe operation of the system in the unlikely event that a problem with a source circuit leads to abnormally high current. In addition, the combiner box provides a convenient means of accessing the DC portion of a PV system for routine maintenance and troubleshooting.
In the solar photovoltaic power generation system, in order to reduce the connection between the solar PV array and the inverter, improve the reliability of the system, and facilitate the installation and maintenance of the system, it is generally necessary to add a combiner box between the PV module and the inverter.
Series Combiner Boxes can accommodate up to 36 input circuits at 600 VDC, 1000 VDC, or 1500 VDC. Each channel is with
a fuse. The output side Is equipped with lightning protection and a circuit breaker. It greatly simplifies the input wiring of the
DC power distribution cabinet and Inverter. Realize lightning protection, short circuit protection, and grounding protection.
PV combiner box divided Into two types： intelligent box and non-lntelligent box. The Intelligent PV combiner box Is equipped with
a monitoring unit, then detect Input current of each string, detect Inside temperature, detect lightning protection status, detect
circuit breaker status and summarize output voltage, and so on.
The product adopts outdoor wall-mounted type, which adapts to the harsh environment. In addition to the core components, the other
can be customized by user requirements.
