Product FAQ
What is the main purpose of PV Combiner Box-Din-Rail Type?
PV Combiner Box-Din-Rail Type is mainly used in photovoltaic power generation systems to bring together the output of multiple photovoltaic modules and provide necessary protection functions such as overcurrent protection and lightning protection. It is an important part of the system.
What is the internal structure of PV Combiner Box-Din-Rail Type?
It is mainly composed of DC circuit breaker, lightning arrester, fuse holder, terminal block and shell. Some models can also be equipped with intelligent monitoring unit to monitor the current, voltage and other parameters of each line in real time.
What should be paid attention to when installing PV Combiner Box-Din-Rail Type?
During installation, it is necessary to ensure that the polarity of each connecting cable is correct and waterproof sealing is done. The installation location should avoid direct sunlight and rain, and facilitate subsequent maintenance.
What are the cable introduction methods?
Cables can be introduced through holes at the bottom or side of the box, and waterproof connectors or glands can be provided. Cable troughs, junction boxes and other accessories can also be selected to achieve flexible wiring.
How is the heat dissipation method?
Reasonably design ventilation and heat dissipation holes, and optional forced heat dissipation devices such as fans can be used. High-end products may also have built-in temperature control devices to intelligently adjust the temperature inside the box.
