PV DC combiner box
Product Products
Photovoltaic dc junction box
Product Name:

Photovoltaic dc junction box

Listing Date: 2016-03-10

 

Main features:


1)The cabinet made of hot dip galvanized steel features safe and liable structure with sufficient mechanical strength to guarantee no shaking or deformation of the components after installation during the operation;

 

2)Protection grade reaches IP65, waterproof, dust-proof, anti-rust, and salt spray resistance characteristics, as well as the outdoor installation can be satisfied;

 

3) Simultaneously access to the battery serials up to 18 channels;


4) Anode and cathode per battery serial are protected by special photovoltaic fuses. Fuse base supported by the fuse wire will reduce post-stage maintenance cost for the owner, and effectively protect the personal safety of maintenance staff; the fuses and fuse wire conform to TUV certification;


5) DC output bus is equipped with PV-specific lightning device. Surge protection shall be provided among anode-ground, cathode-ground and anode-cathode, and lightning proof products shall be certified by TUV;


6) The combiner box is equipped with module-based smart detection unit to detect the current, output voltage, box temperature, along with the status of lightning proof device and circuit breaker per serial module;


7) Current measurement will be subject to Hall sensor perforation measurement; measurement equipment is completely isolated from electrical equipment so that normal system power generation would not be affected even if the measurement unit fails, which effectively improves power generation efficiency and equipment safety;


8) Digital display from intelligent detection unit could display such information as current, voltage, power, temperature, device address & number, etc on the body; it should be simple and convenient to set detection unit address so that device address could be easily changed without auxiliary equipment;


9) Smart detection unit of module-based combiner box features the machine power less than 4W, and measurement accuracy up to 0.5%;


10) It features Multi-way remote data transmission with RS485 interface & wireless ZigBee interface, in conjunction with built-in lightning protection function in communication interface, effectively protect communication port;


11) Smart detection unit of module-based combiner box is subject to DC 1000V self-powered mode; power supply in this mode will be packed in modular plastic form. Power supply functions reverse connection protection, over-current & overvoltage protection, anti-corrosion, and dust resistance, etc;


12) Device body is labeled with such information as Aluminum nameplate, marking technical parameter, item name & number.


13) One of first batch of the companies passing Golden Sun certification for PV combiner box.
