Full potting 1500V good quality split junction box PV-BN3H1A
Description
1,This solar junction box adopts full Potting-glue, waterproof, and has been certified by TUV. This product is a high-heat dissipation and high-power junction box developed for 166,182,210, heterojunction and other crystal silicon high-efficiency half cell PV module.The copper bridge and diode are welded by DC resistance spot welder,which can make the copper bridge and diode pins fuse together,and the contact resistance is almost zero,reducing the power loss of the PV module.The diode pin falls off from the copper bridge without the influence of high temperature caused by welding strip.Compared with the modular junction box on the market,this product can increase the passing current by about 10%under the same conditions of diode chip,and the junction temperature is lower.
2,This product uses more mature and stable technology R6 package high-power Schottky diode,diode pin is 1.3mm and 2.0mm (according to the power and current size of the PV module).
3,Mini design:this junction box is suitable for back connection of solar module,small and compact,with clean adhesive path on the back plate and less adhesive ,which is conducive to the transportation of customer PV module after installation.

Solution
● PV module’s ribbon alignment must be complied with JB’s mounting hole of the terminal base.
● Adhesive and sealing compound, Potting glue must be applied by using specific type and specification. Make sure JB will be fixed in the correct position and reliable sealant. The potting glue level should be over the top surface of Diodes and terminal base. In order to avoid electrical shock risk.
● Don’t move PV module or JB before adhesive and sealing compound or potting glue solidify.
● Ensure soldering between Ribbons and terminal reliably in order to avoid missing soldering or false soldering. The soldering operators must be professionally trained. More soldering time will cause the diodes damaged.
● Adopt anti-static protection solutions when touch or solder JB.
● Make sure the connection method between JB and PV module in the correct polarity. Otherwise, Wrong connection will cause fire.
● PV module manufacturer should inspect the diodes of JBs before shipment since the diodes might be damaged by heat temperature or the static shock.
● Installation or maintenance should be operated by the professional personnel.
● For protection against electric shock, while being assembled or disassembled, make sure connectors isolated from the power supply.
● Don’t connected or disconnected under load.
● During the assembly process, keep the connector away from any corrosive materials.
