Product Description:


The junction box is special design fro crystalline silicon solarmodule, adopt inner drum type crown spring contact, self-locking instruction,make electrical contact and connect more fastness, system voltage on 1000V (TUVand UL), rated current 25A and 20A. Cable length is 1meter or any other lengthfocus on customer request.

Owning to its unique compact size and design style, it is can beused for multinational solar module manufacturers on their solar panels withvarious sizes.


1). About unique design

>> Compact structure design in small thickness makes veryconvenient for transportation after assembly.

>> The main-body adopts plastic material PPE and theconnector adopts PC materials, it results not any metal material parts exposed,and lightning-proof.

2). About cable outlet

>> With the design of cable outlet on 90 degrees, it willlargely reduce the cable bending when distributing. This will result indecrease the bending stress on cable, then make it endure long lifetime.


3). About backplane adhesive force

>> Adhesive for backplane evenly distributed on box bottom,viscous force on the whole box bear evenly, it will helpful for bearing pullforce horizontal. Moreove, since more adhesive under cable outlet area, thiswill result in enhance bear more vertical pull force.

4). Floating diodes

>> Diode area float above solar module, this will be veryhelpful for heat dissipation when diodes work. What is more, it will make lessheat conduct to solar modules.
