PV-BN128 is a solar junction box that can connect thin film photovoltaic modules to the external circuit.
PV-BN128 offers the following characteristics and benefits:
•PV-BN128 is entirely potting-glue filled, which means it contains a special adhesive that seals and protects the internal components from moisture, dust, and corrosion. This can increase the junction box’s durability and safety.
•The PV-BN128 is waterproof, outdoor-designed, and TUV-certified, which means it can survive extreme weather conditions while meeting international quality and performance standards. TUV is a German company that offers testing and certification services for a variety of products.
• PV-BN128 has outstanding high temperature resistance, fire resistance, aging resistance, and UV resistance, indicating that it can withstand high heat, flame, aging, and sunlight exposure in the outside environment. This can assure the junction box’s and photovoltaic module’s long-term stability and efficiency.
•PV-BN128 has a tiny shape, ultra-thin design, simple and practical structure, and is appropriate for 90W crystal silicon photovoltaic module or thin film photovoltaic module, which means it can fit in a small space and reduce the photovoltaic module’s weight and thickness. This can also improve the solar module’s beauty and convenience.
• The bus bar and cable connections are welded and crimped, respectively, which means that the bus bar is soldered to the junction box and the cable is pushed to the bus bar by a metal ring. This can ensure a stable and dependable electrical connection between the junction box and the solar module, as well as keep the cable from becoming loose or sliding off.
• PV-BN128 is appropriate for cadmium telluride, copper indium gallium selenium, perovskite, and amorphous thin film batteries, all of which are low-cost, high-efficiency, and flexible thin film photovoltaic cells. This means that the junction box is suitable with a wide range of thin film photovoltaic modules and applications.
• PV-BN128 is appropriate for module rear connection, which implies that the junction box is mounted to the back side of the solar module rather than the front side. Because the junction box is less exposed to sunshine and heat, it can minimize photovoltaic module power consumption and increase electrical dependability.
The PV-BN128 product procedure is as follows:
• The junction box is constructed of plastic that has been molded into a rectangular shape using a molding machine. The plastic material has good insulation and mechanical qualities, as well as the ability to withstand high temperatures and fire.
• A drilling machine drills four holes in the junction box, which are used to insert the bus bars and cables. The holes correspond to the places of the thin film photovoltaic module.
• A glue pouring machine fills the junction box with potting-glue, which covers the interior components and forms a waterproof seal. Potting-glue is an epoxy resin with high adhesive and curing qualities, as well as resistance to aging and ultraviolet radiation.
• A welding machine is used to weld the bus bars to the junction box, resulting in a robust and secure electrical connection. The bus bars are composed of copper or aluminum, both of which have high conductivity and resilience to corrosion.
• A crimping machine forms a tight and strong connection between the cables and the bus bars by pressing a metal ring around the cable and the bus bar. The cables are constructed of copper or tin, which is flexible and durable.
• A bonding machine attaches the junction box to the rear side of the thin film photovoltaic module by applying a layer of adhesive to both the junction box and the module and then pressing them together. The adhesive is a form of acrylic resin with excellent bonding and sealing capabilities as well as resistance to moisture and heat.
• A testing machine is used to verify the electrical performance, waterproof performance, temperature performance, and mechanical performance of the junction box and solar module. The testing equipment may also produce a report as well as a label for the junction box and photovoltaic module.
PV-BN128 is a product that blends high-quality materials, cutting-edge technology, and expert craftsmanship. PV-BN128 can connect thin film photovoltaic modules to the external circuit in a safe and efficient manner. It is a product you can rely on and use with confidence.
