Solar junction boxes are devices that connect the solar cells in a photovoltaic module and provide a safe and reliable electrical connection to the external circuit. Solar junction boxes are essential components for the performance and efficiency of photovoltaic modules. PV-BN221 is a high quality and hot sale 1500V thin film junction box that Zhejiang Boneng developed to meet the market demand. PV-BN221 has the following features:
• PV-BN221 is fully potting-glue, waterproof, outdoor design and certified by TUV, which means it meets the international standards of safety and quality.
• PV-BN221 has excellent performance of high temperature resistance, fire resistance, aging resistance and ultraviolet resistance, which can meet the long-term use under outdoor harsh environmental conditions.
• PV-BN221 has a small shape, ultra-thin design, simple and practical structure, and suitable for 90W crystal silicon photovoltaic module or thin film photovoltaic module, such as cadmium telluride, copper indium gallium selenium, perovskite, amorphous thin film batteries.
• PV-BN221 has a reliable electrical performance, as the connection of the bus bar and the cable is welded and crimp respectively, which ensures a stable and low-resistance contact.
• PV-BN221 is suitable for the module back connection process, which can reduce the power consumption of photovoltaic modules and improve electrical reliability, as the JB mounting hole of the terminal base must line up with the ribbon of the PV module.
Product Installation and Maintenance
PV-BN221 is easy to install and maintain, but it requires some precautions and instructions to ensure its proper functioning and safety. Here are some tips to follow:
• Compound for sealing and adhering: Applying potting glue requires a precise kind and specification. Make certain JB will be fixed in the appropriate location with a trustworthy sealant. Diodes and the terminal base’s top surface should be covered in potting glue to reduce the risk of electrical shock.
• Avoid moving the PV module or JB until the potting glue, adhesive, and sealing compound have fully hardened.
• To prevent missing or erroneous soldering, make sure the connection between the Ribbons and terminal is reliably soldered. The soldering operators need to have formal training. The diodes will become damaged with more soldering time.
• Use anti-static protection techniques when handling or soldering JB.
• Ensure that the PV module and JB are connected using the proper polarity. If not, the incorrect connection will start a fire.
• Before shipping, the diodes of JBs should be examined by the PV module manufacturer because they may be harmed by heat or static shock.
• Professional specialists should do any installation or maintenance.
• Make sure connectors are disconnected from the power source while being assembled or disassembled to prevent electric shock.
• Under a load, avoid connecting or disconnecting.
• Keep corrosive materials away from the connector while it is being assembled.
