solar module junction box

lower resistance and voltage drop, fewer-lossing output power, better heat releasing and corrosion resistance, longer service life Product Summarization PV-RK801-1solarmodule junction box is perfectly designed especially for solar modue with large heat-releasing room, high rated current and low-loss power and so on. It provides users with a rapid, safe and reliable connection solution. The products' performance indexes surpass the like products' at home and abroad, and win the national structure invention patent and utility model patent. Main Technical Specification Rated Voltage: 1000V Rated Current:25A Ambient Temperature: -40°C +85°C Protection Class: Class II Protecton Degree: IP67 Rated Connecting Capacity: 4-6mm2 Product Features (Series PVRK80 & PVRK90) A The shall of Series 90 aluminum alloy junction box has been designed as standard blade to cooling, molding together with the plastic inner; B Better heat dissipation performance, and higher protection degree; C To meet the hard outdoor condition, and longer service life; D Patented integration of inserted terminal design; E With lower resistance and voltage drop, fewer-lossing output power. Integrated junction box connector (Series PVRK80 & PVRK90 ) Patent No.: 200910305097.6 201020203781.1 I. The integrated connector of the junction box has been adopted their own materials to double back and form the two circular grooves which could close contact with the cylindrical diode pin. That's another important invention and breakthrough in PV junction box field. II. Better meeting the diode's pins, closer integration, more extensive contact surface, these minimize the contact resistance, and the product voltage drop and degree of output power lossing could be lower. III. With full-fit mechanical retaining mechanism, its service life is much longer than the one with point-like linear connection and welded connection. IV. The integrated connector system as a unity, is a stereo conductive transmission system with the diodes' pins plug into the holes to be together as one piece, so the performance of the transmitted power is greater. V. The integrated junction box connectors mold as the one, instead of three or more, which has saved more non-ferrous metals.
