Question: Is a specific tool needed to install TE’s Solar IPC P2S 240?Īnswer: No, the installation of our P2S 240 can be done using a spanner 13 mm A/F. The P2S 240 will help you achieve high-quality electrical contact by piercing the double insulation layers without affecting the mechanical performances of the flexible solar conductors at the tap side. The P2S 240 meets the specific solar requirements regarding protection and insulation performance (degree of protection IP68, voltage test underwater at 6.5 kV for 5 min, impulse withstand test) and specific raw material features (glow wire test at 650☌, flame retardant property HB according to UL94). Question: Why is TE’s Solar IPC P2S 240 different from the other IPCs already available?Īnswer: Our solar IPC P2S 240 has been specially designed to connect PV cables up to 1.5 kV DC using double insulated stranded (class 2) aluminum cables for the bus cable and double insulated flexible (class 5) copper cables for the jumper cables. Over-molded fused harness eliminates the need for combiner boxes.Reduce installation time allows more flexible farm design.Length of jumper wires reduced up to 50% with reduced voltage losses thanks to bigger sections (cost reduction). The Trunk Bus system is designed to reduce material and labor costs during installation, and ultimately improves the efficiency of the DC grid system: The strings are protected using an over-molded fused harness. With the trunk bus system, each panel string is connected to a Bus cable (70-240 mm²) thanks to our Insulation Piercing Connector (P2S 240). Question: What is the difference between the solar farms using a conventional method or the trunk bus system?Īnswer: With a conventional system, each panel string is connected to the Combiner box (including fuses) using a jumper cable (4 to 16 mm²). It can be installed on PV cables up to 1.5 kV DC. It will connect the bus cable (main side) to the jumper cables (tap side). Question: Which type of solar farm is TE’s Solar IPC P2S 240 designed for?Īnswer: Our P2S 240 is specifically designed for solar farms using a trunk bus system. The Powergel sealant is rated to 90☌ continuous temperature and is halogen-free with an extended shelf life. The GIPC-500 enclosure, with Powergel sealant, protects and seals the connection quickly and easily, saving both time and effort. In order to meet protection class II, a Powergel box can be added over the IPC (GIPC-500). The solar Insulation Piercing Connectors have been successfully tested according to EN 50483-4 and according to some specific tests defined in IEC 62852. Shear bolts always guarantee the optimum contact force without the use of a torque wrench or other special tools. The connection made by the P2S 240 on solar cables is totally watertight thanks to the elastomeric seals. A single torque control nut draws the two parts of the connector together and shears off when the teeth have pierced the insulation and made contact with the conductor strands. Metallic blades surrounded with a sealing compound ensure electrical contact for PV cables up to 1.5 kV DC. The P2S 240 connectors provide protection, insulation, and high-quality sealing of the electrical connections thanks to the Insulation Piercing Technology (IPC) that doesn't require stripping the conductor insulation before making the connection. The P2S 40 solar connectors are made with UV-stable and impact-resistant plastic raw materials. One branch connector accepts two female MC4 on the input and one female MC4 at the outputĪs a result, the number of cables is reduced from two positives to one positive and two negatives to one negative.Our P2S 240 Solar Insulation Piercing Connectors are engineered for the DC trunk bus system to connect the main side (double insulated stranded (class II) aluminum cables from 70 to 240 mm²) to tap side (double insulated flexible (class V) copper cables from 6 to 35 mm²) in operating temperature from -55☌ to +★5☌. One branch connector accepts two male MC4 on the input and one male MC4 at the output It is obvious that the two positive male and two negative females can not be connected together, that's why theh multibranch connectors will fulfill this connection. If only two panels are required the Multibranch MC4 connector is the easiest and safest method. Paralleling increases the current at max power point (Imp) while the voltage remains the same.įor example, the solar panels with 8Amps Imp and 18V Vmp, if two identical panels are connected together the amps will be 16Amps and the voltage will remain at 18V. When two panels operate in parallel the positive cables are connected together and negative cables are also shorted together.
