Solar Panel Distribution Junction Boxes PV Array 1-24 String DC Combiner Box¹

Product Description 1-24 Strings Combiner Box PV Array Combiner Box Solar Junction BoxPV combiner box for the on-grid solar system  PV combiner box for the off-grid solar system PV combiner box for the solar pump system 1. In the solar power system, in order to decrease the connecting line, easy maintenance, reduce losses, optimize system structure, improving the safety and reliability of items, the PV combiner box is usually in need between the solar panels and inverter.2. Except the PV junction function, the pc combiner box should also have reverse current prevention, over-current protection, over-voltage protection, lightning protection, etc a series of perfect protection functions, meanwhile, checking the running state, current, voltage, and power after the junction, arrester state, collection of DC circuit breaker state and Arc detection, leakage detection(optional) and so on.3. The PV combiner box we manufacture is equipped with all the functions mentioned above, configuration with on-grid/off-grid solar inverter to make up a complete set of solar power systems.4. When choosing the PV combiner box, based on the input dc voltage range and output power of inverter, certain qty of panels will be connected in series as a string, certain strings in parallel will connect to the PV combiner box for junction, via control of circuit breaker and protection of arrester, then feed to the inverter. Main Feature:1. Conform to CGC/GF002:2010, PV Array Junction Box Technical Specifications2. Allowable maximum 24 strings panels to connect, Nominal voltage of each string is 10A, maximum 15A3. Total output current is 250A, the maximum voltage is 1000Vdc4. For each string, high voltage fuse protection, and anti-connection protection.5. Equipped with PV high voltage arrester protection6. PV high voltage circuit breaker control the output, pressure-resistant DC1200V, fusing current is optional7. In line with outdoor installation, protection class IP658. Isolate RS485 port used for remote data communication, support MODBUS-RTU protocol.9. Built-in comprehensive protection alarm function, not only the variety of alarm parameters are programmable set, but also each alarm function can be set "On" Or "Off)10. Real-time the harmful arc in the DC circuit, once there is the harmful arc, an alarm will work and directly make the trip switch and cut off fault circuit, accordingly, prevent the fire disaster, etc from the arc.ModelCSPVB/24-1Electric parameterSystem maximum DC voltage1000V1000Maximum input current for each string15AMaximum input strings24Maximum output switch current360AMaximum inverter MPPTNNumber of Output strings1Lightning protectionCategory of testGrade 2 protectionNominal discharge current20kAMaximum discharge current40kAVoltage protection level3.8kVMaximum continuous operating voltage Uc1050VPoles3PStructure characteristicPlug-push moduleSystemProtection gradeIP65Size of the input waterproof terminalPG9/PG11Size of the output waterproof terminalPG21~PG29Output switchDC circuit breaker (standard)/DC isolation switch (optional)MC4R Waterproof ConnectorsStandardPV DC fuseStandardPV surge protectorStandard Monitoring module(optional)Detect current of each channel, bus voltage, the status of circuit breaker and lightning protector, box temperatureAuxiliary power supplyAuxiliary power supply: AC85V~265V/DC24V(±10%)/DC200V~1000VCommunication mode/protocol(optional)RS485 bus/standard MODBUS-RTU protocolPrevent-reverse function (optional)Can be equipped with a modularized and encapsulated prevent-reverse diodeBox materialHot galvanized steel/stainless steel/cold rolled sheetInstallation methodWall mounting typeOperating Temperature-40°C ~ + 85°CAltitude4kmPermissible relative humidity0-95%, no condensation no corrosive gasMechanical parameter Width x High x Depth (mm) 850x500x200
