Product Introduction of 16 in 1 PV Combiner Box

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 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 system.

4. When choose 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 Specifications

2.    Allowable maximum 24 strings panels to connect, Nominal voltage of each string is 10A, maximum 15A

3.    Total output current is 250A, the maximum voltage is 1000Vdc

4.    For each string, high voltage fuse protection and anti-connection protection.

5.    Equipped with pv high voltage arrester protection

6.    PV high voltage circuit breaker control the output, pressure-resistant DC1200V, fusing current is optional

7.    In line with outdoor installation, protection class IP65

8.    Isolate RS485 port used for remote data communication, support MODBUS-RTU protocol.

9.    Built-in comprehensive protection alarm function, not only the various 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, alarm will work and directly make the trip switch and cut off fault circuit, accordingly, prevent the fire disaster etc from the arc.
