Combiner Box

Combiner Box provides a means of combining multiple source circuits from a PV array into a single DC output. Each source circuit is fused separately using a touch-safe fuse holder. The combiner box allows for fail-safe operation of the system in the unlikely event that a problem with a source circuit leads to abnormally high current.

In addition, the combiner box provides a convenient means of accessing the DC portion of a PV system for routine maintenance and troubleshooting.

The PV array lightning protection box has the following characteristics:

(1) meet the requirements of outdoor installation, protection class IP65, with anti-UV, anti-acid, anti-alkali, moisture, mildew, rodent control and other functions;

(2) Access 16-way PV array, each with 15A, 1000Vdc fuse (replaceable other grades);

(3) Equipped with special high-voltage lightning protection device, lightning protection function with cathode and anode ;

(4) Positive, negative string into the fuse;

(5) Use quadruple PV dedicated circuit breaker with positive and negative in series

Specifications:

IP65 DC 1000V 8 10 12 16 24 string solar PV combiner box for solar power system

1. 4ways~52ways, IP65 waterproof

2. DC 1000V, 60A~780A

3. Polyester, vertical wall mounting, High quality

1. Ingress protection of the combiner box reaches IP65, it is featured with waterproof, dustproof, rustproof, salt fog proof, can be used outdoors.

2. Put in 24 channels of PV strings at most.

3. Positive and negative poles of each PV string are equipped with special fuse wire, which protects the PV string from fault, use matchable fuse holder and fuse wire to reduce later maintenance cost for owner, and guarantee safety of maintenance personnel.

4. It uses photovoltaic purposed HV lightning protector to carry out protection to the positive pole-to-ground and negative pole-to-5. ground of bus after combination, the continuous operating voltage (Uc) reaches 1000VDC.

5. The power supply module in the combiner box can accept PV voltage as high as PV Intelligent Lightning Protection Combiner Box.

6. The measure-control module of combiner box adopts high-performance Honeywell Hall elements (DC CT sensor), which 8. carries out monitoring, alarm and local fault location to each PV string, meanwhile, it measures the temperature inside the combiner box, carries out status inspection to the lightning protector and output circuit breaker.

7. Monitoring module in the combiner box has function of digital display, it indicates the current of each PV string, bus voltage, temperature inside the box, status of circuit breaker and lightning protector, system power, equipment address and other relevant information.

8. It is equipped with RS485/MODBUS-RTU serial port communication.

9. All external interfaces have lightning protection, Solar power generation system solar panel combiner box.

10. Receive and download the parameters of local monitoring device, and carry out analysis processing.

11. Working power supply for combiner box can be 220VAC/DC from outside, also can be supplied by the self-contained power supply of combiner box. When using the self-contained power supply, users need not to arrange additional wiring for the power supply, Solar power generation system solar panel combiner box supply.
