Feature

  • Ingress protection of the combiner box reaches IP65, it is featured with waterproof, dust-proof,

rustproof, salt fog proof, can be used outdoors.

  • Put in 24 channels of PV strings at most.
  • Positive and negative poles of each PV string are equipped with special fuse wire,

which protects the PV string from fault, use match-able fuse holder and fuse wire to reduce later
maintenance cost for owner, and guarantee safety of maintenance personnel.

  • It uses photovoltaic purposed HV lightning protector to carry out protection to the positive

pole-to-ground and negative pole-to-ground of bus after combination,
the continuous operating voltage reaches 1000VDC.

  • The power supply module in the combiner box can accept PV voltage as high as 1000DCV.
  • The measure-control module of combiner box adopts high-performance Honeywell Hall elements (DC CT sensor), which 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.

  • 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.

  • It is equipped with RS485/MODBUS-RTU serial port communication.
  • All external interfaces have lightning protection.
  • Receive and download the parameters of local monitoring device, and carry

out analysis processing.

  • 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.
