Solar Distribution Box (DCDB/ACDB) instead of Solar Junction Box

We offers array junction (DC distribution) boxes, string monitoring boxes, AC distribution boxes and low voltage electrical distribution and protection panels customized for solar PV applications. Our products use IP65 rated enclosures, and DC and AC switchgear from leading global manufacturers such as ABB, Schneider, and Mersen, and are designed to meet international electrical standards. Features offered under these products are described below:

These boxes provide interconnection between input leads from the solar module arrays and the output leads to the inverter. These boxes are customized for different configurations based on the series-parallel configuration layout of the solar array. Common features of these boxes include:

  • Compatible with 600V-1500V DC solar PV installations
  • DC inputs can range from 1 to 24 based on number of inputs
  • Standard box configurations available for rooftop installations
  • Customized boxes manufactured for utility scale MW solar installations
  • DCDBs use IP65/66 polycarbonate/GRP enclosures suitable for outdoor installations, with flammability and impact protection
  • Input and output cable connectors can be provided through IP65 cable glands or MC4 connectors
  • Overcurrent protection for individual PV strings through PV fuses
  • Protection against surge currents on DC side through SPDs
  • DC MCBs/switches to disconnect DC generation and prevent export of power to AC side during maintenance
