The DC Distribution Board (DCDB) is a vital component of a solar photovoltaic (PV) power plant. It is installed between the solar PV modules and the inverter to provide safe, reliable, and efficient DC power distribution.

This specific DCDB is designed to handle 12 input strings and 12 output strings, making it suitable for medium to large-scale solar installations. Each incoming string from the solar panels is individually protected by a fuse or DC MCB and then combined into a single output string going to the solar inverter.

The DCDB provides overcurrent, overvoltage, and surge protection, ensuring the longevity of solar equipment and safety of maintenance personnel.
