DCDB (Direct Current Distribution Board)
The DCDB (Direct Current Distribution Board) is a vital component in a solar power system that manages the DC power generated from solar panels before it is transferred to the inverter. It ensures safety, proper current flow, and protects the system from faults and surges.
Our DCDB units are designed with high-quality fuses, surge protection devices (SPDs), isolators, and MC4 connectors. They are tailored to fit small residential systems as well as large commercial and industrial solar installations.
Key Benefits
DCDBs play a critical role in protecting solar panels and wiring from overcurrent, reverse current, and lightning strikes. They offer better control, monitoring, and maintenance of the DC side of your solar system.

Work Process
We start with assessing your PV array configuration and inverter input specs. Then we design a suitable DCDB with the right number of inputs and safety components. Finally, we install and test the unit to ensure secure and efficient DC power distribution.
System Analysis
We analyze the number of solar panel strings and design a DCDB tailored to your inverter and system voltage.
Board Assembly
We assemble the DCDB with appropriate isolators, SPDs, fuses, and terminals to match system size and protection level.
Installation & Testing
We install the DCDB, connect the PV inputs, and thoroughly test voltage, polarity, and safety features before handover.
