AC and DC Distribution Boxes
ACDB (AC Distribution Box) and DCDB (DC Distribution Box) are essential electrical components in solar power systems, designed to manage and protect the flow of current between the solar panels, inverters, and the grid/load. DCDB handles the DC power from solar panels before it reaches the inverter. ACDB manages the AC output from the inverter to the load/grid, ensuring safety, monitoring, and control.

Products Description
Both boxes come equipped with MCBs, fuses, surge protection devices (SPDs), and terminal blocks. Built with IP65/IP66-rated enclosures, they are dustproof, weatherproof, and suitable for harsh outdoor conditions.
ACDB and DCDB: What are they?
Direct Current Distribution Box (DCDB): The first distribution box of a solar power system is also referred to as an Array Junction Box (AJB). Between the solar panels and the solar inverter, it is installed. Managing and safeguarding the direct current (DC) power produced by the solar panels is its main duty.
After the solar inverter, the ACDB (Alternating Current Distribution Box) is fitted. Its function is to distribute and control the alternating current (AC) electricity that has been transformed from DC power by the inverter. After that, the AC power from the ACDB can be routed into the main electrical grid or used to power appliances in a house or building.
