Solar ACDB is an AC distribution board used after the solar inverter to control, distribute, and protect AC power before it reaches the LT panel or connected load. Solar DCDB is a DC distribution board used on the photovoltaic string side to collect or protect DC power before it is routed toward the inverter. Together, Solar ACDB DCDB panels form an important part of safe solar electrical design for rooftop solar, commercial solar, and larger solar PV power plants.
The basic difference between ACDB and DCDB is the side of the project where they are installed and the type of current they handle. DCDB works on the DC side of the plant and typically includes fuses, SPD, isolator, terminals, and MC4 connector arrangements for string inputs. ACDB works on the inverter output side and commonly includes SPD, MCB, MCCB, isolator, contactor, and suitable output termination for downstream distribution. This organized protection arrangement helps improve maintenance safety and structured power evacuation.
Solar ACDB DCDB panels are used in rooftop solar systems, commercial buildings, industrial solar projects, and utility-scale solar plants where the inverter and connected loads require reliable switching and surge protection. Depending on project size, the panel can be customized with 1 in 1 out, 2 in 1 out, 4 in 1 out, and 6 in 1 out arrangements. The build can include SPD, MCB, MCCB, fuses, isolator, terminals, MC4 connector interface, and enclosure ratings from IP21 to IP65 depending on indoor or outdoor installation needs.
