ACDB (AC Distribution Box) and DCDB (DC Distribution Box) are essential components of solar power systems, responsible for the efficient distribution of electrical power. ACDB (AC Distribution Box) An ACDB is a crucial component in a solar power system that distributes AC power generated by the inverter to various loads. It acts as a junction box, ensuring safe and efficient power distribution. Key Components of an ACDB: MCB (Miniature Circuit Breaker): Protects the circuit from overcurrent and short circuits. Earth Leakage Circuit Breaker (ELCB): Protects against electrical shock by detecting and interrupting earth leakage currents. Surge Protection Device (SPD): Protects the system from voltage surges and spikes. Metering Units: Measures the power consumption and generation. Key Functions of an ACDB: Power Distribution: Distributes AC power to various loads like lights, fans, and appliances. Circuit Protection: Protects the system from faults and overloads. Monitoring: Provides real-time monitoring of power consumption and generation. DCDB (DC Distribution Box) A DCDB is a critical component in a solar power system that distributes DC power generated by solar panels to the inverter. It ensures safe and efficient power flow within the DC side of the system. Key Components of a DCDB: DC Circuit Breakers: Protect the DC circuits from overcurrent and short circuits. Surge Protection Devices (SPDs): Protect the system from voltage spikes and surges. DC Connectors: Connect the solar panels to the DCDB. Fuse: Provides additional protection to the circuit. Key Functions of a DCDB: Power Distribution: Distributes DC power from solar panels to the inverter. Circuit Protection: Protects the DC circuits from faults and overloads. Monitoring: Provides real-time monitoring of DC voltage and current. By understanding the role of ACDBs and DCDBs, you can ensure the efficient and reliable operation of your solar power system.
