ACDB stands for Alternating Current Distribution Box. It is a critical component that manages the distribution of alternating current (AC) electricity generated by solar inverters to various electrical loads in a building. Functionality: The ACDB includes protective devices such as AC Surge Protection Devices (SPDs) and Miniature Circuit Breakers (MCBs). These components help protect the system from power surges and overloads, ensuring safe operation. Importance: By controlling the flow of AC power, the ACDB enhances the efficiency of solar energy utilization and integrates solar power into existing electrical systems. DCDB stands for Direct Current Distribution Box. It is installed between the solar panels and the inverter, serving as a protective interface for the direct current (DC) generated by solar panels. Functionality: The DCDB contains devices such as DC SPDs, DC MCBs, and fuses that protect the solar inverter and panels from high voltage and short circuits. This ensures the safety and reliability of the solar power system. Importance: The DCDB plays a crucial role in safeguarding the solar system from faults and surges, thereby enhancing the longevity and performance of solar installations.
