A Solar ACDB (AC Distribution Box) is an essential component in a solar power system that serves to distribute and manage the AC (alternating current) power generated by the solar inverters before it is fed into the main power supply or grid. The ACDB is typically installed between the inverter output and the load or grid connection point. It protects the system from faults, overloads, or other issues on the AC side, thereby ensuring safe and reliable operation.

• Protection: It safeguards the system from overloads, short circuits, and surges using fuses, circuit breakers, and surge protection devices (SPDs).
• Distribution: AC power from the solar inverter is routed through the ACDB to the building's loads or to the grid. It can serve multiple loads and provide selective isolation.
• Monitoring: Many ACDBs are equipped with meters to monitor the AC power output, allowing users to track system performance and energy production.
• Isolation: The ACDB allows for the solar system to be safely disconnected from the loads or grid, which is critical for maintenance and repairs.
