Solar ACDB Box
The ACDB (Alternative Current Distribution Box) is a small solar device that is installed between the solar inverter and your home load. An ACDB includes necessary surge protection devices (SPD), AC fuse, and MCB to protect the appliances from any type of electrical damage or high voltages.
It receives the AC power from the solar inverter and directs it to AC loads through the distribution board. The AC fuse inside the box will melt and break the circuit in case of high voltage or excess electricity supply. It prevents your appliances from being damaged. Single phase ACDB is used in solar systems with capacities up to 6kW, while three phase ACDB is used in higher capacity solar systems.
