ACDB DCDB Box is also as Alternative Current Distribution Box (ACDB) and Direct Current Distribution (DCDB). ACDB and DCDB both are an important component of the solar system. ACDB and DCDB are basically safety circuit boxes that prevent our appliances.

AC Distribution Box (ACDB)

The ACDB (Alternative Current Distribution Box) receives the AC power from the solar inverter and directs it to AC loads through the distribution board. ACDB includes necessary surge protection device (SPD) and MCCB to protect the solar inverter from any type of damage or heavy voltage. Specifications of ACDB may change as per load or inverter capacity. ACDB provided at the cable terminating point emanating from Solar Inverter for interconnection control of dedicated electrical loads.


Array Junction Box (AJB) also known as DCDB (Direct Current Distribution Box), component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit. DCDB controls the DC power from Solar Panels and with having necessary surge protection device (SPD) and fuses to protect the solar panels strings and solar inverter from any type of damage.
