DCDB: Array Junction Box, DC Distribution Box
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. All switches at the circuit breakers, connectors confirm to IEC 60947, part I, II and III.

Specifications of DCDB may change as per Solar Panels or number of strings or as per site conditions.
ACDB: AC Distribution Box, AC Junction Box
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 5 KVA Solar Inverter for interconnection control of dedicated electrical loads.
TECHNICAL SPECIFICATIONS of ACDB:
| 1 | Ambient | -10 to 60 Degree C |
| 2 | Type of Enclosure | IP66 Polycarbonate Material |
| 3 | Inputs/Outputs | Single Phase ACDB, 3 Phase DCDB |
| 4 | AC Switching | MCCB/MCB Based AC Disconnection |
| 5 | Surge Protection | AC SPD Type 2 |
| 6 | Box / Top Cover | Opaque/Transparent |
Custom design is also possible as per customer requirement.
