Protection and distribution boxes for every size of solar plant
Synchro Electricals manufactures ACDB (AC Distribution Box) and DCDB (DC Distribution Box) panels for solar power installations, including commercial rooftops, industrial solar plants and utility-scale projects.
ACDB and DCDB panels perform different functions within a solar PV system. DCDB panels provide DC-side distribution and protection, while ACDB panels manage AC-side distribution and protection after the inverter.
Panel selection depends on system voltage, current, inverter configuration, protection requirements and installation conditions.

What is an ACDB in a solar power plant?
An ACDB is an AC Distribution Box used to distribute and protect alternating current on the output side of a solar inverter.
What is a DCDB in a solar power plant?
A DCDB is a DC Distribution Box used for DC-side distribution, isolation and protection within a solar PV installation.
What is the difference between ACDB and DCDB?
An ACDB handles alternating current after the inverter, while a DCDB handles direct current on the PV side of the system.
Can ACDB and DCDB panels be customised?
Yes. Configurations can be developed according to the project’s electrical drawings, voltage, current, protection requirements, and installation conditions.
What information is needed for a quotation?
Share the solar plant capacity, inverter details, single-line diagram (SLD), protection requirements and installation specifications.
