AC Distribution & Protection Box
The ACDB (AC Distribution Box) sits between the solar inverter’s AC output and the main distribution board. It houses the AC MCB (Miniature Circuit Breaker), AC SPD (Surge Protection Device), and output terminals, providing the first line of overcurrent and overvoltage protection on the AC side. Vidyut Renewables manufactures ACDB boxes in-house, allowing us to tailor the component rating to each inverter’s exact output capacity.

AC Distribution & Protection Box
The DCDB (DC Distribution Box) sits between the solar panel strings and the inverter DC input. It consolidates multiple panel strings, provides individual fuse protection for each string, and houses the DC SPD (Surge Protection Device) that shields the inverter from lightning strikes and switching transients. Like our ACDB, the Vidyut Renewables DCDB is manufactured in-house, with fuse ratings matched to the panel string short-circuit current of each specific project.
