Solar AC Distribution Box (ACDB)

 •> The main purpose of the ACDB is to eliminate the operation of the load at the immediate PCU O/P end and also provide flexible operation of different loads like Street lights, general home or office lights and optional loads that optionally operated (On/Off).

DC Distribution Box (DCDB)

•> The DC Distribution Box is used to provide flexibility for the operator of the solar power plant to disconnect and connect both the inward solar supply and battery terminals. Here an MCCB and a fuse of proper rating depending upon the capacity of the power plant and the battery bank are used.
•> In the DCDB we have two sections one is the solar section and the other is the battery section.
Solar Section/ Battery Section
•> In solar section the incoming terminals from the MJB are fed to the input connectors and the conduction path takes place through the MCB and a HRC Fuse of proper rating selected as per the system capacity and the panel used in the power plant. The same is done for the incoming terminals from the battery bank.
