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.
Monitoring Section of DCDB
The DCDB is provided with a digital Ampere Hour meter to observe the charging/discharging currents of the battery i.e. Ah of the Battery.
This meter is intended to work only on the AC external supply from the ACDB feeder.
