A Direct Current Distribution Box also referred to as (DCBD), acts as an interlink between the Solar panels and the inverter. When the Solar panels convert the Solar energy to DC, in such a case, we use the DCDB to control the received DC from it.

The output of the DCDB is an input for the inverter. Besides, it also acts as a protective device as it contains an SPD (Surge Protection Device), MCB (Miniature Circuit Breakers), and Fuse. Moreover, the fuse is installed internally to avoid voltage spikes by directing the excess charges to the ground. Thus, it protects the Solar panel strings and Solar inverter from incurring damage. DCDBs come in different sizes based on the load.

Below are examples of onccy’s manifolds installed in European countries.
