A Main Junction Box (MJB) is used to combine the multiple outputs from multiple numbers of Array Junction Boxes in the Power Plant and form a single output that can be connected directly to the DC Distribution Board (DCDB) or Power Conditioning Unit (Solar Inverter). The main important features of the Main Junction Box are to provide a single output. The MJB consists of two bus bars. One is used to combine all the positive terminals and the other is used to combine the negative terminals.
