Product Description

Array Junction Box(AJB):

Array Junction Box is meant for combining all the incoming lines from the solar panel strings/arrays and deriving one common array output for the multiple array inputs.

Main Functional Features of The Array Junction Box:

To Block the reverse flow of current from the battery to solar panels during nights or low radiation levels.
To obstruct the sudden surges due to lightening strokes during cloudy and rainy conditions and ground the surges immediately.
Efficient String Monitoring - Optional
Disconnect DC at the sources
Fuses for overload protection on each string
Blocking Diodes for reverse current flow protection
Easy DC-termination
Easy and decent Cable management
Time effective as well as money effective for cabling
Step by step trouble shooting methodology
contemporary DC combining and disconnecting
Space saving and orientation flexibility
Load-break rated disconnecting
Increased granularity
Traditional DC combining
Reliable electric safety to avoid hazard
Online Monitoring* (Optional for DCDB/ACDB)
