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)
