Array Junction Boxes (AJB), also referred to as PV combiner boxes, basically collect DC power from PV strings with blocking diodes on each string for protecting panels from reverse current flow. The collected power is then transferred to power inverter.

Array Junction Box

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

• 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)
