We are instrumental in offering our clients highly functional Solar String Combiner Boxes. This Solar String Combiner Boxes, which we offer, are fabricated with the use of latest technology and are suitable for different Solar Power applications. Our Combiner Boxes is properly tested by the experts under strict industry norms to guarantee flawless functioning and durability. Also known as Array Junction Boxes (AJB), these Solar String Combiner Boxes have 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.

GEESYS Solar Junction Boxes
Introduction
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 Junction Box (MJB) : A Main Junction Box (MJB) is used to combine the multiple outputs from multiple numbers ofArray 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).
