Product Description

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.

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).

Features

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 DCDBIACDB)

Main Functional Features of The Main Junction Box

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.
Efficient String Monitoring Optional
