Junction Box - Solution to Convey Power in Solar Plant

Array Junction Box is one of the major component of Solar Photovoltaic System. It is also termed as combiner box suitable for various solar power applications. It links the outcoming strings of solar panel to incoming strings of solar inverters. The strings of inputs and outputs sounds analogous to that of a multiplexer which also has multiple input and a single output. Multiple incoming strings from solar panel array are combined and the solar energy is transmitter to the inverter through a single output. According to the number of strings at the termination of PV Array, the input ports of the junction box can be customized. Range of output strings available are 1-24 and the peak current flow is 30Amp/String. Array Junction Box is a cost effective and reliable gadget. The whole setup is perfectly engineered to provide protection from harmful factors such as over-current, short-circuit, etc.

Components of combiner box:

• Enclosure: Enclosure is made of finest quality polycarbonate which can withstand harsh climatic conditions. It comes with IP65 degree of protection and can be of variable sizes depending on the input strings and the safety features enclosed inside the box.
• PV fuse: To provide over current protection, Combiner box can be equipped with a neutral link or a fuse as an additional pack depending on the version you choose.
• Surge Protection Devices: SPDs is installed to limit the voltage entering the device to a value that the device can withstand. Pluggable surge protection units are included for solar power applications rated from 600 to1000 volt DC.
• DC Isolator: For any kind of maintenance work on the solar inverter, isolator switches can be used to disconnect the DC Side.
• Clock boxes: It can maximize the performance of the device.
• Additional accessories: Current sensors are optional for measuring the flow of current through the strings. Another add on can be indicators to monitor the continuous operation of the system.
