A Main Junction Box (MJB) is used to combine the multiple outputs from multiple numbers of Array 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).
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.
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: Array Junction Box has mainly 2 duties to be performed,
Agriculture in India is affected by unpredictable rains and unreliable power supply. Diesel based power is of high cost per unit and is increasing significantly in proportion with the oil prices.
Solar Water Pumping Systems are ideal solution for the agricultural needs as water is required for the crops during day time and there is no or minimal requirement of water during nights.
Govt. of India is offering various schemes in the form of subsidy to benefit the farmers who are setting up Solar Water Pumping Systems.
Novus Green offers Solar Water Pumps staring from 1 HP to 10 HP capacities available in both AC & DC type. We are empanelled with MNRE & NABARD to Promote Solar Water Pumping Program where NABARD is providing subsidy & loan to the customers.
Our Solar Water Pumping Systems are tested and have excellent performance record with cost effective solutions. So far we completed over 150 installations in India.
Benefits & Advantages
The PCU is the heart of the Solar PV system. The function of the PCU is to convert the direct current (DC) generated by the PV arrays to Alternating Current (AC).
The PCUs manufactured by the Novus Green come with Intelligent Solar Sensing (ISS) technology and are offered in different capacities ranging from 1 KVA to 25 KVA.

The main purpose of the ACDB is to eliminate the operation of the load at the immediate PCU O/P end and also provide flexible operation of different loads like Street lights, general home or office lights and optional loads that optionally operated (On/Off).
Specification Description
The DC Distribution Box is used to provide flexibility for the operator of the solar power plant to disconnect and connect both the inward solar supply and battery terminals. Here an MCCB and a fuse of proper rating depending upon the capacity of the power plant and the battery bank are used.
In the DCDB we have two sections one is the solar section and the other is the battery section.
Solar Section/ Battery SectionIn solar section the incoming terminals from the MJB are fed to the input connectors and the conduction path takes place through the MCB and a HRC Fuse of proper rating selected as per the system capacity and the panel used in the power plant. The same is done for the incoming terminals from the battery bank.
Monitoring Section of DCDBThe DCDB is provided with a digital Ampere Hour meter to observe the charging/discharging currents of the battery i.e. Ah of the Battery.
This meter is intended to work only on the AC external supply from the ACDB feeder.
