These junction boxes are compliant with IP65/IP54, depending upon location and environment. This will be helpful in fulfilling requirements like dust free, vermin free, and weatherproof. The junction box could be made from mild steel (MS) sheet metal, aluminium die cast, or thermoplastics. Low-diameter DC cables with cable glands from strings will be fed into the input side and higher-diameter DC cables from the output side of junction boxes. The junction box may be AC or DC depending upon requirements. A typical junction box is shown in Figure 9.4.

The junction box is just that—a small box where the wiring “junction” or connection is made. It is a metal container intended for easy, safe, and reliable electrical connections. It is also intended to conceal them from the elements and prevent tampering. The box is attached to the back cover of the module by means of screws and/or glue and contains connectors for wires coming from the module and those connecting it to the external circuitry.

The energy supply distribution unit obtains 48 V input voltage from the secondary junction box, and the maximum input power is 200 W. It consists of the DC/DC step-down module, anti-surge impact circuit, filter circuit, short circuit protection, over-current voltage protection, external sensor, and the internal electronic control system components. The energy supply distribution unit also provides external power output of 24 VDC with a maximum output power of 200 W. The power output is 12VDC, and the maximum output power is 150 W. The power output is 5 VDC, and the maximum output power is 100 W (Figure 4). To prevent system overheating, all power modules are equipped with heat dissipation devices.

The Solar PV system’s Power conditioning unit is its nerve center. The Power conditioning unit job is to change the direct current produced by the solar panels into alternating current. In addition to the Power conditioning unit, the MPPT element was supplied to the Input dc portion of an inverter that was made to monitor current and voltage in order to optimize input again from array. The purpose of a junction box is to combine all of the incoming lines via solar panel and provide single common outputs for the many array sources. The Junction Box’s primary functional characteristics are:
