Project Summary

A solar inverter or PV inverter is a type of electrical converter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection. Our primary focus is to prototype a 100W off-grid inverter. Pre-existing inverter will be reverse engineered for this purpose. Circuit analysis would be thoroughly implemented. Doing this way various schematics and algorithms will be studied. Different hardware usage will be observed. The corresponding studies would be utilized to choose for better hardware performance. Hardware and a designed schematic will be chosen to bring the circuit on hardware. Printed circuit boards will be fabricated with parameters keeping insight of various electrical parameters. The circuits and components will be tested separately in lab.  

Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity. Now a days industrialization and Globalization is the in this technical is era is the sustainable development and environmental pollution to be addressed. The reduction of fossil fuels can lead to destructions in future. The path to secure our future progeny is to move towards the renewable resource. When it comes to renewable energy there the need of the inverter design to convert the DC Power into generated from the fossil fuels into the AC fin order to utilize it for our homes and industries. The main power to be addressed here is the power quality of inverters and switching speed of the inverter to be considered.

Technical Details of Final Deliverable

The delivered prototype will be a 100W inverter and a basic Simulink model of design. The hardware consists of transistor switches. Which are driven by a control circuit. The control system will provide essential feedbacks and measurements. A microcontroller as per the design details will be used for building a control circuit with required peripherals. After inversion necessary filtering will be done through different filter circuits. Finally, the output power will be drawn through a transformer. Major electrical parameters like voltage and current will be displayed on a digital display.

The inverter will have at least basic electrical protections and isolation. The components used i.e. Switches, Transformers, IC’s etc., will be design specific with respect to their electrical parameter ratings. The parameters may include voltage and current ratings, thermal ratings, breakdown voltage, overshoot ratings etc.

Moreover, the PCB(Printed Circuit Board) trace design will be according to required electrical ratings while considering the possible generation of electromagnetic interference. The PCB routing will be done to serve a traceable circuit with each stage clearly visible.

Design will be tested as per the required output parameters like functionality, output stability, fluctuation, power factor etc. The Test will be done under supervision of an expert or trained personnel.
