ABSTRACT

The aim of this project is to incorporate hybrid functionalities into a DSPIC30F2010-controlled inverter system. Conventional non-hybrid inverter systems are characterized by their dependency on the grid, low efficiency in solar charging, limited energy management capabilities, and ineffective communication between components. Therefore, this endeavor is designed to integrate hybrid features to overcome these shortcomings.

The process entailed designing a hybrid inverter system to address the limitations of non-hybrid inverters and to do this, we incorporated an alternative power source, i.e. solar energy, to charge the battery. This involved designing an MPPT (Maximum Power Point Tracking) charge controller and seamlessly integrating its circuitry with that of the inverter in the non-hybrid system. Additionally, we established effective communication between the DSPIC30F2010 microcontroller on the inverter and the DSPIC30F2010 microcontroller on the MPPT circuitry using serial communication, which we integrated into the inverter. All communication protocols were outlined in the source code. To ensure organization and tidiness, we housed all these components within a single enclosure.

The project successfully achieved its intended objectives by introducing hybrid features into the existing non-hybrid systems. Through meticulous design and implementation, all identified limitations were effectively addressed, leading to significant improvements in system performance and functionality. The integration of hybrid functionalities not only fulfilled the project's goals but also opened avenues for enhanced efficiency and versatility in renewable energy utilization.  Relevant tests showed optimum results for the system.
