Abstract/Summary
The objective of this project is to demonstrate the capabilities of a Raspberry Pi when used as a grid-tied, bi-directional power inverter for renewable energy storage applications. Due to its economical nature, this system would play a large role in the growing solar industry by making solar energy more accessible, affordable, and easier to install. The inverter uses a single-phase H-Bridge to generate a sine wave from a proprietary wall mounted battery. To improve power quality, an enhanced low pass filter is added to provide a better drop off to reduce extraneous harmonics. The system synchronizes this synthetic sine wave output with the incoming grid frequency through a PID that controls a Phase Locked Loop (PLL). However, the Raspberry Pi proved incapable of this task due to being unable to power the drivers to run the switching circuit.
