This was my final year project for my BEng degree. The idea for this project came from the problem that certain South African prepaid meters bill the residence for the power they generate into the grid. This project investigated a temporary workaround for this problem, by diverting the net outflow of power into a resistor bank, the extra cost would then be minimized. This project consisted of some simple power electronics, C programming for the micro-controller and some electronic system design.
