Conducted electromagnetic interference has shown to result in misreadings of static energy meters due to non-linear current waveforms. Based on these findings it is of interest to survey waveforms that occur in typical low voltage distribution networks, and to which static energy meters are exposed to. Therefore, complex waveforms in a domestic photovoltaic installation are identified. Furthermore, discrepancies between the generated power, consumed power by the loads and drawn power from the grid are found. This paper aims to correlate these waveforms to the observed discrepancies in the power consumption data and survey the waveforms that occur in these modern installations.
