The International Electrotechnical Committee Technical
Report IEC 61000-3-15:2011 provides electromagnetic
compatibility requirements and test conditions for distributed
generators up to 75 A per phase. In the current research,
two commercially available photovoltaic (PV) inverters up to
the capacity of 3600 W were tested following the guidelines
proposed in IEC 61000-3-15 in relation to low order harmonic
emission and flicker emission. In addition, the harmonic and
flicker emission behaviour of the PV inverters were investigated
under varying irradiation conditions. Both PV inverters were
observed to comply with the emission requirements prescribed by
the technical report under most conditions except for even order
harmonics, which were observed to be in excess of the stipulated
limits. Furthermore, fluctuation in solar irradiation was observed
not to have any significant impact on flicker emission of the PV
inverters under consideration.
