Brazilian grid-connected photovoltaic inverters standards: A comparison with IEC and IEEE

This paper discusses the Brazilian photovoltaic grid-connected inverters standard comparatively with their European and North American counterparts. The electrical characteristics between the photovoltaic grid-connected inverter system and the electrical distribution network, required by the ABNT NBR 16149 standard, are described in detail. A comparison with its related standards in Europe (IEC Std. 61727) and United States (IEEE Std. 1547) is carried out, and finally is presented the standards implications.
