Abstract

Among the components needed for the operation of an on-grid photovoltaic solar energy system, the photovoltaic inverter is essential. This work presents the technical and operational criteria requested for the connection of these inverters to the energy distribution power system in accordance with the current versions of the National Electricity Distribution Procedures (PRODIST), normative resolutions of the National Agency of Electrical Engineering (ANEEL), certifications of INMETRO, standards of the Brazilian Association of Technical Norms (ABNT) and international standards. In addition, a comparison of these requirements was made for each concessionaire and it concluded that all are in accordance with the current regulation, some being more detailed and demanding that the others.
