摘要

One of the main promises of solar photovoltaic technology has been the use of so-called microinverter which intends to make it possible for anyone to produce their own power generation.This article presents a discussion of a proposal to adapt the Brazilian Standard NBR 16274(photovoltaic systems connected to the network—minimum requirements for documentation,commissioning tests,inspection and performance evaluation)of grid-connected photovoltaic(PV)system design methodology-oriented inverter module(or microinverters).The article begins by presenting the different methodologies grid-connected PV system projects discussing positive and negative aspects of each.Then search presents a discussion of the positive and negative aspects of grid-connected PV system design methodology with microinverters,giving a practical example of design.The paper is organized as follows:Section 1 provides an introduction explaining the importance of the proposed methodology;Section 2 presents the different types of grid-connected PV system design methodology as well as its positive and negative aspects;Section 3 describes the key differentiators of grid-connected PV system design methodology with use of microinverters finished with practical example of scaling;Section 4 presents the main proposals to adapt and points on conflict of NBR 16274;Section 5 presents the work’s conclusions.
