Automated test platform for grid-connected PV inverter certification

Since 2014 Brazilian System on Conformity Assessment (INMETRO) compelled all PV grid-connected inverters up to 10 kW sold in Brazil to comply with the rule N° 357. This rule defines 24 different conformity test procedures based on ABNT NBR Std. 16149, NBR Std. 16150, and NBR IEC Std. 62116. This paper presents the proposed automatic and systematized design procedure to conduce these tests, including experimental results.
