Development of an electrical characterization device for single-phase pv grid-connected inverters

(in lingua inglese)

A measurement system to characterize grid-tied inverters in accordance with international standards was developed at GER UNNE. This system is able to test inverters with nominal power up to 4.4 kW, although this limit can be expanded up to 10 kW by replacing the AC current probe. The comparison of the results obtained with the developed system to the results from a test facility at LABSOL-UFRGS indicated that the error in the efficiency evaluation remained below 1% for partial loads above 10% of the nominal power.
