Abstract :
Test results of 6 commercial inverters for grid connected PV systems in the power range up to 5 kW are given. The considered aspects include: energy efficiency, power point tracking efficiency, start-up power, power quality, conformity to EMC standards, acoustic noise and susceptibility to electromagnetic noise. The results are obtained with the PV test facility of ECN. The results show that in the last few years considerable progress has been made concerning the performance of grid connected inverters which are available on the European market. In general the efficiency is over 88% over a wide power range, with a peak efficiency of about 92%. Most inverters comply with standards concerning power factor, harmonics, EMC and acoustic noise
