Abstract:
In order to facilitate the installation of PV systems, it is expected that power optimizers and microinverters will be integrated in the PV module, the so-called Smart PV module. For integrated electronics in PV modules no IEC standard is available yet, but it is likely that the damp heat test at 85°C and 85% relative humidity of the IEC 61215 standard for type approval of PV modules will be part of a future standard for PV modules with integrated electronics. In this paper the results are given of the add-on power optimizer PO310 of Femtogrid and SMI-300 microinverter of Heliox as tested at 85°C and 85% relative humidity, without power and under power conversion. The test under power conversion appeared to be even more severe for part of the components. The power optimizer of Femtogrid passed the damp test without power conversion for 1000 hours, followed by 500 hours with power conversion. The Heliox microinverter also passed the damp heat test during 500 hours with power conversion as no power degradation was observed.
