The other category of issues is thermal: As a first explanation for observed reduced \r\nenergy yields, it has been assumed that the conversion efficiency degrades at higher operating temperatures. This \r\nmatter has been investigated in this article: A change in conversion efficiency could not be observed for elevated \r\noperation temperatures up to 50°C, despite high-precision and repeated measurements. But it was found that some \r\ninverters temporarily interrupted (or entirely stopped) operation after long periods of running at high temperatures. \r\nAlso, a reduction in potential maximum power output has been detected for those inverters. Summarizing: With a \r\nhigh degree of certainty it can be stated that those reported yield losses have been caused by the temporary shutdowns \r\nand power limitations of the inverters."}],"file":[{"content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2022-01-06T12:27:02Z","creator":"krauter","date_created":"2022-01-06T12:27:02Z","file_size":599660,"file_name":"Krauter Bendfeld - Microinverters at elevated temperatures EUPVSEC 2020.pdf","file_id":"29171","access_level":"closed"}],"publication":"Proceedings of the EU PVSEC 2020 ","title":"Elevated Temperatures Affecting Efficiency, Overall Performance and Energy Yield of PV Microinverters","date_created":"2020-08-27T06:26:25Z","year":"2020","quality_controlled":"1"}]
