TUV-R 71830-01: Microinverters and MicroconvertersSCOPE:TUV-R 71830 describes the design qualification and type approval requirementsfor microinverters and microconverters for long-term operation in general openair climates. The standard aims to determine minimum requirements for qualityand reliability of the microinverters and microconverters and to show that theyare capable of withstanding prolonged exposure in open air climates.10

TUV-R 71830-01: Microinverters and MicroconvertersNEED:‣ Qualification standards for modules exist‣ Qualification standards for module level power conditioners do not exist‣ Module level power conversion devices undergo higher level environmentalstresses as compared to central/string inverters (hotter environment on theback of the module!)‣ Sample size and stress tests may have to be different as compared to stringand central inverters11
