  1. Hi,

    I'm trying to work out if the Enphase microinverter data from the latest PVsyst is accurate.

    This is the latest spec sheet from them

    https://enphase.com/sites/default/files/2021-08/IQ7A-UK.pdf

    The DC input side looks like this:

    INPUT (DC) IQ7A-72-2-INT

    Commonly used module pairings¹ 295 W–460 W +

    Module compatibility 60-cell / 120-half-cell and 72-cell / 144-half-cell modules

    Maximum input DC voltage 58 V

    PV input operating voltage range²18 V–58 V

    Min/Max start voltage 33 V / 58 V

    Max DC short circuit current (module Isc)³ 15 A

    Overvoltage class DC port II

    DC port backfeed current 0 A

    Then that little (2) on the input operating range has this note:

    2. EU peak power tracking voltage range is 38 V to 43 V.

    Does this mean that in PVsyst I should be changing the parameters as in attached picture?

    If I do that, then the min voltage for pnom and maximum input current become N/A
