  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
