Unsure about accuracy of Enphase IQ7A microinverter data in PV Components Posted January 20, 2022 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 themhttps://enphase.com/sites/default/files/2021-08/IQ7A-UK.pdfThe DC input side looks like this:INPUT (DC) IQ7A-72-2-INTCommonly used module pairings¹ 295 W–460 W +Module compatibility 60-cell / 120-half-cell and 72-cell / 144-half-cell modulesMaximum input DC voltage 58 VPV input operating voltage range²18 V–58 VMin/Max start voltage 33 V / 58 VMax DC short circuit current (module Isc)³ 15 AOvervoltage class DC port IIDC port backfeed current 0 AThen 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

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
