Issue with Inverter in 6.4.3

[jaya]

Hi,

I have a project which has AE 500 NX -H inverter created in version 6.3.9 but the same project after updating my PVsyst to 6.4.3 is giving an error message to the project saying Inverter invalid as see in the attached image. Could you please let me know any solution to this problem.

Thank you,

Jaya

Your inverter file seems to be completely corrupted.

I don't know why, nobody has never reported this problem. Perhaps you have open it in a text editor and saved it ?

You should recreate this file from the datasheets.

Hi,

We also seem to be getting a similar issue (v6.42), when changing the inverter efficiency values. We have re-installed PVsyst a few times, however the issue seems to creep in but not for user.

The file errors out with a blank error message and appears to corrupt the file if you save after. Screenshot attached of this in progress.

Many thanks,

Grae

Please check that the "Power threshold" parameter is not null on the first page, before opening the efficiency page.

We have corrected this problem in the next versions.
