Dear All,

we have sinamics V20 with version 3.8 that does not have MPPT function

we want to update the latest version to 3.9.1. but we don't have the update files.

can any one share the required firmware files.

thanks

Hi, I could only find this download link:

https://support.industry.siemens.com/cs/products?dtp=Download&mfn=ps&pnid=13208&lc=en-WW

It is mentioned that F09 hardware is needed. I think making a support request would help you (faster).

MPPT has been removed -  it is no longer officially supported.

Please see the newest release note:

Sales release for SINAMICS V20 Firmware V3.93.00

Files are not the same when extracted from zip?

Pleas need help with this.

New question published by AutoGen_1050053 is split to a separate thread with the subject Sinamics V20 Drive With MPPT solar Pump Application downgrading.
