In the firmware change log on the professional site, like it always has been.


November 2023

  • Fix noisy/erroneous fan driving for:

    • MultiPlus-II 24/3000/70-32 (PMP242305010); HQ2229 Up to and including HQ2337
    • MultiPlus-II 48/3000/35-32 (PMP482305010); HQ2226 Up to and including HQ2339
    • MultiPlus-II 48/5000/70-50 (PMP482505010); HQ2225 Up to and including HQ2317


Not all units within those serial number range are affected. To see if a unit is affected, see “202311 – MP-II serial numbers with FAN calibration issue.xlsx”.

For any affected unit, we recommend installing the firmware update. Doing that will significantly reduce the generated noise level. For all other units, there is no need to go through the firmware update process.

On the other hand, there is no harm in installing this firmware version in units which do not exhibit this error. This firmware can be safely installed on all units.

If you are doing the upgrade for fan noise

don't bother, mine are still just as loud... have a HQ2241 and a HQ2243

There's another thread that I can't find now. There was also a firmware issue on some units which is fixed by the 5.07 release.

I also get a 404 when trying to download the file. My serial number is HQ2226 so I think I'll get the latest FW installed tomorrow and see if it makes any difference. Anyone else tried it on an HQ2226?

FYI, if you link your Victron Professional account to Dropbox then the file is available successfully from Dropbox. I was able to confirm that my serial number is NOT in the list of affected inverters and so FW v507 probably won't improve my fan noise. Not a big deal because I don't find it to be a problem anyway.

My three inverters are:
- HQ2237
- HQ2238
- HQ2246
The first two are in the list, the last one isn't.

Note to self don’t update from mobile phone! It ended up not liking the saved config file in the file system on iphone, which could have been a bad day had I not saved the config via the MK3 minuets before.

HQ2301 updated fine straight from the VRM took a while to get over 41% my first update on the live system. So glad I saved it via the MK3

Haha, yeah good advice. This is actually one of the few times I use a Windows VM on my Mac. It's just easier to access VRM from the Windows browser, get the config file at the appropriate time in the upgrade cycle (I also had a copy I took on my Mac beforehand), double click the config file to initiate the conversion and then upload it straight back. I wish the VE Configure tool was available natively on the Mac but it's not a very frequent operation so not a big deal.
