Hello,
Does anyone know why the MPPT is limiting the voltage to 52.40V?
It says limited due to BMS but BMS is reporting 58.4V as the limit.
Battery will not charge above 35%.
Thank you

@mvader (Victron Energy) Is there anyway to remove the 52.40V limit and it follow the BMS voltage? I am happy to terminal in and edit files.
That's what pylons are limited to, so if you have a third party BMS spoofing a pylon you will be limited to that by DVCC. 58.4V definitely isn't a pylon so presumably some DIY/3rd party concoction off the compatibility list.
Yeah, it is not a pylontech battery but is using pylon protocol. It is a 16S pack not 15S like the pylons.
Best (if you can) set it to spoof a different BMS on the support list.
The battery is a black box, I unfortunately can't change any of it's settings.
Once it identifies as a Pylon all the settings are forced on.
I found the file.

You can edit the file to increase the voltage. I have edited up to 58.00V and now I can change the DVCC menu to set the voltage I would like.
Thanks @nickdb for clarifying the cause.
You can use your script too
