DVCC on Multi with old firmware
@BenM
As @JohnC mentioned big call. What inverter what firmware?
The Cerbo GX manual is very clear on this topic. Check out the DVCC Requirements, section Firmware version.
Minimum firmware version for a Multi/Quattro is 422. Don't use DVCC if your Multi does not meet this requirement.
Hi @BenM
Big call for a short question, The changelog is quite massive.
Sign yourself in to Victron Professional and seek it out. Happy reading..
Multi 12/3000/120-50 firmware 1900209.
I checked already before the change log after version 209.
209 is the newest version possible for 1900 serie.
As example, will DVCC work?
Will the Multi receive CVL CCL from the BMS?
I dont see this 2 points mention in the change log.
You might have issues with assistants but in theory the core capabilities should work, whether or not it is tested anymore, can't tell you but the cerbo docs state supported firmware:
The earliest version of the VE.Bus devices which can be connected to the Cerbo GX is 19xx111 or 20xx111, which were released in 2007. VE.Bus firmware 26xxxxx and 27xxxxx are also supported …but 18xxxxx is not.
edit: Stephanie has confirmed the DVCC requirements so no go there.
