I have a Multiplus II installation v459 with venusGX and 2 existing Pylontech US2000. Now a new US2000C is installed soon. Some questions still before i will do the installation.
* Is it important to update the Multiplus?
* Pylontech said that the C-Model needs to be the master and the others as slave.
* Is it correct that the CAN-Bus cable needs an update in terms of Pin1-3 should not be linked anymore between Pylontech Master and VenusGX ?
Kind Regards

Yes, it is recommended to update all firmwares and fully recommission the system when making a significant change like this.
Yes, the C model needs to be the master.
The C model uses the Victron CANBUS Type A cable, not the Type B that the US2000 used.
I am using the B cable connected to US2000C and it is working!
Thats because i got an replacement battery from pylontech and this was a new C Model. Before i only had B Models. So i connected the existing B Cable to the C-Model Battery and it was working normal.
Thanks a lot. Jesus - why can't they keep things easy. How did the Type A-Cable change from the Type B-Cable.....is this the rumor'ed pin1-3 issue i read in a techrelease.
Would that work to simply remove / cut wire 1-3 from a typeB-cable???
Do you have maybe a wire coloring of a type B-cable so the cutting less of a lottery :-)
