Mixing Pylontech 3000 and 3000C using LV-Hub

Hi,

Extending a Pylontech battery from 4 US3000 to 4xUS3000 + 8xUS3000C using an LV-HUB. Connecting to Cerbo GX via BMS cable type B. So far not able to make the Cerbo see all 12 batteries (Total capacity and live currents) at the same time. I can get up to 8 batteries showing by eliminating the LV-HUB from the setup. I can also get 8 showing with the HUB but not 12.

I realise the LV-HUB comms set up is very different for US3000 and US3000C. Hence I have also tried to create 2 stacks of 4 3000C followed by 2 x 3000. This means each stack is limited to 6, and both stacks are using 3000C as master battery. No joy getting both stacks to show on the Cerbo. (Even though one stack does show)

Has anyone managed to mix US3000 and US3000C with a Cerbo GX in a single system ?

I'm out of options but still keen to be able to monitor and control charging as a single 12 battery system via Cerbo GX

Any hints / tips / suggestions welcomed,


MK

Use a US3000C as master, then all four US3000's, then the rest of the US3000C's. No LV Hub required.

You're the man, ;) It worked. And yes I realized its all about counting in binary with someone that can only count to 8. Thanks, MK
