Pylontech setup compatible with the Victron ecosystem ?

Hello there.

I have a Multiplus II 5000 VA with 2 MPPT 250/60 (with a VE direct port)(I will add a 3rd string / 1 MPPT 150/30 in two weeks giving 8.2 kWp of PV modules) and a Pylontech Force L2 (3 modules or 10.65 kWh) linked via a Lynx DC distributor and controlled via a Cerbo GX.

Is it possible to add 2 Pylontech modules Force L1 with their own BMS to this system ? The Cerbo GX has 2 BMS Can inputs: can it control or be controlled by two (Force L1 and Force L2) Pylontech BMS ? If yes, I would just need a 2nd Lynx since the 1st one is full (already 4 DC IN).

Cheers from Liguria and a nice sunny day today

The CerboGX has one BMS Can interface. The are two physical connectors on the Can interfaces to allow daisy chaining. If the CerboGX is at the end of the chain then a terminator is placed in the open connector.
Only one BMS per system.
Not sure if L1 modules can be linked to L2 modules in a stack, ask Pylontech about that one.

Thank you for the answer. To be sure I understand, I should see wether I can link my current Force L2 stack from LinkPort1 to the new Force L1 stack's Linkport0 ? The L2 stack would then be the master, in charge of the communication with the Cerbo GX via the BMS Can port, and the L1 stack would be the controlled slave. Both the two stacks would have their power cables wired to a Lynx DC distributor.
