Hi @NEilE,

Technically, maybe, yes.

BUT I really do not recommend it.

The Pylontech BMS is doing more than just communicating the state of charge to the Cerbo GX. It is also sending charge and discharge current limits and more.

There are only specific configurations that Pylontech will allow their battery to be installed with in order to maintain their warranty. Basically if the battery says stop charging via the BMS, the rest of the system needs to be able to respond to that message (in a way that has ben tested and approved by Pylontech).

Just connecting the Cerbo GX will show you the state of charge, but running the system like that without the control is likely to void the battery warranty, and lead to other control and reliability issues.
