do i need a Smart shunt?

i am building a 3 Phase ESS system using 3 Multiplus 3000 + Cerbo Gx.

i have already a Daly BMS + interface board to connect it to GX, if it works or not, i cant say, since i haven't don it yet


- do i still need a Smart shunt?

- what does a Smart shunt offer me? just monitoring or also protection?

- if it does also protection, which protections? over current? over/under voltage? over/under Temerature?


thanks in advance

You need a battery monitor in the system.
If the Daly can present its self as a battery monitor to the system then you can use that. It difficult to say if the Daly will work like this since it is not a supported BMS type.
If the Daly does not presnt its self as a battery monitor to the system then you would need to use a SmartShunt or BMV.
A SmartShunt is a monitoring device and does not offer any protection mechanisms it's self. A BMS is intended to perform the battery protection tasks.
