How to switch from ESS to powerassist mode (external)

Gents,

I have a question, and hope you can help me.

We have the following components:

- Multiplus II 24/3000/70/32

- Cerbo

- MPPT 100/30 (with 2 395wp solar panels)

- BMV712

- Digital control.

- 500Ah (C5) 24VDC flooded tubular plate battery.

- Generator. With 2 simple relais switching between grid or generator supply to the Victron multi.

De installaties is running on ESS, works fine!

I want to use powerassist. I understand that powerassist and powerlimit is not working (as designed ) in combination with ESS. Therefore my question: how to switch from ESS mode to "normal mode" with powerassist? Preferbly by means of an external switch ( for example on the cerbo of multiplus).

Already thanks for jour creative solutions and options ;).

Regards Mark

Not possible. The unit has to be programmed to use ess so the assistant would have to be removed to make the idea work.

So unless you have a clever piece of software that can do that with a trigger input....

You can kind of get it to power assist if you ou the input current limit right down on input and limit battery charging from the genny, but really the quattro is a better solution.
