question

The key is the Cerbo and turning on DVCC in the settings.

The system will perform as you expect, but for better control a smart shunt or BMV would help.

Sorry I'm not able to produce a circuit diagram for you. But the product manuals have good ones.

I can only echo the comment about system diagrams - there are some excellent schematics in the support section of the Victron site which will guide you to connect things together.

With regard to your specific questions:

1. When the mppt generates power - charge the battery to 100%, then use the power (mppt) to load the AC without draining the battery and over charge battery?

The first part of your question is default behaviour, the second part requires some additional work, there are some options one of which is to implement AC Ignore in the inverter.

2. When mppt is not generating power, use only AC?

Again, this is default behaviour.

3. If there is no AC grid, use mppt if exist and then battery?

Without grid the inverter will be fed by the MPPT and battery but not one then the other.

4. If AC grid exist and mppt not exist - charge batteries from inverter to 100%?

I think this is the same as your #2?

I'm not sure if it's possible, that's why I want to find the best way to connect all these devices.

Hello.

After reading the documentation I think, the connection should be like this

Can you confirm it?

My main goal is to protect the battery, when AC grid and MPPT are available.

If everything is correct I will buy the SmartShunt and get back with setting questions.

Thanks.
