Schedule between "keep batteries charged" and "self-consumption" in the ESS program

Good morning. Can someone please suggest me to schedule the change the state between "keep batteries charged" and "self-consumption" in the ESS program? Let me explain better, living in a country on the equator with 12 hours of sunshine and 12 hours of darkness a day all year round, I would like to use self-consumption during the day but switch to "keep the batteries charged at night.

My installation:

Victron Quattro 10KW 48V

Frunius 8.2

10Kw solar pannel

Small battery bank 200Ah (which will later be increased ).

Currently everything works well in "Keep the battery charge", and I'm happy, but during the day I waste a lot of energy coming from the panels, and at the same time I wish the batteries were 100% charged at night.

Kind regards

panels, and at the same time I wish the batteries were 100% charged at 
night.

And you want to keep the battery charged at 100% during all night (so not discharged unless there is a grid failure), or you use the energy from the battery during the night?

I am not sure if node red allows for scheduled changes of ESS mode.

I know there are no modbus registers for these settings so would be interested to know if this is possible, as well as changing the value of ESS inverter limit, one way or another.

I have questions for this in the modifications section but have received no answers.

@Guy Stewart (Victron Community Manager) anyone from team victron that can help with these queries?

Opss I had missed this question :-(

In the end I decided to increase the battery with No 6 powerwall 48v 200ah each. I hope to solve the problem. (fingers crossed).

Thanks @Seb71
