MultiPlus II AC IN

I look for someone to guide me on the adjustment of the Victron Multiplus II 48V/8000VA.
I have almost finished the installation and I am in the first test stage.
THE QUESTION IS:
What parameters of the inverter should I modify, to supply the loads from the batteries when the AC IN is connected to the public network.
When the batteries discharge 50%, the power of the batteries is interrupted,
and LOADS (on AC OUT 1) to connect to the Public Network.
The adjustments will be made with MK3-USB.

Thanks in advance.

@Daaf

Ess and a GX (yes the mk3 as well) are needed.

Under ESS on the GX you tell the system ac output not in use

Without more details hard to advise.

Be aware the inverter is rated at VA not W - You cant power max load for long. You can restrict the inverter e.g. 5000W, but this also depends on the bat bank and its maximun discharge potential.

Also depending if you use external or internal meter. With the internal meter the inverter will try to power any demand from the battery first before using additional power from the grid if restricted, with an external meter it is the other way round first use grid then ramp up bat supply to match demand or restriction

When you hit SOC no more bat will be used except on grid failure.

See the above mentioned ess manual depending on bat setting the system will increase SOC automatically if you hit it regularly.

Here's a few options: https://youtu.be/4ZsGHi8nKGc

Just a heads up there's some info in the description about something being configured backwards.
