ESS - prioritise battery over grid no matter what SoC the battery is

My situation is this:
EasySolar 48/3000, fw 556, grid meter
ESS is installed and configured for “optimized (without batterylife)”
Grid setpoint set to 50W
Feed-in disabled

What I am seeing is the grid being used to supplement solar to power loads during the day.

Is it possible to configure ESS to prioritise battery over grid at all times?

Above min SOC, that is what ESS does, unless you have set limits or you exceed the inverter’s spec, factoring in temperature and possible derating.

ah ok, if the Loads are above ~3000W, doesn’t the multiplus power assist?
so for say a 4kW load, the multiplus will be in inverter mode supplying 3kW and then 1kW comes from the grid (assuming solar is zero)?
