A configuration option to set a time after the battery may start charging.
It would support the morning peak load in the grid, if the battery does not start charging as soon as local solar panels produce enough power but wait until 11am or so before loading, when there is enough or often even too much power in the grid.
E.g. sending out max. 0W power (instead of the actual e.g. +30W power) to the battery until charging time is reached.
