But i dont want it to charge from the grid. is it not possible for the inverter to just stop drawing any power from the battery and leaving it at the set SOC and rather switching over completely to grid?

Then the inverter will not hold the batteries. Even the batteries BMS and internal resistances will drain them slowly. If you don't want the grid to hold them then set SOC% a bit higher for more margin.

Yeah thats what ive been doing. seems a bit silly though to be able to set a minimum SOC but the inverter will drop it below the so called minimum. if i want 30% SOC at 4am due to loadshedding i currently need to set my SOC at approximately 40% in order to be safe.
September 29, 20223 yr Are you on the latest firmware ? i found my SOC dropping much slower after the upgrade ,i think they made it consume more of the stand by power from the grid than from battery.

If you don't have PV you will pay the same one way or the other. It doesn't take a lot from the grid to hold the batteries. I would do that to be safe.

Hi @Nexuss. just requested the upgrade earlier today. will see how it goes...

I hope your upgrade solves it. All devices with battery do in fact use battery power to be on alert to operate as you want it. You can't expert the battery not to provide the power or keeping it at the specified level not using from the grid.
