How to stop battery charging from grid
I have just had a Sunsynk 3.6kW inverter and 5kW battery, plus 7kW PV installed. The battery chargers from solar during the day and I have set the mode so that overnight the battery discharges to 10%. However on reaching 10% it then charges to 11% from grid before discharging back to 10% and keeps cycling in this way. I would like to prevent the battery charging from the grid, so that grid is then used to satisfy the load directly until PV kicks in again during daytime and recharges the battery...
What settings do I need to enable to do this?

Yipee! Those settings seem to have done the trick. The battery now discharges down to 10% (as per the SOC setting in the timers - with the grid charge disabled) and then sits there (this happened fairly early last night as we used quite a bit early evening - at 21:30) - the load being taken directly from the grid. There's a gradual usage of power to drive the inverter which makes it slowly discharge but at this point there's no grid charge happening. When it eventually hits 8% SOC, which is the same as my Low Battery setting, it does a small 1% boost charge from the grid... I'm happy I now understand how the parameters work together. Thanks to everyone who responded and helped me get there...😀
