Turning off discharge

Not yet a Fox owner - but about to pull the trigger provided it has one key feature that I can’t find on the (not great) documentation. Is it possible (with HC1 inverter and ECS batteries) to stop the batteries from discharging? I have an EV without any Smart Control on the charger except for a timer and I do not want my EV to charge from the battery, only from the grid. I simply want to make sure that if I have my EV charging on a cheap overnight rate then I can stop the ESS from discharging. Is this what the force charge setting does in practice? Thank you for any help, this would be a deal breaker if the function isn't there.

Not an EV owner here, but there is a nice video on youtube about it:


so it should be possible yes.
H1-5.0-E1 inverter
ECS2900-H3
4400wp (SW) + 2000wp (NE) PV Array
HomeAssistant via WaveShare RS485 PoE to ETH (b)
no wi-fi (no stable connection)

goal: disconnect the FoxEss system from the internet completely and manage it from HA.

It absolutely does do what you'd expect. The only annoyance is that there are only two Force Charge windows to play with but this can be worked around.
