Hey! Ohme EV charger - don’t drain my solar battery!

Thinking of entering the world of home assistant mainly for one reason only as described below.

When my OHME EV charger is scheduled to charge overnight; I’d like it to instruct my SOLIS INVERTOR to place my home battery on standby and this preventing it completely discharging .

Currently I have to manually go into the solis app and set a fake charging period through a 10 step process to stop it the battery discharging.

Thanks in advance
