What are your settings on the Solar Production Page? Have you tried the No Import Preset?

I primarily charge my EV off-peak from the grid, but I am trying to setup to divert excess solar power to charge my EV. I have the MQTT running successfully, showing the PV production and the EVSE is adjusting the current accordingly. The issue I have is making it shut off when the available current drops below 6 Amps. Since it doesn't shut off it starts drawing down my system batteries. Did I miss something in the setup, or is there no built in way to only use the excess solar power for EV charging?
Background info: I'm in the US, I am running Home Assistant with all solar components from Victron, dual inverters for split-phase. I am do not have a grid-tied system, no back feeding just batteries. The system is installed in an RV, but currently it is at home plugged into the grid. All EV charging goes through the RV.
