EV Charger current/power based on excess energy

[arctic gull]

Hi,
I wanted to figure out if it's possible to regulate my Wallbox's current/power delivery based on excess power in a system with a (solis) inverter with modbus-tcp already working connected to solar panels and batteries.
Both the wallbox and inverter's entities are already properly configured inside home-assistant.
Thanks

Do you have an entity to regulate the charge rate?

Hi. The current of the wall box is writeable thus the power is also manageable

Heres how i do mine
