I have done exactly that (just a different charger, but you should be able to use this)

You can read about it and download the flow in this thread:

> Surplus solar energy charging Only use the surplus of your solar energy to charge your EV. To minimise your energy returned to grid. Restrictions: EV’s generally require a minimum of 6A (1.4kW) to start charging Current adjustment is at 1A resolution so you will not always get 0 (1A = 220W ) The flow supports dynamic phase switching between 1 and 3 phases (Switching does require a Off+On of the Amina to be effective) Below is my flow (which is also usable for other chargers, with adaption…

It works perfect keeping the current close to zero (resolution of setting the curent is 1A, so you will always have a bit of overshoot)
