I tested it, and this works fine now. Thank you for the clarification!
PS: I still have an issue with the EVCS starting with low excess PV, see my other question. The two influence each other, e.g. at the end of the day when PV is running low, the EVCS gets into a few cycles of stopping (because it was discharging house batteries) and starting again because “waiting for sun” is met at 1.4 kW (which my panels almost always give, unless it is really dark).
