Zero Feed-in: which modbus option is correct?

there are several topics about zero feed in, but none really answers my question.

I want to set "zero-feed-in" via Modbus.

but there are more options, how to do that:


1. set register 2706 "Maximum System Grid Feed In" to 0W

2. set register 2707 "Feed excess DC-coupled PV into grid" to 0

and at same time set register 2708 "Don’t feed excess AC-coupled PV into grid" to 1

3. set register 39 "ESS disable feedback flag phase" to 1


I have tested option 1 and 2 so far, which seem to work.

But is there a difference between those options?! Or are all options acceptable and will lead to the same result?

Or is there a special and preferred way to do it?


BTW:

i also noticed, that even if i use option 1 or 2 for zero feed in, the grid set point is still "valid"

If i use a gridset point of e.g. -100W, the multis still would feed in, even if register 2706/2707/2708 would basically not allow it.

So to make "zero feed in" really work, you also need to change the gridset point to 0 or a positive value.


thanks!
