Hey,
I've already asked in the German-speaking area, but unfortunately I haven't received an answer yet. :-(
So, here in English:
I've had an "EV Charging Station NS" in my Victron setting for a few days.
I control the entire system with IP Symcon and Modbus. I have already converted the EVCS to switch between 1 - 3 phases. (official modification)
There are some parameters in the Modbus Excel list that I don't understand. - Currently I am not satisfied with the steps (increasing / decreasing the charging power of the speed it changes these values of the EV charger). Sometimes it moves up too quickly and then has to reduce the power again sharply.
I would like to optimize the steps and timing.
Can someone please help and explain the following parameters?
| 5057 | Power for 3phase | uint16 | 1 to 65535 | 4800 | R/W | yes | W. Related to 'multiple relay charging' feature. |

What exactly is "Feed in" and "Battery powered"?
I hope someone can help me.
Thank you, Martin
