Was meinen wir damit? Smart Grid Charging? Oder was ist "Netzladen" hier? Es kann generell nur um das von evcc gesteuerte Netzladen gehen, nicht um Eigenleben des Speichers.

Lastmangement berücksichtigt alle Verbraucher, kann das Netzladen aber nicht unterbrechen. Der Verbrauch fließt aber sehrwohl ein!

/cc @premultiply pls check

Wenn z. B. die Hausbatterie 9 kW aus dem Netz zieht, fließt dieser Verbrauch nicht in die Lastmanagement-Berechnung ein.
Dies gilt nicht für §14a Reduzierungssignale – dort wird das Netzladen wie oben beschrieben automatisch pausiert.
:::

Optional kannst du einen maximalen Ladestand festlegen, bis zu dem die Batterie aus dem Netz geladen wird.
Erreicht die Batterie diesen Wert, wird das Netzladen automatisch gestoppt.
Die Option **Maximaler Ladestand** (`maxsoc`) findest du in der Gerätekonfiguration deines Batteriesystems.

After the power reduction ends, grid charging automatically resumes.
:::

:::warning Load Management
Home battery grid charging is not considered by [load management](./loadmanagement).
For example, if the home battery draws 9 kW from the grid, this consumption is not included in load management calculations.
This does not apply to §14a power reduction signals – in that case, grid charging is automatically paused as described above.
:::

Optionally, you can set a maximum charge level up to which the battery is charged from the grid.
When the battery reaches this value, grid charging is automatically stopped.
The **Maximum charge** (`maxsoc`) option can be found in your battery system's device configuration.
