+      Um die aktive Ladesteuerung zu nutzen muss einmalig über das Webinterface oder App Zeiten für das Netzladen definiert werden. (Einstellungen->Funktionseinstellungen->Netzladen/Entladen) Hier sollte ein durchgehender Zeitraum (z.B: Ladezeit 1 00:00-23:00,   Ladezeit 2 23:00-00:00) eingetragen werden. Den Schalter "Netzladen" aber deaktivieren. Die eigentliche Steuerung erfolgt über evcc. Der Entladestopp wird über eine geplante Netzladung mit einem Ziel-SoC von 10% realisiert. Alternativ können die Zeiten auch über Modbus konfiguriert werden. Dafür die Register `2134,2142,2135,2136,2144,2137,2175` auf die Werte `0,0,23,0,23,0,0,0` setzen.

+      To use active battery control, times for grid charging must be defined once via the web interface or app. (Settings->Function settings->Grid charging/discharging) A continuous time period should be entered here (e.g.: Charging time 1 00:00-23:00, Charging time 2 23:00-00:00). However, deactivate the "Grid charging" switch. The actual control takes place via evcc. Discharge stop is realized via a scheduled grid charge with a target SoC of 10%. Alternatively, it can also be configured via Modbus. To do this, set the registers `2134,2142,2135,2136,2144,2137,2175` to the values `0,0,23,0,23,0,0,0,0`.
