# Alpha ESS Storion SMILE

Source: https://docs.evcc.io/en/meters/alpha-ess-storion-smile

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`.

Supported features: battery-control
