Paramètres

Nom	Description	Niveau
`host`	IP address or hostname Exemple: `192.0.2.2`	facultatif
`capacity` [kWh]	Battery capacity Exemple: `50`	facultatif
`minsoc` [%]	Minimum charge Lower limit as configured on the battery system. Used by optimizer. Par défaut: `0` Exemple: `25`	facultatif
`maxsoc` [%]	Maximum charge Upper limit as configured on the battery system. Used by optimizer and, on some devices, for grid charging. Par défaut: `100` Exemple: `95`	facultatif
`password`	Password Service account password Par défaut: `user`	avancé
`maxacpower` [W]	Maximum AC power of the hybrid inverter Par défaut: `0` Exemple: `5000`	avancé
`battery`	Controllable battery component active battery control (REST/JSON Write Access) Exemple: `ess0`	avancé
`watchdog`	FEMS/OpenEMS battery control API timeout FEMS/OpenEMS standard 60s Par défaut: `60s`	avancé
`maxchargepower` [W]	Maximum charge power Highest power the battery system can charge with. The optimizer plans with charging up to this power. Some devices also use it as grid charging power.	avancé
`maxdischargepower` [W]	Maximum discharge power Highest power the battery system can discharge with. The optimizer plans with discharging up to this power. Smart mode assumes the battery supplies at most this power to vehicle charging.	avancé
`cache`	Cache Time interval for data refresh Par défaut: `1s` Exemple: `5m`	avancé
