Parametre

Navn	Beskrivelse	Niveau
`host`	IP address or hostname Eksempel: `192.0.2.2`	valgfri
`capacity` [kWh]	Battery capacity Eksempel: `50`	valgfri
`minsoc` [%]	Minimum charge Lower limit as configured on the battery system. Used by optimizer. Standard: `0` Eksempel: `25`	valgfri
`maxsoc` [%]	Maximum charge Upper limit as configured on the battery system. Used by optimizer and, on some devices, for grid charging. Standard: `100` Eksempel: `95`	valgfri
`password`	Password Service account password Standard: `user`	avanceret
`maxacpower` [W]	Maximum AC power of the hybrid inverter Standard: `0` Eksempel: `5000`	avanceret
`battery`	Controllable battery component active battery control (REST/JSON Write Access) Eksempel: `ess0`	avanceret
`watchdog`	FEMS/OpenEMS battery control API timeout FEMS/OpenEMS standard 60s Standard: `60s`	avanceret
`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.	avanceret
`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.	avanceret
`cache`	Cache Time interval for data refresh Standard: `1s` Eksempel: `5m`	avanceret
