Parameters

Name	Description	Level
`host`	IP address or hostname Example: `192.0.2.2`	optional
`capacity` [kWh]	Battery capacity Example: `50`	optional
`minsoc` [%]	Minimum charge Lower limit as configured on the battery system. Used by optimizer. Default: `0` Example: `25`	optional
`maxsoc` [%]	Maximum charge Upper limit as configured on the battery system. Used by optimizer and, on some devices, for grid charging. Default: `100` Example: `95`	optional
`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.	advanced
`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.	advanced
