Parametre

Navn	Beskrivelse	Værdi	Niveau
`id`	Modbus-ID Standard: `1`	int	påkrævet
`host`	IP-adresse eller værtsnavn Eksempel: `192.0.2.2`		påkrævet
`port`	Port Standard: `502`	int	påkrævet
`battery`	controls battery component active battery control (Modbus/TCP Write Access) Standard: `false`		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
`grid_power_register`	Modbus register for grid power GridActivePower (W) Standard: `315`		avanceret
`grid_energy_register`	Modbus register for grid import energy GridBuyActiveEnergy (Wh) Standard: `359`		avanceret
`pv_power_register`	Modbus register for PV power ProductionActivePower (W) Standard: `327`		avanceret
`pv_energy_register`	Modbus register for PV energy ProductionActiveEnergy (Wh) Standard: `367`		avanceret
`maxacpower` [W]	Maximum AC power of the hybrid inverter Standard: `0` Eksempel: `5000`		avanceret
`battery_power_register`	Modbus register for battery power EssDischargePower (W) Standard: `415`		avanceret
`battery_soc_register`	Modbus register for state of charge SoC (%) Standard: `302`		avanceret
`battery_set_register`	Modbus register for charge power SetActivePowerLessOrEquals (W) Standard: `710`		avanceret
`watchdog`	battery control API timeout 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
