Fronius Primo GEN24 Plus

← PV, Battery, Grid, Meter

To use active charge control, the Energy Cost Assistant (ECA) must not be activated in Fronius Solar.web. (Fronius Solar.web -> Settings -> Operating Mode -> Self-Consumption)

Supported features

Battery control: External control of home battery charging and discharging via evcc.
Curtailable: Inverter production can be reduced (e.g. § 9 EEG). See External Limit.

Parameters

Name	Description	Level
`host`	IP address or hostname Example: `192.0.2.2`	optional
`port`	Port Default: `502`	optional
`capacity` [kWh]	Battery capacity Example: `50`	optional
`minsoc` [%]	Minimum charge Lower limit as configured on the battery system. Used by optimizer. Example: `25`	optional
`maxsoc` [%]	Maximum charge Upper limit as configured on the battery system. Used by optimizer and for grid charging. Example: `95`	optional
`id`	ID Meter address of primary or secondary meters. On the web interface of the inverter, only the address of the first meter (e.g., 200) can be set. Additional meters receive an ascending number (e.g., 201). Default: `200`	advanced
`maxchargepower` [W]	Maximum charge power For forced charging of the battery.	advanced
`maxdischargepower` [W]	Maximum discharge power Maximum discharge power of the storage.	advanced
`maxchargerate` [%]	Maximum charge rate For forced charging of the battery in percent in relation to the maximum charge power of the battery inverter. Default: `100`	advanced
