Fronius Symo 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) 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).

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.
