    .This means that energy can be drawn from the home network and fed into the battery via the Fronius inverter (battery support required). You can restrict how much power is consumed by the Fronius inverter by specifying the maximum AC power (AC max.). A maximum power consumption of the AC rated power of the Fronius inverter is possible.
