On model 447.7 (with CODE ZH6 (Marco Polo ACTIVITY)), the voltage converter control unit 12 V, 230 V (T4) is available as special equipment.

Function sequence for DC/AC converter 

If a consumer is connected to the socket, voltage is switched through to the control input of the voltage converter control unit 12 V, 230 V. The voltage converter control unit 12 V, 230 V converts the direct voltage of the on-board electrical system into AC voltage. A calculation method stored in the voltage converter control unit 12 V, 230 V prevents the inverter from constantly switching between on and off when it gets close to either limit value. If undervoltage is detected by the energy management system, the voltage converter control unit 12 V, 230 V is switched off and the power supply to the socket is interrupted. If a consumer is connected to the socket, voltage is switched through to the control input of the voltage converter control unit 12 V, 230 V. The voltage converter control unit 12 V, 230 V converts the direct voltage of the on-board electrical system into AC voltage.
