    MultiPlus 230V 2. Description 2.1. Boats, vehicles and other stand-alone applications The basis of the MultiPlus is an extremely powerful sine inverter, battery charger and transfer switch in a compact casing. Important features: Automatic and uninterruptible switching In the event of a supply failure or when the generating set is switched off, the inverter/charger will switch over to inverter operation and take over the supply of the connected devices.

    MultiPlus 230V 3. Operation 3.1. On/Off/Charger Only Switch When switched to ‘on’, the inverter/charger is fully functional. The inverter will come into operation, and the LED ‘inverter on’ will light up. An AC voltage connected to the ‘AC in’ terminal will be switched through to the ‘AC out’ terminal, if within specifications. The inverter will switch off, the ‘mains on’...
