Page 5: Description
MultiPlus-II 48V 3kVA 120V 2. Description 2.1. Boats, vehicles and other stand-alone applications The basis of the MultiPlus-II 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 MultiPlus-II will switch over to inverter operation and take over the supply of the connected devices. -

The MultiPlus-II synchronises within this range with the AC input frequency. The output frequency is then equal to the input frequency. Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz Input voltage range Voltage range accepted by the MultiPlus-II.
- Page 20 MultiPlus-II 48V 3kVA 120V The standard setting is the most suitable for Victron Gel Deep Discharge, Gel Exide A200, and tubular plate stationary batteries (OPzS). This setting can also be used for many other batteries: e.g. Victron AGM Deep Discharge and other AGM batteries, and many types of flat-plate flooded batteries.
