2. DESCRIPTION
2.1 In general
The basis of the MultiPlus is an extremely powerful sine inverter, battery charger
and automatic switch in a compact casing.
The MultiPlus features the following additional, often unique characteristics:
Automatic and uninterruptible switching
In the event of a supply failure or when the generating set is switched off, the
MultiPlus will switch over to inverter operation and take over the supply of the
connected devices. This is done so quickly that operation of computers and other
electronic devices is not disturbed (Uninterruptible Power Supply or UPS
functionality). This makes the MultiPlus highly suitable as an emergency power
system in industrial and telecommunication applications.
Virtually unlimited power thanks to parallel operation
Up to 6 MultiPlus units can operate in parallel. Six units 24/3000/70, for example, will
provide 15kW / 18kVA output power and 420 Amps charging capacity.
Three phase and split phase capability
Three units can be configured for three-phase or split phase output. But that's not all:
up to 6 sets of three units can be parallel connected to provide 45kW / 54kVA inverter
power and more than 1000A charging capacity.
Split phase options
Two units can be stacked to provide 120-0-120V, and additional units can be
paralleled up to a total of 6 units per phase, to supply up to 30kW / 36kVA of split
phase power.
Alternatively, a split phase AC source can be obtained by connecting our
autotransformer (see data sheet on www.victronenergy.com) to an 'European' inverter
programmed to supply 240V / 60Hz.
PowerControl – maximum use of limited shore current
The MultiPlus can supply a huge charging current. This implies heavy loading of the
shore connection or generator set. Therefore a maximum current can be set. The
MultiPlus then takes other power users into account, and only uses 'surplus' current
for charging purposes.
PowerAssist – Extended use of your generator and shore current: the MultiPlus
"co-supply" feature
This feature takes the principle of PowerControl to a further dimension allowing the
MultiPlus to supplement the capacity of the alternative source. Where peak power is
so often required only for a limited period, the MultiPlus will make sure that insufficient
shore or generator power is immediately compensated for by power from the battery.
When the load reduces, the spare power is used to recharge the battery.
This unique feature offers a definitive solution for the 'shore current problem':
electric tools, dish washers, washing machines, electric cooking etc. can all run
on 16A shore current, or even less. In addition, a smaller generator can be
installed.
