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. The maximum alternating current that can be
switched is 16A or30A, depending on model.
Virtually unlimited power thanks to parallel operation
Up to 6 Multi's can operate in parallel. Six units 24/3000/70, for example, will provide
15kW / 18kVA output power and 420 Amps charging capacity.
Three phase capability
Three units can be configured for three-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.
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':
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.
Solar energy
The MultiPlus is extremely suitable for solar energy applications. It can be used in
autonomous systems as well as grid connected systems.
