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 or 50A, depending on
model.
Auxiliary AC output
Besides the usual uninterruptable output, an auxiliary output is available that disconnects its load in the event of battery operation.
Example: an electric boiler that is allowed to operate only if the genset is running or shore power is available.
Virtually unlimited power thanks to parallel operation
Up to 6 MultiPlus units can operate in parallel. Six units 48/5000/70, for example, will provide 24kW / 30kVA 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
72kW / 90kVA inverter power and more than 1200A 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':high power 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.
Solar energy
The MultiPlus is extremely suitable for solar energy applications. It can be used in autonomous systems as well as grid connected
systems.
Autonomous operation when the grid fails
Houses or buildings with solar panels or a combined micro-scale heating and power plant or other sustainable energy sources have a
potential autonomous energy supply which can be used for powering essential equipment (central heating pumps, refrigerators, deep
freeze units, Internet connections, etc.) during a power failure. A problem is however that grid connected sustainable energy sources
drop out as soon as the grid fails. With a MultiPlus and batteries, this problem can be solved in a simple manner: the MultiPlus can
replace the grid during a power failure. When the sustainable energy sources produce more power than needed, the MultiPlus will
use the surplus to charge the batteries; in the event of a shortfall, the MultiPlus will supply additional power from the battery.
Programmable relay
The MultiPlus is equipped with a programmable relay that by default is set as an alarm relay. The relay can be programmed for all kinds
of other applications however, for example as a starter relay for a generator.
Programmable with DIP switches, VE.Net panel or personal computer
The MultiPlus is supplied ready for use. Three features are available for changing certain settings if desired:
- The most important settings (including parallel operation of up to three devices and 3-phase operation) can be changed in a very
simple manner, using DIP switches.
- All settings, with exception of the multi-functional relay, can be changed with a VE.Net panel.
- All settings can be changed with a PC and free of charge software, downloadable from our website www.victronenergy.com
