Proven reliability
The full bridge plus toroidal transformer topology has proven its reliability over many years.
The inverter is short circuit proof and protected against overheating, whether due to overload or high ambient temperature.
PowerControl – Dealing with limited generator, shore side or grid power
With the Multi Control Panel a maximum generator or shore current can be set. The MultiPlus will then take account of other AC loads and use whatever
is extra for charging, thus preventing the generator or shore supply from being overloaded.
PowerAssist – Boosting the capacity of shore or generator power
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.
High start-up power
Needed to start high inrush loads such as power converters for LED lamps, halogen lamps or electric tools.
Search Mode
When Search Mode is ‘on’, the power consumption of the inverter in no-load operation is decreased by approx. 70%. In this mode the Multi, when
operating in inverter mode, is switched off in case of no load or very low load, and switches on every two seconds for a short period. If the output current
exceeds a set level, the inverter will continue to operate. If not, the inverter will shut down again.
Programmable relay
By default, the programmable relay is set as
an alarm relay, i.e. the relay will de-energise
in the event of an alarm or a pre-alarm
(inverter almost too hot, ripple on the input
almost too high, battery voltage almost too
low).
Remote on / off / charger on
Three pole connect

Two AC inputs with integrated transfer switch
The Quattro can be connected to two independent AC sources, for example the public grid and a generator, or two
generators. The Quattro will automatically connect to the active source.
Two AC Outputs
The main output has no-break functionality. The Quattro takes over the supply to the connected loads in the event of a
grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that
computers and other electronic equipment will continue to operate without disruption.
The second output is live only when AC is available on one of the inputs of the Quattro. Loads that should not discharge
the battery, like a water heater for example, can be connected to this output.
Virtually unlimited power thanks to parallel operation
Up to 6 Quattro units can operate in parallel. Six units 48/10000/140, for example, will provide 48kW / 60kVA output
power and 840 Amps 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 a ‘European’ inverter programmed to supply 240V / 60Hz.
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 144kW / 180kVA inverter power and more than 2500A charging capacity.
PowerControl – Dealing with limited generator, shore side or grid power
The Quattro is a very powerful battery charger. It will therefore draw a lot of current from the generator or shore side
supply (16A per 5kVA Quattro at 230VAC). A current limit can be set on each AC input. The Quattro will then take
account of other AC loads and use whatever is spare for charging, thus preventing the generator or mains supply from
being overloaded.
PowerAssist – Boosting shore or generator power
This feature takes the principle of PowerControl to a further dimension allowing the Quattro to supplement the
capacity of the alternative source. Where peak power is so often required only for a limited period, the Quattro will
make sure that insufficient mains 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.
Solar energy: AC power available even during a grid failure
The Quattro can be used in off grid as well as grid connected PV and other alternative energy systems.
Loss of mains detection software is available.
System configuring
– In case of a stand-alone application, if settings have to be changed, this can be done in a matter of minutes with
a DIP switch setting procedure.
– Parallel and three phase applications can be configured with VE.Bus Quick Configure and VE.Bus System
Configurator software.
– Off grid, grid interactive and self-consumption applications, involving grid-tie inverters and/or MPPT Solar
Chargers can be configured with Assistants (dedicated software for specific applications).
On-site Monitoring and control
Several options are available: Battery Monitor, Multi Control Panel, Color Control GX or other GX devices, smartphone or
tablet (Bluetooth Smart), laptop or computer (USB or RS232).
Remote Monitoring and control
Color Control GX or other GX devices.
Data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge.
Remote configuring
When connected to the Ethernet, systems with a Color Control GX or other GX device can be accessed and settings can
be changed remotely
