Quattro Inverter/Charger

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.
