Victron Quattro 24 Volt / 5000 VA Pure Sine Wave Inverter/Charger With 120 Amp Charger

The Victron MultiPlus and Quattro series of pure sine wave inverter-chargers are some of the most feature-rich models we've seen. Besides being well-made, compact, and affordable, they do it all. Their primary features are:

• Stackable for single phase, split phase, or three phase service.
• Integrated transfer switches (Quattro models will select from two AC inputs).
• High output dual bank battery charger, which can be regulated to accommodate small generators.
• Power Assist, which supplements generator or shore power with inverter power when load requires.
• Extensive remote monitoring and control availability.
• Configurable with PC or Mac using the MK3-USB Interface (sold separately) or via dipswitches (configuration options via dipswitch highly limited)

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.

Split phase and three phase capability
Two units can be configured for split phase, and three units can be configured for three phase output. But that’s not all: up to
4 sets of three units can be parallel connected to provide 96W / 120kVA inverter power and more than 1600A charging
capacity.

PowerControl – Dealing with limited generator, shore side or grid power
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.
