● 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 48/5000/70, for example, will provide 27kW / 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 81kW / 90kVA inverter power and more than 1260A charging capacity.
● Split-phase options
Two units can be superimposed to obtain 120-0-120V and can be connected in parallel up to 6 additional units per phase to provide a power of up to 30kW / 36kVA in split phase. A split phase AC source can also be obtained by connecting our autotransformer to a "European" inverter programmed to supply 240V / 60Hz
●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 (40A per 5kVA Quattro at 120VAC). 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 FV and other alternative energy systems.
●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
Configuratorsoftware.
- 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).
● System configuration can not be simpler
Once installed, the Quattro is ready to go.
If you have changed the settings, you can do in the question of minutes using a new procedure of setting the DIP switch. With the DIP switches you can even program the operation in parallel and three-phase: no need for a computer!
You can also use a VE.Net instead of the DIP switches
And there are sophisticated programs available (VE.Bus Quick Configure and VE.Bus system configurator) to configure several new and advanced features.
