The 3kW Victron Quattro is a powerful true sine wave inverter, a sophisticated battery charger and a high-speed AC transfer switch in a single compact enclosure. The bigger brother of the Multiplus range, this unit is designed for industrial and commercial systems with multiple AC sources and differential loading, in addition to larger 3-phase systems.
The Quattro can take an inputs from a generator and grid supply. It can be used in conjunction with a battery bank and solar PV inverter as an energy storage system. The unit has two AC outputs, one being programmable to only operate when shore/grid power is available; designed for heavy loads such as washing machines etc.
Up to 10 Quattro units can operate in parallel to achieve higher power output. Three phase or split phase operation is also possible.
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 54kW / 60kVA output power and 840 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 162kW / 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.
