The Victron Quattro is a battery inverter and charger combined into one unit. Off-grid power systems with a Quattro can operate multiple electrical draws without overloading the AC power source, and deliver continuous uninterrupted power in the event of power failure.
Each Quattro is a true sine wave inverter, providing clean power for sensitive electronics. It is also a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact enclosure.
The Quattro can be connected to two independent AC sources, for example shore-side power and a generator, or two generators. The Quattro will automatically connect to the active source.
The main output has no-break functionality. In the event of a grid failure, or shore or generator power being disconnected, the Quattro takes over the supply to the connected loads. 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, such as air-conditioning or a water heater can be connected to this output.
The Quattro will prevent overload of a limited AC source. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.
Up to 6 Quattros can operate in parallel to achieve higher power output. Three phase or split phase operation is also possible.
