Multifunctional
Similar to the MultiPlus-II, the Quattro-II is also a combined inverter and charger. Additionally, it can accept two AC inputs and automatically connect to the active source. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology plus multiple systems integration features such as three or split-phase operation and parallel operation.
Two AC Inputs & two AC Outputs
The Quattro-II can be connected to two independent AC sources, for example, shore-side power and a generator, or two generators. The Quattro-II 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-II 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 life only when AC is available on one of the inputs of the Quattro-II. Loads that should not discharge the battery, such as air-conditioning or a water heater can be connected to this output.
Unique PowerAssist feature
The Quattro-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shoreside supply with power taken from the battery.
Virtually unlimited power thanks to parallel operation
Up to 6 Quattros-II can operate in parallel to achieve higher power output. Three-phase or split phase operation is also possible.
