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 system 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 live 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 shore side 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.
