Two AC inputs with integrated transfer switch
The Quattro can be connected to two independent AC sources: for example, to the public power grid and to a generator or to two generators. The Quattro automatically connects to the active source.

Two AC outputs
The main output ensures uninterrupted operation. In the event of a power outage or a disruption of the land/generator power, the Quattro takes over the supply for the connected consumers. The switching occurs so quickly (in less than 20 milliseconds) that uninterrupted operation of computers and other electronic devices is guaranteed. The second output only provides power when AC is available at one of the Quattro's inputs. Consumers that must not discharge the battery, such as a water heater, can be connected to this output.

Practically unlimited.
