The Quattro 48/5000 is an inverter and charger with two AC inputs that automatically connects to the active input.

Features of the Quattro 48/5000 include a pure sine wave inverter, variable load, hybrid PowerAssist technology, plus multiple features for integration into different systems, such as three-phase or split-phase systems.

The Quattro can be connected to two independent AC power sources. The main output has a "no-break" function (no switch). In the event of a power failure, or disconnection from the mains or generator, the Quattro takes over the supply of the connected loads. The second output is only active when one of the Quattro's inputs is AC powered.

The Quattro can prevent overloads on a limited AC source, such as a generator or a port socket. First, it will automatically reduce the battery charge when an overcharge occurs. Secondly, it will draw current from the battery to compensate for power from the generator or the mains.

Up to 6 Quatters can be connected in parallel to achieve a higher power output. Operation in three-phase or split-phase mode is also possible.
