Quattro-II
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 system integration features such as three or split phase operation and parallel operation.

Models:24/5000/120-50 and 48/5000/70-50

Product Characteristics

Two AC Inputs & two AC Outputs

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.

Unique PowerAssist feature

The Quattro 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.

Applications

Household Energy Storage

Backup systems seamlessly switch over from (failing) grid power to battery power so fast you and your most critical appliances won’t even notice. The system is sized to power the critical loads during the expected ‘down times’. Solar energy can extend the up-time and if needed, a generator can be seamlessly integrated, minimising their usage automatically by prioritising solar energy.
