The Quattro has two AC Inputs & two AC Outputs meaning two independent power sources can be connected, such as a generator or mains power. The Quattro automatically selects the input where voltage is present with the generator input taking priority.

PowerControl is a valuable feature, especially when handling limited power such as generator supply. When the Quattro draws significant current from the generator or shore side supply, set the maximum current limit on each AC input. Considering other loads, the Quattro adapts so that only surplus power is used for charging, thus preventing the generator or mains supply from being overloaded.

The PowerAssist feature will enable the device to supplement the incoming power with power from the battery. Any excess power is used for charging. It is therefore no longer necessary to size a generator on the maximum peak load. Use the most efficient size generator instead.

The automatic and uninterruptible switching will ensure that if the power supply fails, the device will switch over to inverter operation so fast that loads will be unaffected, making this device an ideal choice for emergency power situations and telecommunications applications.

For three-phase operation, three units can be configured, and additionally, potentially unlimited power supply can be achieved with the Multiple System Integration function, which allows for up to 6 Qattros [24/3000/70, for example], to operate in parallel providing 15kW / 18kVA output power and 420 Amps charging capacity.

For split phase operation, two Quattros would be stacked to provide 120-0-120V, and additional units can be paralleled up to a total of 6 units per phase, to supply up to 30kW / 36kVA of split phase power.

The Quattro can be used in off grid as well as grid connected PV and other alternative energy systems. Loss of mains detection software is available.

Configuring parallel and three-phase systems is made simple with the VEConfigure software tool - the Interface MK3-USB is required.
