This model QUA485021100 Quattro 48/5000/70-100/100 120V VE.Bus uses a 48V Battery, Outputs 5000 VA VA (Volt Amps) are similar to watts but include reactive losses to give you a more realistic load capability. A 2000 VA unit will operate a 2000 watt resistive load but will decrease when running motors. Similar to the MultiPlus, the Quattro 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:3000VA, 5000VA, 8000VA, 10000VA, 15000VA Two AC inputs with integrated transfer switch The Quattro can be connected to two independent AC sources, for example the public grid and a generator, or two generators. The Quattro will automatically connect to the active source. Two AC Outputs The main output has no-break functionality. The Quattro takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. 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, like a water heater for example, can be connected to this output. Split phase and three phase capability Two units can be configured for split phase, and three units can be configured for three phase output. But that’s not all: up to 4 sets of three units can be parallel connected to provide 96W / 120kVA inverter power and more than 1600A charging capacity. For more detail please enter parallel in the search box on our website. PowerControl – Dealing with limited generator, shore side or grid power A current limit can be set on each AC input. The Quattro will then take account of other AC loads and use whatever is spare for charging, thus preventing the generator or mains supply from being overloaded. PowerAssist – Boosting shore or generator power This feature takes the principle of PowerControl to a further dimension allowing the Quattro to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, the Quattro will make sure that insufficient mains or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is used to recharge the battery. Solar energy: AC power available even during a grid failure 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. System configuring – In case of a stand-alone application, if settings have to be changed, this can be done in a matter of minutes with a DIP switch setting procedure. – Parallel and three phase applications can be configured with VE.Bus Quick Configure and VE.Bus System Configurator software. – Off grid, grid interactive and self-consumption applications, involving grid-tie inverters and/or MPPT Solar Chargers can be configured with Assistants (dedicated software for specific applications). On-site Monitoring and control Several options are available: Battery Monitor, Multi Control Panel, Color Control GX or other GX devices, smartphone or tablet (Bluetooth Smart), laptop or computer (USB or RS232). Remote Monitoring and control Color Control GX or other GX devices. Data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge. Remote configuring When connected to the Ethernet, systems with a Color Control GX or other GX device can be accessed, and settings can be changed remotely.
