Additionally, it can accept two AC inputs and automatically connect to the active source.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e120\/240V Input and Output, or 120V Input and Output (Always 120V Output When in Inverter Mode)\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe two AC inputs can be supplied from a split-phase 120\/240V source or a single-phase 120V source. When one of the AC sources is available, the Quattro will feed through the AC to its output. The output will therefore mirror the AC input.\u003c\/p\u003e\u003cp\u003eThe inverter\/charger connects to the neutral and the preferred input line (L1). The power needed to charge the batteries will therefore be drawn from L1.\u003c\/p\u003e\u003cp\u003eThe Quattro switches to inverter operation when no AC source is available. The inverter output is 120V single-phase. In invert mode, the Quattro connects both output lines (L1 and L2) together to provide 120VAC to loads on either line.\u003c\/p\u003e\u003cp\u003eAny 240V loads will therefore be supplied only when the Quattro is supplied by a split-phase AC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePowerControl and PowerAssist - Boosting the Capacity of the Grid or a Generator\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA maximum grid or generator current can be set. The Quattro will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function).\u003c\/p\u003e\u003cp\u003ePowerAssist takes the principle of PowerControl to a further dimension. Where peak power is often required only for a limited period, the Quattro will compensate for insufficient generator, shore, or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery (available on L1 input only).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTwo AC Inputs and Two AC Outputs\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe Quattro can be connected to two independent AC sources, for example,shore-side power and a generator, or two generators. The Quattro-II will automatically connect to the active source.\u003c\/p\u003e\u003cp\u003eThe main output has no-break functionality. The Quattro takes over the supply to the connected 120V loads in the event of a grid failure or when shore\/generator power is disconnected. The transfer time of the L1 output is less than 18 milliseconds, so computers and other electronic equipment will continue to operate without disruption. The transfer time of the L2 output is longer: approximately 40 milliseconds.\u003c\/p\u003e\u003cp\u003eThe second (auxiliary) output is live only when AC is available on the input of the Quattro. Loads that should not discharge the battery can be connected to this output.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eVirtually Unlimited Power Thanks to Parallel and Three-Phase Operation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUp to 6 Quattros can operate in parallel to achieve a higher power output. In addition to parallel connections, three units of the same model can be configured for three-phase output. In multi-phase setups, L2 is disabled on all units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOn-Site System Configuring, Monitoring and Control\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSettings can be changed in a matter of minutes with the VictronConnect app or VEConfigure software (computer or laptop and MK3-USB interface are needed).

It combines inverter and charger functionalities in a single unit, supporting 120\/240V input and output, and is ideal for off-grid systems, backup power, or integrating multiple power sources. Its ability to accept two independent AC inputs allows seamless switching between shore power and generator sources, ensuring continuous power supply with less than 18 milliseconds transfer time, which protects sensitive electronic equipment from disruptions.\u003c\/p\u003e\u003cp\u003eThis model features PowerControl and PowerAssist functions that optimize grid or generator capacity, preventing overloads while maximizing battery charging and peak power support. PowerControl limits the maximum AC input current, adjusting power usage dynamically, while PowerAssist compensates for short-term power deficits by drawing from the batteries, recharging them when loads decrease. These functionalities make the Quattro-II suitable for managing fluctuating power demands efficiently, especially in scenarios with limited or variable power sources.\u003c\/p\u003e\u003cp\u003eThe Quattro-II offers two AC inputs and outputs, with the main output providing no-break transfer functionality, ensuring continuous operation of critical loads during power source transitions. The auxiliary output is active only when AC input is available, allowing connection of loads that should not discharge the batteries. Multiple units can be operated in parallel—up to six—to scale up power capacity, or configured for three-phase output in multi-phase systems. Monitoring and configuration are straightforward through the VictronConnect app, VEConfigure software, or remote management via the Cerbo GX, enabling users to fine-tune settings and monitor system performance remotely. Constructed with a robust steel enclosure rated IP22, the Quattro-II is built for durability and safe operation in various environmental conditions, with protection against overloads, short circuits, and high temperatures. Its comprehensive specifications and flexible setup options make it an essential component for advanced power systems requiring reliable, scalable, and efficient energy management.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e120\/240V Input and Output, or 120V Input and Output with Always 120V Output in Inverter Mode\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAccepts two AC inputs from split-phase or single-phase sources with automatic source switching\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInverter mode provides 120V single-phase output with less than 18 milliseconds transfer time\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePowerControl and PowerAssist functions enable dynamic load management and peak power support\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupports up to 6 units in parallel or configured for three-phase operation for scalable power output\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMain no-break AC output ensures uninterrupted power to critical loads during source switching\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSecondary auxiliary output active only when AC is available, protecting batteries from unnecessary discharge\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRemote monitoring and control through VictronConnect app, VEConfigure software, or GX devices\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with remote internet access for system diagnostics via VRM platform\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable steel enclosure with IP22 protection, suitable for demanding environments\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":44528684597290,"sku":"100132","price":1377.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/100132XL.jpg?v=1783040714","url":"https:\/\/atticusgoods.com\/products\/victron-energy-quattro-ii-12-3000-inverter-charger-with-dual-ac-inputs-and-powerassist-technology","provider":"Atticus Goods","version":"1.0","type":"link"}
