Victron Quattro 48/10000/140-100/100 230V VE.Bus -QUA481030010

High-capacity 48 V inverter/charger (10 000 VA) with dual AC inputs, automatic transfer switch, PowerAssist & parallel/three-phase ready, ideal for off-grid and backup systems.

High output capacity: Delivers up to 10 000 VA continuous AC power from a 48 V DC bank, enabling large loads or system coverage. Dual AC inputs with auto-switching: Accepts two independent AC sources (grid and generator) and transfers seamlessly to the active one, maintaining supply stability. No-break main output plus auxiliary output: Main output handles critical loads with uninterrupted supply, while the second output can serve less-critical loads without draining the battery. Smart power management (PowerControl/PowerAssist): Avoid overloading limited AC sources and boost weak supply using stored battery power when needed. Scalable and future-proof: Compatible with lithium-ion batteries, supports parallel and three-phase configurations, plus remote monitoring via GX and VRM. Dimensions: 470 x 350 x 280mm Weight: 51kg

Product Details

Introducing the Victron Quattro 48/10000/140-100/100 230 V VE.Bus (Model QUA481030010), a robust and flexible inverter/charger built for demanding off-grid, backup power or self-consumption systems. This unit is designed for a 48 V DC battery bank and delivers up to 10 000 VA continuous AC output at 230 V.

Crafted in an aluminium enclosure finished in Victron’s signature blue, the unit combines durability and efficient performance. It supports dual AC inputs (for example grid and generator) with an integrated transfer switch that automatically connects to the active source, preventing interruption to critical loads.

On the output side, two AC outputs are provided: the main has no-break functionality, switching in under 20 milliseconds in case of a supply failure, while the second is live only when one AC input is present, making it ideal for loads that must not draw on the battery.

Advanced features such as PowerControl (to limit input current when using shore power or generator) and PowerAssist (to boost a weak source by supplementing from the battery) help you make the most of your system’s power. The Quattro supports parallel and three-phase operation, enabling scalable power systems.

Ideal for solar plus storage, commercial backup or home self-consumption systems, this inverter/charger also offers remote monitoring and control when paired with Victron’s GX devices and the VRM portal.

Installation-friendly and engineered for performance, the Quattro brings a powerful single-box solution to system integrators and homeowners alike.
