xVictron Quattro 48/10000/140-100/100 230V VE.Bus Inverter Charger — QUA481030010
The Victron Quattro 48/10000/140-100/100 is a 10kVA inverter charger designed for demanding off-grid, backup and hybrid installations. It accepts two independent AC inputs, manages battery charging at up to 140A, and provides two separately controllable AC outputs. It is suited to professional installers working on large residential, commercial or marine systems where reliable power management and generator integration are required.
Key Features
- 10kVA continuous inverter output at 230V AC, suitable for high-load applications.
- Two AC inputs allow simultaneous connection of mains grid and a generator, with automatic transfer switching between them.
- 140A battery charger built in, operating on a 48V battery bank.
- Two AC outputs: AC Output 1 is an uninterruptible supply (no break on mains failure); AC Output 2 disconnects when running on battery, allowing non-essential loads to be shed automatically.
- VE.Bus communication interface enables multi-unit parallel and three-phase configurations, as well as integration with Victron GX devices and the VictronConnect ecosystem.
- PowerControl and PowerAssist functions prevent overloading a limited AC source by drawing supplementary power from the battery bank when demand exceeds the input current limit.
- Programmable relay and comprehensive protection against over-temperature, overload and short circuit.
Product Overview
The Quattro series sits above the MultiPlus range in Victron's inverter charger lineup. The defining difference is the dual AC input. Where a MultiPlus accepts one AC source, the Quattro accepts two independently configurable inputs, each with its own current limit setting. In practice, this means you can connect a grid supply to Input 1 and a generator to Input 2. The Quattro will prioritise the grid, switch to the generator automatically if the grid fails, and fall back to battery inverter mode if neither AC source is available. The transfer time is fast enough that most connected equipment will not notice the transition.
At 10kVA and 48V, this unit is intended for installations with substantial load requirements. The 140A charger can recharge a large battery bank quickly when AC is available, and the PowerAssist function means a smaller generator can be used without risk of tripping on peak loads. The VE.Bus interface is central to scalability: units can be wired in parallel for increased current capacity, or configured in split-phase or three-phase arrangements. Integration with Victron Cerbo GX or other GX devices gives full system monitoring and control via the VRM portal.
At 51kg, installation requires two people and appropriate mounting provisions. The unit is designed for fixed installation in a ventilated enclosure or dedicated plant room rather than portable use.

Installation Notes
This unit operates at 48V DC and 230V AC with a 140A charge current capability. Installation must be carried out by a qualified electrician or accredited installer. For any grid-connected application in the UK, compliance with G98 or G99 (depending on export capacity and DNO requirements) must be confirmed before commissioning. Generator connections should be sized and configured in accordance with the generator manufacturer's specifications and local wiring regulations. At 51kg, two-person lifting and secure fixed mounting are required. Adequate ventilation must be provided at the installation location.
