Description
xVictron Quattro 48/8000/110-100/100 230V VE.Bus Inverter Charger
The Victron Quattro 48/8000/110-100/100 is a 8000VA inverter charger designed for demanding off-grid, backup and hybrid power installations. It accepts two independent AC inputs, making it suitable for systems where both shore power and a generator are present. Built around a 48V battery bank, it is aimed at professional installers working on residential, commercial and marine applications.
Key Features
- 8000VA continuous inverter output at 230V AC, with a 48V DC battery input range.
- Dual AC input connections allow simultaneous connection of mains grid and a generator, with automatic transfer switching between them.
- 110A battery charger built in, with adaptive charging algorithm that adjusts to battery condition and type.
- Two 100A AC outputs: AC-Out-1 remains live during mains failure; AC-Out-2 disconnects when running on inverter, allowing non-essential loads to be shed automatically.
- VE.Bus communication interface enables parallel and three-phase configuration with multiple Quattro units, and full integration with Victron GX devices and Venus OS.
- PowerControl and PowerAssist functions prevent generator or shore power overload by limiting charger current draw and supplementing AC supply with battery power when demand spikes.
- Compatible with a wide range of battery chemistries including lead-acid (flooded, gel, AGM) and lithium, with configurable charge profiles.
Product Overview
The Quattro range sits above the MultiPlus in Victron's inverter charger lineup by virtue of its dual AC input. Where a MultiPlus accepts one AC source, the Quattro manages two independently, switching between them based on availability and priority. In practice, this means a generator can be wired as a secondary source and will only be engaged when mains power is absent, without any manual intervention or external changeover switch.
The 110A charger is substantial for an 8kVA unit and allows a large 48V battery bank to be recharged at a meaningful rate from either AC source. PowerAssist is particularly useful in generator-backed systems: when a load spike would otherwise overload the generator, the Quattro draws the shortfall from the battery bank rather than tripping the generator's breaker. This allows a smaller, more fuel-efficient generator to be used without risk of overload.
VE.Bus connectivity is central to the Quattro's scalability. Up to six units can be configured in parallel for higher power output, or arranged in split-phase or three-phase configurations. Integration with Victron Cerbo GX or other GX devices provides full system monitoring, remote configuration via VRM, and ESS (Energy Storage System) functionality for grid-tied battery storage applications.

Applications
- Off-grid residential and commercial installations requiring high continuous power output with generator backup.
- Marine and yacht installations where both shore power and a generator must be managed automatically.
- Critical backup power systems where AC-Out-2 load shedding is used to protect essential circuits during a mains outage.
- Scalable three-phase or parallel systems built from multiple Quattro units via VE.Bus.
- ESS (Energy Storage System) installations integrated with a Victron GX device for grid-tied battery storage and self-consumption optimisation.
- Remote and rural sites with unreliable grid supply, where generator runtime needs to be minimised using PowerAssist.

Installation Notes
The Quattro 48/8000/110-100/100 operates at high DC currents from a 48V battery bank and connects to 230V AC mains supply. Installation must be carried out by a qualified electrician or MCS-accredited installer. In the UK, any grid-connected or grid-parallel configuration must comply with G98 or G99 requirements as applicable, and may require prior notification to or approval from the Distribution Network Operator (DNO). Battery connections, cable sizing and fusing must be specified in accordance with the system design and relevant wiring regulations. Configuration of charge profiles, VE.Bus networking and ESS settings should be performed using Victron's VictronConnect or VEConfigure software by a competent person familiar with Victron systems.
