xVictron Quattro 48/5000/70-100/100 230V VE.Bus Inverter Charger — QUA485021010
The Victron Quattro 48/5000/70-100/100 is a 5000VA inverter charger designed for demanding off-grid, backup and hybrid power installations. It accepts two AC inputs simultaneously, making it suited to systems where both shore power and a generator are present. At 48V DC input with dual 100A AC outputs, it is built for professional installations where load management and source switching are critical.
Key Features
- 5000VA continuous inverter output at 230V AC, suitable for high-demand loads in off-grid and backup systems.
- Dual AC inputs allow simultaneous connection of shore power and a generator, with automatic source switching.
- 70A battery charger built in, with adaptive charge management to suit different battery chemistries and states of charge.
- Two independent 100A AC outputs: one with pass-through on both AC inputs, one that disconnects during inverter operation for non-critical loads.
- VE.Bus communication interface enables multi-unit parallel and three-phase configurations, as well as integration with Victron GX devices and Venus OS.
- PowerControl and PowerAssist functions limit generator or shore power draw and supplement from the battery when demand exceeds the available AC input.
- Compatible with a wide range of 48V battery chemistries including lead-acid, lithium and gel, 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 capability. Where a MultiPlus accepts one AC source, the Quattro accepts two, switching between them automatically based on availability and priority. This makes it particularly well suited to installations where a generator acts as a backup to shore power, or where two separate grid connections are available. The transfer switch is fast enough to prevent most sensitive equipment from losing power during the changeover.
The 70A charger is not a fixed-rate unit. It uses Victron's adaptive charge algorithm, which monitors battery behaviour over time and adjusts the charge profile accordingly. This is relevant in installations where the battery bank is regularly cycled, as it reduces the risk of under or overcharging. The PowerAssist function is equally practical: if the connected AC source reaches its current limit, the Quattro draws the balance from the battery rather than tripping the supply. This allows a smaller generator or limited shore power connection to run loads that would otherwise exceed its rating.
VE.Bus connectivity means the unit can be configured, monitored and updated via Victron's VictronConnect software and GX device ecosystem. Multiple Quattro units can be wired in parallel for increased output current, or configured in split or three-phase arrangements. This scalability makes the 48/5000 a practical choice for larger residential off-grid systems, marine vessels, vehicle conversions and commercial backup installations.

Installation Notes
The Quattro 48/5000 operates at 48V DC and handles significant current at the battery terminals. Installation must be carried out by a qualified electrician or accredited installer. In the UK, any grid-connected or generator-connected AC wiring must comply with BS 7671 (18th Edition). For systems connected to the public grid, G98 or G99 notification or approval may be required depending on system configuration. Use of a Victron GX device is strongly recommended for full system monitoring and configuration. Ensure battery cabling is rated for the maximum charge and discharge currents involved.
