xVictron Quattro-II 24/5000/120-50/50 230V Inverter Charger — QUA242505010
The Victron Quattro-II 24/5000/120-50/50 is a 5000VA inverter charger designed for 24V battery systems operating at 230V AC. It accepts two independent AC inputs, making it suited to installations where both a generator and a shore or grid supply need to be managed automatically. This unit is aimed at professional installers working on off-grid, marine, vehicle and backup power systems.
Key Features
- 5000VA continuous inverter output at 230V AC from a 24V DC battery bank.
- 120A multi-stage battery charger built in, supporting bulk, absorption and float charging.
- Two independent AC inputs (50A each) with automatic transfer switching between grid and generator supplies.
- PowerControl and PowerAssist functions limit the load on the AC input and supplement it with battery power when demand exceeds the available supply.
- Compatible with Victron VE.Bus communication for system integration, remote monitoring and parallel or three-phase configuration.
- Supports parallel operation (up to six units) and split-phase or three-phase setups for larger installations.
- Programmable relay outputs and configurable charge parameters via VEConfigure software.
Product Overview
The Quattro-II replaces the original Quattro range and shares the same core architecture while offering updated internal components. The dual AC input is one of its defining characteristics: the unit monitors both inputs and switches automatically to whichever is available, with no break in output. This is particularly useful on sites where a generator is the backup to a grid connection, or on vessels where shore power and a generator are both present.
The 120A charger is sized to handle large battery banks typical of 24V off-grid and backup installations. Charge parameters are fully adjustable, and the unit supports lithium battery profiles alongside lead-acid chemistries. PowerAssist allows the inverter to supplement an undersized AC supply rather than trip it, which is valuable when a generator or shore connection has a lower current rating than the connected loads demand.
VE.Bus connectivity enables the Quattro-II to be integrated into a Victron system alongside MPPT solar charge controllers, a Cerbo GX monitoring unit and other VE.Bus devices. Multiple units can be configured in parallel to increase output capacity, or in three-phase arrangements for commercial and industrial applications.

Installation Notes
The Quattro-II must be installed by a qualified electrician familiar with inverter charger systems. At 31 kg, two-person handling is advisable during mounting. DC cabling must be rated for the high currents involved in a 24V/5000VA system and kept as short as practicable to minimise voltage drop. Battery connections must be fused appropriately. For any grid-connected or generator-connected installation in the UK, compliance with current wiring regulations (BS 7671) and relevant network operator requirements is the installer's responsibility. Lithium battery installations require correct charge profile configuration via VEConfigure before commissioning.
