Quattro 12/5000/220-100/100 120V VE.Bus (UL 458) - QUA125021102

Overview

The Victron Quattro is a powerful and flexible inverter/charger designed for demanding energy systems that require multiple AC sources. Similar in concept to a combined inverter and charger, the Quattro adds the critical advantage of two AC inputs, automatically connecting to the active source—such as grid and generator, or dual generators.

With no-break functionality on the primary output, advanced PowerAssist capability, and scalable system configurations, the Quattro is ideally suited to residential, marine, commercial, and off-grid applications where reliability, flexibility, and uninterrupted power are essential.

Key Features

Two AC Inputs & Two AC Outputs

• Connects to two independent AC sources with automatic source selection
• Primary output provides uninterrupted power transfer (<20 ms)
• Secondary output is active only when AC input is available—ideal for non-essential loads

True Sine Wave Inverter & Charger

• High-quality true sine wave inverter for sensitive equipment
• Integrated battery charger with adaptive charging technology
• Designed for reliable continuous operation

Unique PowerAssist Functionality

• Prevents overload of limited AC sources such as generators or shore power
• Automatically reduces battery charging when overload risk is detected
• Boosts available AC power using battery energy when required

Scalable System Architecture

• Up to six Quattro units can operate in parallel
• Supports split-phase and three-phase system configurations
• Suitable for small to large-scale power installations

Remote Monitoring & Control

• Monitor and control locally or remotely when paired with a GX device (e.g. Cerbo GX)
• Access via the free VRM app or VRM portal from phone, tablet, or computer
• Advanced control options including system optimisation and generator automation
