Victron Quattro Inverter Charger (12V / 3000VA / 120A)

The Victron Quattro 12/3000/120-50/50 is a powerful inverter charger that combines a pure sine wave inverter, high-capacity 120A battery charger, and dual AC transfer switches into one advanced power management solution. Designed for marine, motorhome, off-grid, backup power, and commercial energy applications, it offers exceptional flexibility by allowing connection to two independent AC power sources, such as shore power and a generator, with automatic source selection.

Delivering 3000VA of inverter power and a powerful 120A charging output, the Quattro provides reliable mains-quality AC power while ensuring rapid battery charging. Its advanced PowerAssist technology prevents generator or shore power overload by supplementing available AC power with energy from the battery bank during periods of high demand.

The integrated transfer system provides uninterrupted power with a switchover time of less than 20 milliseconds, making it ideal for sensitive electronics, communications equipment, and critical loads. The Quattro can also be configured for parallel, split-phase, or three-phase operation, allowing systems to expand as power requirements grow.

Technical Specifications

Advanced Features

Dual AC Inputs with Automatic Switching

The Quattro can be connected to two separate AC sources simultaneously, such as a generator and shore power connection. It automatically selects the active source and seamlessly transfers between them when required.

Dual AC Outputs

• Main Output: Provides uninterrupted inverter-backed power.
• Secondary Output: Active only when an AC source is available, ideal for high-consumption loads such as water heaters or air conditioning units.

PowerAssist Technology

Automatically supplements limited shore or generator power with battery power during peak demand periods, preventing overloads and maximising available energy.

UPS Functionality

Switches to inverter operation in less than 20 milliseconds during power interruptions, ensuring uninterrupted operation of computers, communication systems, and other sensitive equipment.

Expandable System Design

Multiple Quattro units can be connected in parallel to increase output power. The system also supports split-phase and three-phase configurations for larger installations.
