Victron Quattro 12V 5000W Inverter/Charger - Professional Marine & Off-Grid Power System

Dual-Input Inverter/Charger with PowerAssist Technology and Automatic Transfer Switch

The Victron Quattro QUA125021100 represents the pinnacle of marine and off-grid electrical systems, combining a powerful 5000W pure sine wave inverter, intelligent 200A battery charger, and sophisticated dual-input automatic transfer switch in a single robust unit. Engineered for demanding marine environments, RV applications, and off-grid installations, this professional-grade system delivers uninterrupted power with industry-leading reliability and advanced load management capabilities.

Revolutionary Dual AC Input Architecture

Unlike conventional inverter/chargers limited to single AC sources, the Quattro features two independent 100A AC inputs that can simultaneously connect to shore power and generator, two generators, or any combination of AC sources. The intelligent control system automatically prioritizes and switches between sources based on availability and user-defined preferences, ensuring optimal power utilization and seamless operation.

Intelligent Source Management

• Automatic Source Detection: Instantly recognizes and connects to available AC sources
• Priority-Based Switching: User-configurable source hierarchy ensures preferred power utilization
• Dual 100A Inputs: Each input rated for full 100A capacity with independent monitoring
• Voltage Range Tolerance: Accepts 94-140V AC input for maximum compatibility
• Frequency Adaptation: Automatically adjusts to 50Hz or 60Hz input frequency

Advanced PowerAssist Load Support Technology

The exclusive PowerAssist feature prevents AC source overload by intelligently supplementing available power with battery energy. When connected loads exceed the capacity of shore power or generator input, the Quattro seamlessly adds battery-powered assistance, allowing you to run high-demand appliances without tripping breakers or overloading limited AC sources.

Multi-Level Load Management

1. Charging Reduction: Automatically reduces battery charging current when input approaches capacity limits
2. Power Boost Mode: Supplements AC input with battery power during high-demand periods
3. Load Prioritization: Maintains critical loads while managing non-essential equipment
4. Seamless Operation: No interruption to connected equipment during power management

Ultra-Fast Transfer Switch Technology

The Quattro's main output features true uninterruptible power supply (UPS) functionality with transfer times under 20 milliseconds. This lightning-fast switching ensures computers, navigation electronics, and sensitive equipment continue operating without disruption during source changes, power outages, or generator starts.

Dual AC Output Configuration

• Main Output: Continuous power with no-break UPS functionality for critical loads
• Auxiliary Output: AC-only output for non-essential loads like air conditioning and water heaters
• Load Segregation: Prevents non-critical equipment from discharging batteries
• Automatic Switching: Auxiliary output automatically disconnects during inverter-only operation

Professional-Grade 5000W Pure Sine Wave Inverter

The Quattro delivers clean, stable 120V AC power with pure sine wave output identical to utility grid power. This high-quality waveform ensures optimal performance of sensitive electronics, efficient operation of motors and appliances, and elimination of interference with communication equipment.

Features:

• Two AC Inputs & two AC Outputs - The Quattro can be connected to two independent AC sources, for example shore-side power and a generator, or two generators. The Quattro will automatically connect to the active source. The main output has no-break functionality. In the event of a grid failure, or shore or generator power being disconnected, the Quattro takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on one of the inputs of the Quattro. Loads that should not discharge the battery, such as air-conditioning or a water heater can be connected to this output.
• Unique PowerAssist feature - The Quattro will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.
• Virtually unlimited power thanks to parallel operation -Up to 6 Multis can operate in parallel to achieve higher power output. Three phase or split phase operation is also possible. Please check our datasheets to see which models have paralleling, three phase and split phase capabilities.
• Remote Monitoring and Control - Monitor and control your MultiPlus and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, via the required Color Control GX or Venus GX, from adjusting your MultiPlus to setting a Geofence for hire vehicles and more...
