Victron Quattro-II - 12/3000 - 120-50/50 - 2X 120V

The Quattro-II - 12/3000 - 120-50/50 - 2X 120V is a versatile and robust inverter/charger tailored for marine and boating applications. Designed to handle standard North American 50A 120/240VAC split-phase systems, it ensures reliable power management on board, seamlessly integrating with multiple power sources to keep your vessel's systems running smoothly.

Advanced Power Management for Your Vessel

The Quattro-II combines an efficient inverter and a powerful charger, enabling it to manage your boat’s electrical needs with precision. Whether you’re docked or cruising, it ensures a stable power supply, protecting your sensitive electronics and heavy-duty appliances alike.

Flexible AC Input and Output Options

The Quattro-II supports dual AC inputs, allowing connections from both a split-phase 120/240V source and a single-phase 120V source. This flexibility ensures continuous power supply by automatically switching to the active source, mirroring the input to the output to maintain consistent voltage for your onboard systems.

Reliable Inverter Mode

When external AC sources are unavailable, the Quattro-II switches to inverter mode, providing a steadfast 120V single-phase output. This ensures that essential 120V loads remain powered, while 240V loads are only active when a split-phase source is present, safeguarding your battery from high-demand appliances like water heaters and air conditioners.

Enhanced Features for Optimal Performance

PowerControl and PowerAssist

Optimize the performance of your grid or generator with PowerControl and PowerAssist. Set a maximum current limit to prevent overloading your power sources. PowerControl intelligently manages battery charging using available excess power, while PowerAssist supplements peak power demands with battery energy, ensuring smooth operation without stressing your primary power sources.

Dual AC Inputs and Outputs

The ability to connect two independent AC sources, such as shore power and a generator, provides unparalleled flexibility. The Quattro-II automatically switches to the active source, maintaining uninterrupted power to your 120V loads with a transfer time of less than 18 milliseconds for L1, ensuring sensitive electronics remain operational without disruption.

Scalable Power with Parallel and Three-Phase Operation

Expand your power system by connecting up to six Quattro-II units in parallel for increased output. Additionally, configure three units for three-phase power, ideal for larger vessels requiring balanced power distribution. In multi-phase setups, L2 is disabled across all units to maintain system integrity.

Comprehensive System Monitoring and Control

On-Site Configuration

Configure and monitor your Quattro-II effortlessly using the VictronConnect app or VEConfigure software. Easily adjust settings and access system information through various interfaces including Cerbo GX, Color Control GX, laptops, Bluetooth, Battery Monitors, and Digital Multi Control Panels.

Remote Management

Stay connected to your power system no matter where you are. With a Cerbo GX or compatible GX product, you can access the Victron Remote Management (VRM) platform to monitor and adjust settings online, ensuring your vessel’s power system is always optimized.
