Inverter/Charger with Dual AC Inputs for Marine, Off-Grid and Backup Power Systems

The Victron Quattro 24/3000/70-50/50 230V VE.Bus combines inverter, battery charging and automatic transfer functionality for marine, off-grid, backup and energy storage applications. Two independent AC inputs allow connection to sources such as shore power, the electricity grid or a generator, with automatic selection of the active source. PowerControl manages available incoming power to prevent the AC supply from being overloaded, while PowerAssist supplements a limited AC source with battery power when demand increases. VE.Bus connectivity supports system integration, remote monitoring and configuration, including parallel and three-phase installations.

Key Features

• Dual AC Inputs: Connects to two independent AC sources and automatically transfers to the active supply.
• Dual AC Outputs: Maintains uninterrupted power to essential loads through the main output, while the auxiliary output operates only when an external AC source is available.
• No-Break Transfer: Automatically takes over connected loads during an AC supply interruption to maintain operation of sensitive electronic equipment.
• PowerControl: Manages available shore, generator or grid power and allocates remaining capacity to battery charging.
• PowerAssist: Supplements limited incoming AC power with energy from the battery when connected loads exceed the available supply.
• VE.Bus Communication: Supports system integration, remote monitoring, parallel operation and three-phase configurations.
• Parallel and Three-Phase Capability: Multiple compatible units can be configured to increase system capacity or provide three-phase output.
• Lithium Battery Compatible: Supports integration into compatible lithium battery systems.
• Solar and Off-Grid Integration: Suitable for grid-connected and off-grid renewable energy systems incorporating compatible solar equipment.
• Remote Monitoring: Compatible with Cerbo GX and other GX devices for system monitoring and access through the VRM platform.
• Remote Configuration: Compatible GX-connected systems can be accessed and configured remotely when connected to the internet.
• Integrated Protection: Protects against short circuit, overload, excessive or insufficient battery voltage, excessive temperature, AC voltage on the inverter output and excessive input voltage ripple.

Facilitating management of multiple AC sources and battery power within a single system, the Quattro supports installations where continuity and intelligent power allocation are important. Its VE.Bus integration, PowerControl and PowerAssist functions allow the inverter/charger to operate as part of scalable standalone, backup and renewable energy systems.
