Like the MultiPlus, the Victron Quattro 48/10000/140-100/100 120V is a combined inverter and charger, but it adds a second AC input. It connects automatically to whichever source is active, such as shore power and a generator, and carries a UL listing.

Suited to large 48V homes, off-grid properties, and vessels that combine grid or shore power with a backup generator.
Victron Quattro 48/10000/140-100/100 120V Inverter/Charger (UL Listed) Similar to the MultiPlus, the Quattro is also a combined inverter and charger. Additionally it can accept two AC inputs and automatically connect to the active source. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology plus multiple system integration features such as three or split phase operation and parallel operation. Key Features: Combined Inverter & Charger Similar to the MultiPlus, the Quattro integrates both an inverter and a charger. Accepts two AC inputs and automatically connects to the active power source. Two AC Inputs & Two AC Outputs Automatically switches to the active source. Connects to two independent AC sources (e.g., shore power & generator). Main Output: No-break functionality—ensures uninterrupted power during grid failure or power disconnection. Second Output: Activates only when AC is available, ideal for non-battery-dependent loads like air conditioning or water heaters. PowerAssist Technology Prevents overload of a limited AC source (e.g., generator or shore power). Dynamically reduces battery charging to prevent overload. Boosts output using battery power when needed. High Power Scalability Supports parallel operation—connect up to 6 Quattros for increased power output. Compatible with three-phase and split-phase setups (refer to datasheets for model-specific capabilities). Remote Monitoring & Control Works with a GX device (e.g., Cerbo GX) for local (LAN) and remote monitoring. Free VRM app & portal for real-time system control from anywhere. Access via phone, tablet, laptop, or PC to adjust settings, start backup generators, and more.
