Overview Sizing Benefits Like the MultiPlus, the Quattro is an all-in-one inverter and battery charger, with an internal transfer switch. While the Multiplus has a single AC input, the Quattro has two independent AC inputs, allowing direct connection of both shore and generator power. Quattro inverter/chargers are Victron’s most flexible units and can be configured into a variety of systems, including traditional DC-coupled solar, hybrid systems, and ESS applications for AC-coupled solar. Victron inverter/chargers are compatible with lithium, lead acid, and AGM battery chemistries. Change settings in minutes using VE.Configure software on a laptop with an MK3-USB interface. The Quattro line embodies Victron’s modular approach to power system components. The Quattro is available in 12V, 24V, and 48VDC with models ranging from 3000VA to 15000VA These powerful units can provide single-phase power with a single unit, 120V/240V split-phase power with a pair of units, and even 3-phase power for more complex systems. You may also stack them in parallel for even more power. Up to 6 Quattro 48/5000 inverter/chargers can be stacked in parallel per phase providing a high degree of scalability for large power requirements. The Victron naming convention explains the system's potential based on its design.

Check out the Victron Energy Inverter/Charger Buyer Checklist. Several stand-out features make Victron's Quattro ideal for large-scale power systems, including: High power handling makes the Quattro suitable for larger homes, businesses, or industrial operations. Dual AC input flexibility allows simultaneous connection to two power sources (e.g., grid and generator), optimizing power availability. Seamless transfer between power sources ensures no interruptions in critical systems, especially in backup power applications. Advanced battery charging with profiles for LiFePO4 batteries maximizes battery health and performance. Three-phase support and parallel connections allow for scalability, making the Quattro a robust solution for large installations. Remote monitoring and control via Bluetooth or VRM using a Victron GX device for convenient system management and troubleshooting. PowerAssist technology helps prevent overloading and enhances the overall efficiency of the system.
