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

Introducing the Victron Quattro-II - 12/3000 - 120-50/50 - 2X 120V, a high-performance combined inverter and charger designed for standard North American 50A 120/240VAC split-phase applications. With dual AC inputs and automatic source selection, it keeps essential power online by automatically connecting to the active source.

Smart, Flexible Power for Backup and Off-Grid Systems

The Quattro-II supports 120/240V input and output, or 120V input and output (Always 120V output when in inverter mode). The two AC inputs can be fed from a split-phase 120/240V source or a single-phase 120V source. When one input is live, the Quattro outputs mirror that input. Inverter operation takes over when no AC is available, delivering 120V single-phase power on both L1 and L2 (bridged) for loads on either line. 240V loads are only supplied when a split-phase source is present.

• Two AC inputs and two AC outputs: Automatically connect to the active source (shore power or generator) for seamless, no-fuss power management.
• No-break transfer: The main output (L1) switches to inverter or alternate source in under 18 milliseconds, while the auxiliary output (L2) transfers in about 40 milliseconds to keep electronics running.
• PowerControl: Set a maximum grid or generator current; the unit uses any extra capacity to charge the batteries, preventing overload of the power source.
• PowerAssist: When peak power is required, the Quattro borrows energy from the battery to meet the demand and recharges automatically when the load subsides.
• Parallel and three-phase operation: Scale up to six Quattros in parallel for higher power, or configure three units for a three-phase output. In multi-phase setups, L2 is disabled on all units.
• No-break main output: The primary output remains uninterrupted during source changes, ensuring critical devices stay powered.

Designed for reliability and scalability, the Quattro-II is ideal for homes, boats, RVs, or work sites needing intelligent power management, high availability, and the ability to expand as your power needs grow.
