Introducing the Victron Quattro-II, a 12V battery-powered, 3000 VA inverter/charger designed for North American 50A 120/240 VAC split-phase systems. With dual AC inputs, automatic source selection, and two mirrored 120V outputs, it powers essential loads reliably in homes, boats, RVs, and off-grid sites.
-
Dual AC inputs with automatic source selection: Automatically connect to the active shore power or generator for seamless, hands-off power management.
-
Two AC outputs with mirrored behavior: Outputs mirror the live input when one source is active, ensuring consistent distribution across connected loads.
-
120/240V input and output compatibility: Supports 120V and 240V operation; in inverter mode, the unit provides 120V output on both L1 and L2; 240V loads require a split-phase source.
-
Inverter takeover with no-break transfer: When AC is unavailable, the inverter seamlessly takes over to maintain power continuity.
-
No-break transfer timings: Main output switches to inverter or alternate source in under 18 milliseconds; auxiliary output transitions in about 40 milliseconds.
-
PowerControl: Set a maximum grid or generator current; the unit uses any spare 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 demand and automatically recharges 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; L2 disables in multi-phase configurations.
-
No-break main output: The primary output remains uninterrupted during source changes, keeping essential devices powered.
-
Reliable, scalable design for real-world use: Built to support homes, boats, RVs, or work sites needing intelligent power management and high availability, with growth-ready configurations from single-unit setups to larger multi-unit systems.
With the Victron Quattro-II, you gain a versatile power backbone that protects sensitive electronics, supports essential loads during outages, and scales as your power needs grow. The dual inputs let you harvest shore power or generator energy without manual switching, while the mirrored outputs simplify wiring and distribution. PowerControl and PowerAssist optimize capacity without tripping breakers, and no-break transfer ensures critical devices stay online during transitions. Whether you’re safeguarding a fridge during an outage, powering a mobile home or boat, or expanding toward a larger off-grid system, the Quattro-II delivers dependable, adaptable power without compromise.
