Quattro-II 12/3000/120-50/50 2x120V

Victron Quattro-II 12/3000/120-50/50 – 2x120V Split-Phase Inverter/Charger (12V DC)

The Victron Quattro-II 12/3000/120-50/50 is a versatile 3kVA inverter/charger designed for 12V DC battery systems and North American split-phase 120/240V installations. With dual AC inputs, dual AC outputs, and advanced grid/generator compatibility, it’s ideal for off-grid, backup, or mobile applications where reliable and flexible power management is required.

Key Features:

• 3kVA Pure Sine Wave Inverter:
  Delivers clean 120V AC power from a 12V battery bank, supporting sensitive electronics and high-demand appliances.

• Split-Phase 2x120V Output:
  Configured to deliver 120/240V split-phase output—ideal for North American homes, RVs, and hybrid systems with both 120V and 240V loads.

• Dual AC Inputs – Grid + Generator:
  Automatically switches between two independent AC sources (e.g. grid and generator) with built-in transfer switching logic.

• 120A Battery Charger:
  Fast and adaptive multi-stage charger for lithium, AGM, GEL, and flooded batteries, ensuring optimal performance and longevity.

• 50A Transfer Switch per Input:
  Manages up to 50A from each AC input (grid and generator) for seamless, fast switching.

• PowerAssist Function:
  Temporarily boosts limited AC input (e.g. generator or shore power) by adding inverter output to prevent overloads.

• Remote Monitoring-Ready:
  Compatible with Victron Cerbo GX, GX Touch, and VRM Portal for remote access, configuration, and firmware updates.
