Victron 3000VA MultiPlus-II 2X Pure Sine Wave Inverter Charger 120/240V Split Phase, 12-Volt

MultiPlus-II 2x 120V: The Ultimate Mobile Solution

The MultiPlus-II 2x120V is a robust, one-box solution tailored for North American 50A 120/240VAC split-phase applications. It seamlessly manages shore power, generators, and inverter operations, offering unmatched flexibility for mobile or off-grid power systems.

• Victron Energy Pure Sine Wave Inverter: The MultiPlus-II inverter charger combines the functions of the MultiPlus and the MultiGrid. It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A). It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.
• Power Assist: With the unique Power Assist feature, the MultiPlus-II solar inverter will prevent overload of a limited AC source, such as a generator or shore power connection.
• Power Without Interruption: In the event of a grid failure, or when shore or generator power is disconnected, the Victron inverter is activated fast, within 20ms, and takes over the supply to the connected loads.
• Parallel Operation: Up to 6 Victron Energy MultiPlus-II Pure Sine Wave Inverter units can operate in parallel to achieve higher power output. In addition to parallel connection, three units can be configured for three-phase output.
• Professional Inverter Charger: The MultiPlus-II is ideally suited for professional marine, yachting, vehicle, and land-based off-grid applications.

Features

• Split-Phase and Single-Phase Functionality:
  • Accepts and passes through both lines of a 120/240V supply to deliver the full 50A capacity for charging and AC loads.
  • Supports single-phase 120V supply by combining L1 and L2 outputs for balanced 120V power on both lines.
• Inverter Mode:
  • Automatically switches to inverter operation when no AC source is available.
  • Provides 120V single-phase power by internally connecting L1 and L2 outputs.
  • Supplies power to both sides of the distribution panel under all configurations, except for 240VAC, which requires a 120/240VAC split-phase source.
• Battery Protection:
  • Prevents high-demand 240V loads (e.g., water heaters or air conditioners) from discharging the battery when operating in inverter mode.
• Advanced Features:
  • PowerControl and PowerAssist for managing external power sources and avoiding overload.
  • Input Current Limit for protecting the system during peak demands.
  • Dual AC Outputs to prioritize critical loads.
  • Parallel and 3-phase configuration compatibility for scalable VE.Bus systems.
  • Compatible with LiFePO4 and other battery technologies.

Applications

• Ideal for RV, marine, and off-grid systems where 120/240VAC split-phase power is required.
• Perfect for environments with mixed shore power, generator, or solar inputs.

The MultiPlus-II 2x120V combines versatility, reliability, and efficiency, ensuring your power system is ready for any challenge.
