Victron Energy MultiPlus-II Pure Sine Wave Inverter Charger – 12V, 3000VA, 120A, 120V

Overview

The Victron Energy MultiPlus-II Pure Sine Wave Inverter Charger is a versatile power hub that blends the capabilities of the MultiPlus and MultiGrid into one unit. It delivers clean, reliable sine-wave power for sensitive devices while offering smart control options and flexible installation choices. With an external current transformer option, you can implement PowerControl and PowerAssist, helping you tailor energy use to your setup and maximize self-consumption when paired with other sources of generation.

Power Control and Efficiency

Designed for smarter energy management, the MultiPlus-II supports an external current transformer (up to 32 A) to enable PowerControl and PowerAssist. This setup helps balance loads and optimize how energy is drawn from available sources, making it a compelling choice for blends of solar, generator, or shore power.

• PowerControl enables smarter energy balancing with external sensing and feedback.
• PowerAssist helps prevent overloads when a limited AC source is in use, such as a small generator or limited shore power.

Uninterrupted Power for Demanding Loads

In the event of grid failure or when shore or generator power is disconnected, the MultiPlus-II switches to inverter power within about 20 milliseconds. The quick handover helps keep essential systems running with minimal interruption.

Scalable and Flexible Installations

For larger setups, you can parallel up to six MultiPlus-II units to achieve higher output. Additionally, three units can be configured to deliver a three-phase output, expanding the range of off-grid and shore-independent scenarios you can support.

• Paralleling up to 6 units increases total available power.
• Three-phase configuration is possible with multiple units for balanced loads.

Why Professionals Choose MultiPlus-II

Professionals rely on this inverter charger for marine, yacht, vehicle, and land-based off-grid applications due to its robust feature set and broad compatibility. It includes built-in anti-islanding and a growing list of country approvals, supporting safe and compliant operation in many regions.

Key Features in Practice

• Pure sine wave output suitable for sensitive electronics and appliances
