Victron Energy MultiPlus-II 3000VA 48V Pure Sine Wave Inverter Charger | PowerAssist | UL Certified

The Victron Energy MultiPlus-II is a compact, rugged all-in-one power solution that merges a pure sine wave inverter, a smart battery charger, and a versatile transfer switch into a single, tidy enclosure. By integrating these functions, it simplifies wiring and reduces component count while delivering dependable performance in a wide range of environments. For systems that include solar, the unit can be configured with an external current transformer to enable PowerControl and PowerAssist, which help optimize self-consumption and respond dynamically to available power. Built to meet demanding installation standards, it carries UL certification and broad country approvals to support global use.

Key benefits at a glance

• Pure sine wave inverter output protects sensitive electronics and appliances
• Integrated inverter, charger, and transfer switch for a streamlined setup
• PowerAssist to prevent overload on limited AC sources such as shore power or generators
• PowerControl via external current sensing (max 32A) to optimize self-consumption
• Built-in anti-islanding and wide country approvals for safe operation

Backup power and fast handoff

In the event of grid failure or when shore power disconnects, the MultiPlus-II switches to battery power quickly, delivering uninterrupted power to connected loads within about 20 milliseconds. This fast transition helps preserve lighting, electronics, and essential devices without noticeable interruption.

• Parallel operation up to six units to achieve higher output
• Three units can be configured for a three-phase system when required
• Professional-grade design suited for marine, yacht, vehicle, and off-grid installations

Flexibility and system compatibility

The 3000 VA, 48-volt configuration provides a robust backbone for off-grid and hybrid systems. An external current transformer option enables PowerControl and PowerAssist with sensing up to 32A, while UL certification and broad approvals simplify compliance across regions. This inverter charger is designed to integrate with other Victron components and solar controllers to maximize energy efficiency and reliability.

Real-world use scenarios

Whether you are outfitting a live-aboard boat, a remote cabin, or a mobile workshop, the MultiPlus-II offers a dependable power partner. Its compact footprint and modular expansion potential support evolving power needs without replacing the core hardware.
