Victron MultiPlus-II 12/3000 - 120-50 - 2x 120V UL Approved

The MultiPlus-II 12/3000 is a versatile and powerful inverter/charger designed specifically for marine applications. Combining advanced features from the MultiPlus and MultiGrid series, it ensures reliable and efficient power management on your vessel, seamlessly integrating with your boat's electrical systems.

Key Features

Integrated Inverter/Charger

The MultiPlus-II 12/3000 serves as both an inverter and a charger, providing seamless power conversion and management for your marine setup. Whether you're docked or underway, enjoy uninterrupted power supply and optimized battery charging.

PowerAssist

Designed to protect your boat's AC sources from overload, PowerAssist intelligently manages power usage. When connected to a limited AC source like a generator or shore power, the MultiPlus-II:

• Automatically reduces battery charging to prevent overload.
• Boosts the output by drawing power from the battery, ensuring smooth operation of your electrical systems.

This dual-level protection ensures that your onboard power sources remain safe and efficient, even under high-demand conditions.

Energy Storage Systems (ESS)

The MultiPlus-II plays a crucial role in a marine Energy Storage System (ESS). It seamlessly integrates with MPPT solar chargers and grid-tie PV inverters, allowing you to maximize energy self-consumption and optimize power usage onboard.

For detailed configurations and examples, refer to the ESS Manual.

Uninterrupted AC Power (UPS Function)

Stay powered during grid failures or when shore and generator power are unavailable. The MultiPlus-II's built-in UPS function activates the inverter in under 20 milliseconds, ensuring that your critical marine electronics and systems continue to operate without interruption.

Remote Monitoring & Control

Enhance your power management with remote monitoring and control capabilities. When paired with a GX device such as the Cerbo GX, you can:

• Monitor your MultiPlus-II and entire power system locally or remotely via the internet.
• Use the free VRM app or VRM portal website to access your system from any device, including phones, tablets, and laptops.
• Control various functions, such as adjusting settings or auto-starting a backup generator, from anywhere in the world.

This comprehensive control ensures that your marine power system is always optimized and accessible.
