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

The MultiPlus-II is a high-performance inverter/charger designed specifically for marine and boating applications. Combining the advanced features of the MultiPlus and MultiGrid, it offers unparalleled power management, reliability, and flexibility to keep your vessel's electrical systems running smoothly.

Advanced Power Management

The MultiPlus-II integrates the functionalities of both the MultiPlus and MultiGrid, providing comprehensive power control and optimization. With the addition of an external current transformer option, it enables PowerControl and PowerAssist, allowing you to maximize self-consumption and efficiently manage power from various sources.

PowerAssist

PowerAssist ensures that your vessel's limited AC sources, such as generators or shore power connections, are protected from overloads. It intelligently reduces battery charging to prevent overload and can boost the output of your generator or shore supply by drawing power from the battery when necessary.

Energy Storage Systems (ESS)

The MultiPlus-II serves as the cornerstone of a Victron Energy Storage System (ESS), offering seamless integration with MPPT solar chargers and grid-tie PV inverters. This flexibility allows you to create a robust and efficient energy system tailored to your boat's specific needs.

Uninterrupted AC Power (UPS Function)

Experience uninterrupted power supply with the built-in UPS function of the MultiPlus-II. In the event of a grid failure or when shore or generator power is disconnected, the inverter activates automatically within 20 milliseconds, ensuring that sensitive electronics and essential systems remain operational without interruption.

Remote Monitoring and Control

Stay connected and in control with the MultiPlus-II's remote monitoring capabilities. When paired with a GX device, such as the Cerbo GX, you can monitor and manage your system locally via LAN or remotely through the VRM app and VRM portal website. Access real-time data and control your inverter from anywhere in the world using your phone, tablet, laptop, or PC.
