Victron MultiPlus-II 48/3000 - 35-50 - 120V - UL Approved

The MultiPlus-II 48/3000 - 35-50 - 120V is a state-of-the-art inverter/charger designed specifically for marine and boating applications. Combining the robust features of the MultiPlus and MultiGrid, this UL-approved device ensures reliable power management and seamless energy integration on board your vessel.

Advanced Power Management

PowerAssist

The MultiPlus-II safeguards your boat’s electrical system by preventing overloads from limited AC sources such as generators or shore power connections. Should an overload situation arise, the MultiPlus-II intelligently reduces battery charging to maintain system stability. Additionally, it can boost the output from generators or shore supplies by drawing power from the battery, ensuring continuous and reliable power for all onboard systems.

Energy Storage Systems (ESS)

The MultiPlus-II serves as the cornerstone of a Victron Energy Storage System (ESS) on your boat. It offers unparalleled flexibility by seamlessly integrating with MPPT solar chargers or grid-tie PV inverters. This integration optimizes energy usage, enhances self-consumption, and ensures you have a dependable power supply even in the most demanding marine environments.

Uninterrupted AC Power (UPS Function)

Experience uninterrupted power during grid failures or when disconnecting from shore or generator power. The inverter within the MultiPlus-II activates automatically within 20 milliseconds, ensuring that sensitive electronics such as navigation systems and communication devices continue to operate without disruption. This ultra-fast transition is crucial for maintaining safety and functionality on board.

Remote Monitoring and Control

With the integration of a GX device, like the Cerbo GX, you can effortlessly monitor and control your MultiPlus-II and entire power system both locally and remotely. Access your system from anywhere in the world using the free VRM app or the VRM portal website. Whether you are on shore or navigating the open seas, you can adjust settings, monitor performance, and even auto-start a backup generator to ensure your vessel’s power needs are always met.
