Victron Energy MultiPlus-II 48/5000 70-95 120V UPS Inverter/Charger with PowerControl and Energy Storage System Integration

MultiPlus-II 48/5000 70-95 120V (UL1741)

The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid.

Evolved Inverter/Charger

It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A). It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.

PowerAssist

The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.

ESS: Energy Storage Systems

The robust MultiPlus-II is the key component in a Victron Energy Storage System. Our new Dynamic ESS feature takes ESS to the next level. It automatically switches between - or combines - grid, battery and solar energy based on live-pricing, predicted energy-use and solar yield so its always consuming the cheapest energy.

Uninterrupted AC Power (UPS Function)

In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.

Remote Monitoring Control

When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto starting a backupgenerator and more

The Victron Energy MultiPlus-II 48/5000 70-95 120V (UL1741) is a versatile, high-performance inverter and charger designed to meet the demands of modern energy systems. Combining the functions of a MultiPlus and a MultiGrid, this unit offers advanced features such as PowerControl and PowerAssist, enabling it to prevent overloads when connected to limited AC sources like generators or shore power. It automatically reduces battery charging during overload conditions and boosts power output when needed, ensuring reliable operation in off-grid or backup scenarios.
Built with robust construction and certified for multiple countries, the MultiPlus-II is an essential component for energy storage systems. Its Dynamic Energy Storage System (ESS) intelligently switches between grid, battery, and solar energy, optimizing consumption based on live energy pricing, predicted usage, and solar yield. This dynamic management helps reduce energy costs while maximizing renewable utilization.
Additionally, the MultiPlus-II offers seamless uninterruptible power supply (UPS) functionality. In the event of a grid failure, it instantly switches to inverter mode in less than 20 milliseconds, providing continuous power to critical loads such as computers and medical equipment. This rapid transfer protects sensitive electronics from disruption or damage.
Remote monitoring and control capabilities are integrated through compatibility with Victron GX devices like the Cerbo GX. Users can access real-time system data and manage operations remotely via the free VRM app and portal, from any device connected to the internet. This level of control allows for remote system adjustments, auto-starting backup generators, and more, providing peace of mind and operational flexibility.
Designed for ease of integration, the MultiPlus-II is ideal for residential, commercial, and off-grid applications, offering reliable power management with cutting-edge technology. For detailed installation instructions or support, refer to the owner’s manual available online. Whether used as a standalone solution or part of a larger energy system, this inverter/charger delivers robust performance combined with intelligent energy management features.
