Victron Energy MultiPlus-II 12/3000 - 120-50 - 2x 120V UL Approved Power Inverter and Charger

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

The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid. 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 the 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 occurs. The second level will boost the output of a generator or shoreside supply with power taken from the battery.

ESS: Energy Storage Systems

The MultiPlus-II is the critical component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters. For examples and more detailed information see the ESS (Energy Storage System) manual.

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 backup generator and more.

The Victron Energy MultiPlus-II 12/3000 (Part Number PMP122305102) is a versatile power management system designed for seamless integration into energy storage and power backup setups. Combining the functions of a high-capacity inverter, charger, and power management device, the MultiPlus-II provides reliable power conversion and system control for a variety of applications. Its robust design and UL approval ensure safe operation in multiple countries, making it an excellent choice for residential, commercial, and off-grid energy solutions. The unit features a built-in anti-islanding protection, ensuring safe operation during grid disturbances, and supports external current sensing for advanced PowerControl and PowerAssist functions, optimizing energy use in systems with limited AC sources.

PowerAssist functionality allows the MultiPlus-II to prevent overloads from limited AC sources such as generators or shore power connections by reducing battery charging during overload conditions and boosting output from the battery when necessary, ensuring continuous power delivery. Its role as a critical component in Energy Storage Systems (ESS) makes it compatible with MPPT solar chargers and grid-tie PV inverters, providing flexible energy management options. In the event of grid failure or disconnection from shore or generator power, the MultiPlus-II's inverter automatically switches to UPS mode within less than 20 milliseconds, maintaining uninterrupted power to connected loads including sensitive electronic equipment.

Remote monitoring and control are facilitated through compatibility with Victron's GX devices such as the Cerbo GX. Users can monitor and manage their system locally or remotely via the VRM app or portal, accessible from smartphones, tablets, laptops, or PCs. This connectivity allows for detailed system adjustments, auto-start functions for backup generators, and comprehensive system oversight from anywhere in the world. The Victron MultiPlus-II is a reliable, intelligent solution for managing complex energy systems, ensuring power stability and optimal energy use.
