Victron Energy MultiPlus-II 12/3000 Inverter Charger with PowerAssist and UPS Function

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 is a versatile hybrid inverter charger designed for reliable power management in various applications. Combining the functionalities of the MultiPlus and MultiGrid, this model offers advanced features such as external current sensing for PowerControl and PowerAssist, enabling it to optimize self-consumption and prevent overloads when connected to limited AC sources like generators or shore power. Its built-in anti-islanding and extensive country approvals make it suitable for global use, ensuring compliance and safety across different regions. The PowerAssist feature is particularly valuable, as it automatically reduces battery charging during overload conditions and boosts power output from the battery to support connected loads, providing a seamless power experience even under demanding circumstances. The inverter's role within an Energy Storage System (ESS) setup is critical, especially when integrated with MPPT Solar Chargers or Grid-tie PV Inverters, offering flexible and scalable energy solutions tailored to your needs. In the event of a grid failure or disconnection from shore or generator power, the MultiPlus-II's uninterrupted power supply (UPS) function activates instantly, switching to inverter mode in less than 20 milliseconds to ensure continuous operation of sensitive electronics and computers. Remote monitoring and control are facilitated through compatibility with Victron's GX devices, such as the Cerbo GX, allowing users to oversee and manage their systems remotely via the VRM app or portal. This comprehensive control extends from system adjustments to automated backup generator start-ups, enhancing operational efficiency and convenience. Designed with robust features and extensive approvals, the Victron MultiPlus-II 12/3000 is an ideal choice for dependable, intelligent power management in residential, commercial, or off-grid setups. For detailed installation and operation instructions, refer to the official owners manual available online.
