Victron Energy MultiPlus-II 12/3000 – 120V Power Inverter and UPS System

MultiPlus-II 12/3000 - 120-50 - 120V

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 and 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 power solution designed to seamlessly combine inverter, charger, and power management functions in one compact unit. This model is ideal for off-grid, backup power, and energy storage applications, offering reliable performance with integrated features such as PowerAssist and extensive country approvals for global use. Its ability to prevent overloads and optimize power consumption makes it suitable for a wide range of residential and commercial setups.

The MultiPlus-II delivers continuous power suitable for demanding loads, with the added benefit of a built-in uninterruptible power supply (UPS) function. In case of grid failure or disconnection from shore or generator power, the inverter automatically activates within less than 20 milliseconds, ensuring uninterrupted power supply to connected devices like computers and sensitive electronics. This rapid response minimizes data loss and equipment downtime, providing peace of mind during power outages.

Designed for energy storage systems (ESS), the MultiPlus-II can be integrated with MPPT solar chargers or grid-tie PV inverters, enhancing renewable energy utilization. Its external current transformer option supports PowerControl and PowerAssist functions, allowing the system to limit overloads or boost power output as needed, especially when connecting limited AC sources like generators or shore power. This flexibility ensures optimal self-consumption and efficient energy management across diverse applications.

Remote monitoring and control capabilities are a key feature of the MultiPlus-II. When paired with a Victron GX device, such as the Cerbo GX, users can manage their system locally or remotely via the VRM app or website from any location worldwide. This connectivity provides comprehensive control, including adjusting inverter settings, managing backup generator auto-start, and monitoring system performance in real-time, all through smartphones, tablets, or computers. The device's robust design and extensive approvals make it suitable for various countries and applications, ensuring reliable operation in different environments.
