MultiPlus-II 12/3000 120-50 2X 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 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 MultiPlus-II is the key 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.

Features

• PowerAssist Technology: Prevents overload of limited AC sources by automatically reducing battery charging and boosting generator or shore power output with battery power.

• Advanced ESS Integration: Key component for Victron Energy Storage Systems (ESS), allowing seamless integration with MPPT Solar Chargers and Grid-tie PV Inverters for optimized self-consumption and energy management.

• Uninterrupted AC Power (UPS Function): Automatically activates the inverter in less than 20 milliseconds during grid failures or power loss, ensuring continuous operation of connected equipment.

• External Current Transformer Option: Enables PowerControl and PowerAssist functions with external current sensing (max. 32A) for enhanced system optimization.

• Anti-Islanding Protection: Built-in feature to comply with grid standards and ensure safe operation with a growing list of country approvals.

• Remote Monitoring & Control: Connect with a GX device (e.g., Cerbo GX) for local or remote monitoring and control via the free VRM app and portal. Access and adjust settings from any phone, tablet, laptop, or PC.
