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.

Features

• PowerAssist Technology:

  • Prevent Overload: Automatically reduces battery charging to prevent overload on limited AC sources like generators or shore power connections.
  • Boost Function: Enhances the output of generators or shore power by using battery power to manage peak loads and prevent overloading.

• Energy Storage Systems (ESS):

  • Flexibility: Acts as a key component in Victron Energy Storage Systems, integrating seamlessly with MPPT Solar Chargers or Grid-tie PV Inverters for efficient energy management.

• Uninterrupted AC Power (UPS Function):

  • Seamless Transition: Automatically activates the inverter in the event of a grid failure or disconnection from shore or generator power, taking over the supply to connected loads in less than 20 milliseconds to ensure continuous operation of sensitive electronic equipment.
