Victron Energy MultiPlus-II 24/3000 - 70-50 2x120V Multi-Function Power System

MultiPlus-II 24/3000 - 70-50 - 2x120V

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 would occur. 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 key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters.

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 backupgenerator and more"

Note: for a short period of time this product was called MultiGrid-II.

The Victron Energy MultiPlus-II 24/3000 - 70-50 is a versatile power management device designed to seamlessly combine multiple functions for reliable energy solutions. This unit integrates the features of a high-capacity inverter, a charger, and a transfer switch, making it ideal for off-grid, backup power, and energy storage systems. Its compact design offers powerful performance with a focus on flexibility and efficiency, perfect for residential, commercial, or mobile applications.
Equipped with the PowerAssist feature, the MultiPlus-II prevents overloads on limited AC sources such as generators or shore power connections. When an overload is detected, battery charging is automatically reduced to prevent system shutdown, and the device can boost output using stored battery energy to support connected loads. This capability ensures continuous power supply even under challenging conditions, providing peace of mind during power fluctuations or shortages.
The MultiPlus-II also functions as a critical component in Energy Storage Systems (ESS), allowing integration with MPPT solar chargers or grid-tie PV inverters. Its built-in anti-islanding protection complies with multiple country regulations, ensuring safe operation in various regions. Additionally, the device offers an uninterruptible power supply (UPS) function, switching to inverter mode within less than 20 milliseconds during grid failures or disconnection events, safeguarding sensitive electronics and data integrity.
Remote monitoring and control are facilitated through compatibility with Victron GX devices, such as the Cerbo GX. Users can access real-time system status, adjust settings, and manage operations remotely via the free VRM app or web portal. This connectivity enables comprehensive system oversight from any location using smartphones, tablets, or computers, providing maximum convenience and operational control. Please note that this product was previously known as MultiGrid-II for a limited time. For support, repairs, or returns, contact your authorized dealer. Detailed installation and user information are available in the provided owner's manual link.
