Victron Energy MultiPlus-II 24/3000 70-50 2x120V Inverter/Charger (UL458) with PowerAssist and Remote Monitoring

MultiPlus-II 24/3000 70-50 2x120V (UL458)

The MultiPlus-II is a multifunctional inverter/charger with two AC outputs. Suitable for professional marine, yachting, vehicle, and land-based off-grid systems, it also provides the isolation and redundancy required for ESS setups. PowerControl allows the MultiPlus-II to prevent grid or generator overload, while PowerAssist boosts AC power during peak demand. In the event of an outage, the inverter switches over in milliseconds, keeping computers and sensitive electronics running without interruption. The battery charger combines speed with efficiency through a smart adaptive algorithm that extends battery life. Ready for expansion, the MultiPlus-II supports parallel and three-phase configurations when a system needs to scale.

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 robust MultiPlus-II is the key component in a Victron Energy Storage System. Our new Dynamic ESS feature takes ESS to the next level. It automatically switches between - or combines - grid, battery and solar energy based on live-pricing, predicted energy-use and solar yield so its always consuming the cheapest energy.

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

The MultiPlus-II features a robust build suitable for energy storage systems (ESS), allowing integration with solar, grid, and battery sources for optimized energy management. Its dynamic ESS capabilities enable automatic switching between energy sources based on real-time pricing, energy availability, and demand, ensuring the most cost-effective and efficient operation.

This inverter/charger offers PowerControl and PowerAssist functions, which prevent overloads from limited AC sources like generators or shore power. When an overload is imminent, it intelligently reduces battery charging or boosts AC power from the battery to the load, maintaining system stability and performance. In the event of a grid or power failure, the MultiPlus-II seamlessly switches to UPS mode within less than 20 milliseconds, ensuring continuous operation of sensitive electronics and computers without interruption. Its rapid response time makes it ideal for critical applications where power stability is essential.

The MultiPlus-II is equipped with remote monitoring and control capabilities when paired with a Victron GX device, such as the Cerbo GX. Users can access and manage their system remotely via the VRM app or web portal, providing full control over system parameters, auto-start generators, and monitor energy flows from anywhere in the world. The unit supports parallel and three-phase configurations, making it scalable for larger systems. Its compact design and professional-grade features make it a dependable choice for energy systems demanding high performance, redundancy, and flexibility.
