Victron Energy MultiPlus-II 24/3000 70-50 2x120V Inverter/Charger with UPS 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 Victron Energy MultiPlus-II 24/3000 70-50 2x120V inverter/charger is a versatile and reliable power solution designed for professional marine, yachting, vehicle, and off-grid land-based systems. This advanced device combines a powerful inverter and charger in one unit, equipped with two AC outputs to ensure continuous and stable power delivery. Its sophisticated design includes features like PowerControl, which prevents overloads on grid or generator sources, and PowerAssist, which dynamically boosts power during peak demand, ensuring your system maintains optimal performance even under heavy loads. The MultiPlus-II switches seamlessly during power outages in less than 20 milliseconds, providing uninterrupted power to sensitive electronics and critical loads, acting as an uninterruptible power supply (UPS). The integrated battery charger employs a smart adaptive algorithm that extends battery life by balancing charging speed and efficiency, making it suitable for long-term off-grid applications. This model is also ready for expansion, supporting parallel and three-phase configurations, making it adaptable to system growth and increased power demands. Its robust design is ideal for energy storage systems (ESS), with an innovative Dynamic ESS feature that intelligently manages grid, battery, and solar energy based on live energy prices, predicted consumption, and solar yield, ensuring the use of the most cost-effective energy sources. When paired with a Victron GX device like the Cerbo GX, users can remotely monitor and control their system via the VRM app or portal from any location, with full access to system data and control options across multiple devices and operating systems. This product was previously known as MultiGrid-II and is designed for professional and demanding off-grid or grid-tied applications, offering reliable power, smart energy management, and flexible system expansion capabilities.
