Introducing the Victron Energy MultiPlus 12/3000/120-50 120V VE.Bus (UL)—a versatile inverter and charger designed to provide reliable power for various applications, including RVs, marine environments, and off-grid systems. This compact and efficient unit combines a true sine wave inverter with an adaptive battery charger, ensuring seamless power management and uninterrupted AC supply for sensitive electronics and appliances.

Key Features:

• PowerAssist Technology: Prevents overloads on limited AC sources (e.g., generators or shore power) by supplementing power with energy from the battery. This feature ensures that all connected devices operate without interruptions, even during peak demand.
• Uninterrupted AC Power (UPS Function): In case of a grid failure or disconnection from shore or generator power, the inverter activates within 20 milliseconds, maintaining stable power to sensitive electronics, such as medical devices and computers, that require an uninterrupted supply.
• Parallel and Three-Phase Operation: Supports parallel operation of up to six units, enabling higher output power. It can also be configured for three-phase or split-phase setups, offering flexibility to meet diverse power requirements in both residential and commercial applications.
• Remote Monitoring and Control: When paired with a GX device (e.g., Cerbo GX), users can monitor and control the system locally or remotely via the internet using the free VRM app and portal, ensuring complete control and flexibility.

Product Overview:

The MultiPlus 12/3000/120-50 120V VE.Bus (UL) is a comprehensive power solution, delivering 3000 VA of continuous power with a 6000W peak output, making it ideal for powering sensitive electronics and heavy-duty appliances. The adaptive 120A battery charger adjusts its charging process based on the battery's condition, optimizing battery life and performance.

One of the standout features is PowerAssist Technology, which temporarily draws power from the battery to boost the output during peak demands, preventing overloads when connected to limited AC sources like generators or shore power.

In the event of a power failure, the MultiPlus instantly switches to inverter mode within 20 milliseconds, ensuring that sensitive devices continue to operate without disruption.

For systems requiring higher power output, the MultiPlus can be configured for parallel operation of up to six units, delivering a combined output of up to 18 kVA. Additionally, it supports three-phase or split-phase operation, providing the flexibility to meet varying power needs.

Remote monitoring through the VRM app and portal is facilitated when the MultiPlus is paired with a GX device, such as the Cerbo GX. This allows users to monitor performance, adjust settings, and view real-time data from anywhere, making it ideal for off-grid installations or locations with remote access.
