Introducing the Victron Energy MultiPlus-II 3kVA 48VDC 120VAC Inverter/Charger (Model: PMP482305100)—a cutting-edge solution designed for seamless energy management in residential, marine, and off-grid applications. This versatile unit integrates a powerful inverter, adaptive charger, and advanced energy management features, making it ideal for a wide range of energy needs.

Key Features:

• PowerControl and PowerAssist: Prevents overload on limited AC sources (e.g., generators or shore power) by adjusting battery charging and supplementing power from the battery during peak demand.
• Uninterrupted AC Power (UPS Function): Switches to inverter mode in less than 20 milliseconds during a power outage, ensuring uninterrupted operation of sensitive devices like computers and medical equipment.
• Energy Storage System (ESS) Compatibility: Intelligently manages energy from multiple sources (grid, battery, solar) to optimize self-consumption and prioritize cost-effective energy use.
• Remote Monitoring and Control: When paired with a GX device (e.g., Cerbo GX), offers real-time monitoring and system control via the free VRM app and portal, accessible from anywhere.
• Two AC Outputs: Provides a main output with no-break functionality and a secondary output that is powered only when AC input is available, enabling prioritized load management.
• High Efficiency: Operates with up to 95% efficiency, reducing energy losses and improving overall system performance.
• Robust Design: Compact and lightweight, with a durable construction suitable for residential, marine, and industrial applications.

Product Description:

The MultiPlus-II combines the features of the original MultiPlus and MultiGrid models, offering advanced functionality such as external current transformer support to implement PowerControl and PowerAssist for precise energy management. Its ability to integrate with Energy Storage Systems (ESS) makes it ideal for optimizing self-consumption, reducing reliance on grid power, and increasing solar energy usage efficiency.

During grid failures, the MultiPlus-II instantly activates its inverter to provide uninterrupted power to connected loads. The primary AC output ensures no-break functionality, while the secondary output is activated only when AC input is available, helping to conserve battery energy for critical loads.

Remote monitoring and control capabilities are enhanced with the integration of a GX device, such as the Cerbo GX. Through the VRM app and portal, users can monitor system performance, receive alerts, and make adjustments in real time, offering unparalleled convenience and control.

The MultiPlus-II also features adaptive battery charging technology, which adjusts the charging process based on battery type and usage patterns, ensuring optimal battery health and extended lifespan.
