Inverter/charger for marine, mobile, off-grid and backup power systems

The Victron MultiPlus combines pure sine wave inverter, adaptive battery charging and automatic AC transfer functionality in a single unit for marine, mobile, off-grid and grid-connected power systems. PowerControl manages the available generator, shore or grid supply to help prevent the AC source from being overloaded, while PowerAssist can supplement limited incoming AC power with energy from the battery when additional capacity is required. Two AC outputs allow essential loads to remain powered during an interruption, while selected loads can be configured to operate only when an external AC source is available. VE.Bus connectivity supports system integration, remote monitoring, parallel operation and three-phase configurations, with compatibility for lithium-ion battery systems.

Key Features

• Combined inverter and charger: Integrates pure sine wave inverter, adaptive battery charging and automatic AC transfer functions within one system.
• PowerControl: Manages generator, shore or grid input to help prevent the available AC supply from being overloaded.
• PowerAssist: Supplements a limited external AC source with battery power when additional capacity is required.
• Two AC outputs: Maintains power to essential loads through the main output, while the auxiliary output can be used for loads that should operate only when external AC is available.
• VE.Bus connectivity: Supports remote monitoring, system integration, parallel operation and three-phase configurations.
• Expandable system architecture: Multiple compatible MultiPlus units can operate in parallel where greater system capacity is required.
• Lithium battery compatibility: Suitable for integration with compatible lithium-ion battery systems.
• Remote monitoring options: Supports Ekrano GX, Cerbo GX and other GX devices for system monitoring and access to the VRM platform.
• Flexible configuration: Supports stand-alone, off-grid, grid-interactive and self-consumption applications.
• Integrated protection: Includes protection against short circuit, overload, battery overvoltage and undervoltage, excessive temperature, AC voltage on the inverter output and excessive input voltage ripple.
• Durable enclosure: Aluminium construction for installation in protected environments.

Combining power conversion, battery charging and AC source management, the MultiPlus can form the core of integrated Victron energy systems across fixed and mobile applications.
