Victron Energy MultiPlus 12/3000/120-50 230V VE.Bus Inverter Charger – PMP123021010

Product Description

The Victron Energy MultiPlus 12/3000/120-50 230V VE.Bus is a powerful combined inverter and battery charger designed for reliable AC power in marine, mobile and off-grid energy systems. With a 12V DC battery input, it delivers up to 3,000VA of pure sine wave AC power and includes a high-capacity 120A battery charger and an integrated 50A AC transfer switch.

Combining inverter, charger and automatic AC changeover functionality in one compact unit, the MultiPlus helps simplify system design while providing dependable power management for demanding installations.

Intelligent Power Management

Victron's PowerControl function allows the AC input current limit to be configured to suit the available mains or generator supply. PowerAssist supplements a limited AC supply with additional power from the battery and inverter when demand temporarily exceeds the configured input limit.

When external AC power is available, the unit can charge the battery and supply connected AC loads. If the AC supply fails, the inverter automatically takes over, helping maintain continuity of power for suitable connected equipment.

Key Features and Benefits

• 3,000VA inverter capacity: Provides up to 2,400W continuous output at 25°C under the specified operating conditions.

• Pure sine wave output: Supplies 230V AC power suitable for a wide range of compatible electrical equipment.

• Integrated 120A battery charger: High-capacity charging for compatible 12V battery systems.

• 50A AC transfer switch: Automatically switches between an external AC source and inverter power.

• PowerControl: Helps prevent overloading a limited mains or generator supply.

• PowerAssist: Supports short periods of higher AC demand by supplementing the external supply with battery power.

• Uninterruptible Power Supply (UPS) functionality: Rapid automatic changeover helps keep suitable equipment operating during an AC supply interruption.

• VE.Bus communication: Supports system configuration, monitoring and compatible parallel or three-phase installations.

• Adaptive charging: Intelligent multi-stage charging helps manage battery charging.

• Integrated protection: Includes protection against overload, short circuit, excessive temperature and battery voltage faults.

Typical Applications

The Victron MultiPlus 12/3000/120-50 is suitable for appropriately designed systems such as:

• Marine electrical systems and boats

• Motorhomes, campervans and expedition vehicles

• Off-grid cabins and remote buildings

• Battery-based backup power systems

• Renewable energy installations using compatible battery storage

• Mobile workshops and specialist vehicle power systems

• Installations requiring inverter power and high-capacity battery charging

Installation and Compatibility

The MultiPlus is designed for integration into a correctly engineered 12V battery-based electrical system. It can operate alongside compatible battery banks, generators, shore power supplies and other Victron Energy equipment.

VE.Bus communication supports system configuration and integration with compatible Victron monitoring and control devices. Multiple compatible units can also be configured for increased power capacity or three-phase operation where the overall system design permits.

Installation should be carried out by a suitably qualified installer. The battery bank, DC cabling, fusing, AC protection, earthing and ventilation must be appropriately rated for the system. At high inverter loads, the DC side can draw very substantial current, so correct cable sizing and battery capability are essential.

Important: This is the 12V MultiPlus model with a 50A transfer switch, not the similar 12/3000/120-16 version with a 16A transfer switch. Check the complete part number before ordering.
