Victron Energy MultiPlus 48/2000/25-50 120V VE.Bus Inverter/Charger – PMP482200100

Product Overview

The Victron Energy MultiPlus 48/2000/25-50 120V VE.Bus is a versatile inverter/charger designed to provide reliable AC power from a 48V battery system. Combining a pure sine wave inverter, an intelligent battery charger and an automatic transfer switch in one compact unit, it offers an integrated power solution for off-grid installations, marine applications, mobile power systems and backup electricity.

With a 2,000VA inverter capacity, the MultiPlus converts 48V DC battery power into 120V AC electricity for compatible appliances and equipment. When connected to a suitable AC power source, such as a generator or shore supply, the integrated charger replenishes the battery bank while the transfer switch automatically changes between external AC power and inverter power as required.

Inverter Performance and Power Supply

The MultiPlus produces a pure sine wave AC output, making it suitable for a wide range of compatible electrical equipment. Its 48V DC input supports installations designed around higher-voltage battery banks, helping reduce DC current compared with equivalent lower-voltage systems.

The 2,000VA inverter is designed to handle everyday electrical loads within its operating limits. Actual usable power depends on factors including the load's power factor, ambient temperature, ventilation and the battery system's ability to deliver sufficient current.

Integrated Battery Charger

The built-in 25A battery charger provides controlled charging from an available AC supply. Victron's adaptive charging technology adjusts the charging process to suit the battery's condition and charging requirements, helping support efficient battery charging when configured for the installed battery type.

Correct battery settings, appropriate protection and suitable cabling are essential. Always configure the charger for the battery manufacturer's recommended charging profile.

Automatic AC Transfer Switch

The integrated 50A transfer switch allows the unit to switch between an external AC supply and inverter-generated electricity. When acceptable external power is available, the MultiPlus can pass that supply through to supported loads and charge the battery. If the external source becomes unavailable, it can change to inverter operation to help maintain the power supply to connected equipment.

PowerControl and PowerAssist

PowerControl helps limit the current drawn from a restricted AC source, which is useful when operating from a small generator or limited shore-power connection. PowerAssist can supplement the available AC supply with energy from the battery when demand temporarily exceeds the configured input-current limit, subject to the system's operating and power limits.

These functions can help manage available power more effectively in installations where the incoming AC supply has limited capacity.

VE.Bus System Integration

The VE.Bus communication interface allows the MultiPlus to be configured and monitored using compatible Victron equipment and software. It also supports integration into suitable multi-unit systems, including parallel or three-phase arrangements where the complete system design and selected equipment permit.

Compatible monitoring and control equipment can provide greater visibility of system operation and allow configuration to suit the installation.

Applications

The Victron Energy MultiPlus 48/2000/25-50 120V is suitable for compatible marine electrical systems, boats using 120V AC equipment, specialist mobile installations, remote cabins and off-grid power systems designed around 48V batteries. It can also be used in backup-power installations where the inverter capacity, AC voltage and transfer-switch rating meet the requirements of the connected loads.

This model produces 120V AC, so it should be selected for systems designed for that voltage rather than assumed to be a direct replacement for a 230V UK or European model.
