Victron MultiPlus-II 48/4k5/55-32 230V

The Victron MultiPlus-II 48/4k5/55-32 is a powerful 48V inverter charger combining a pure sine wave inverter, intelligent battery charger and automatic transfer switch in one unit.

Designed for off-grid, marine and energy storage applications, it provides reliable 230V AC power from a compatible 48V battery bank. It also charges batteries when connected to a suitable mains or generator supply.

Victron MultiPlus-II 48/4k5/55-32 Inverter Charger

The Victron MultiPlus-II 48/4k5/55-32 delivers 4000W of continuous inverter output at 25°C, with 7000W peak power for short-duration demands.

Its pure sine wave output makes it suitable for powering a wide range of compatible 230V appliances and electrical equipment.

Intelligent Battery Charging

The integrated 55A battery charger uses adaptive charging technology to help maintain battery performance.

When connected to a suitable external AC supply, the MultiPlus-II can power connected equipment while charging the battery bank.

PowerAssist and PowerControl

Victron's PowerAssist technology helps prevent limited mains or generator supplies from becoming overloaded.

If electrical demand exceeds the available AC input, the MultiPlus-II can supplement the supply using battery power.

PowerControl allows you to set an AC input current limit, helping manage consumption when using restricted electricity supplies.

Automatic Power Switching

The integrated 32A transfer switch automatically changes between external AC power and inverter operation.

With a fast transfer time, the MultiPlus-II can maintain power to compatible equipment when the external supply is interrupted.

VE.Bus Connectivity and Monitoring

VE.Bus communication allows the MultiPlus-II to integrate with compatible Victron monitoring and control equipment.

When connected to a suitable GX device, such as the Cerbo GX, users can monitor system performance locally or remotely through the Victron Remote Management (VRM) portal.

The MultiPlus-II can also be incorporated into suitably configured Victron Energy Storage Systems (ESS).
