The Victron MultiPlus-II 48/4k5/55-32 GX combines a powerful 48V inverter/charger with an integrated GX device for monitoring and system communication. This makes it a practical solution for installations where reliable AC power, battery charging and remote system monitoring are required.

The integrated display shows battery, inverter and solar charge controller parameters. The same system data can also be accessed via a smartphone, tablet or other Wi-Fi enabled device. For remote monitoring, the unit can be connected to the Victron VRM Portal, allowing system data, performance information and alarms to be viewed remotely.

This model is suitable for off-grid systems, backup power, mobile and marine applications, generator-supported installations and battery energy storage systems. PowerControl and PowerAssist help manage limited AC input from sources such as grid, generator or shore power.
