xVictron MultiPlus-II 48/5000/70-50 230V GX — PMP482506000
The Victron MultiPlus-II 48/5000/70-50 230V GX is a 5000VA inverter-charger with an integrated GX controller, designed for off-grid, hybrid and backup power systems running on a 48V battery bank. It combines inverter, charger and system monitoring into a single unit, reducing installation complexity for professional installers working on residential and light commercial projects.
Key Features
- 5000VA continuous inverter output at 230V AC, suitable for demanding loads in off-grid and backup applications.
- 70A battery charger with adaptive charging algorithm, compatible with lead-acid and lithium battery chemistries.
- 50A AC transfer switch for seamless switching between grid, generator and inverter output.
- Integrated GX device (equivalent to a Cerbo GX) provides built-in system monitoring, VRM portal connectivity and DVCC support without requiring a separate controller.
- PowerControl and PowerAssist functions allow the unit to limit grid or generator input current draw and supplement it with battery power when loads exceed the input limit.
- 48V DC input voltage, compatible with 48V lithium (LiFePO4) and lead-acid battery banks.
- Single-phase 230V output, suitable for standard UK and EU grid connections.
- Supports ESS (Energy Storage System) configuration for grid-tied battery storage with self-consumption and feed-in control.
Product Overview
The MultiPlus-II GX differs from the standard MultiPlus-II in one important respect: it incorporates the GX monitoring and control platform directly into the inverter-charger housing. This eliminates the need for a separate Cerbo GX or Venus GX device, which reduces panel space, wiring and overall system cost. The integrated GX connects to the VRM online portal over Ethernet or Wi-Fi, giving installers and end users remote access to system data, alarms and configuration.
The 70A charger is capable of handling bulk charging for larger battery banks without requiring an additional charger. The adaptive charging curve adjusts automatically based on battery type and state, which is particularly relevant when integrating with lithium battery systems that use CAN-bus BMS communication. DVCC (Distributed Voltage and Current Control) is supported, allowing the BMS to govern charge parameters directly through the GX platform.
PowerAssist is a practical feature for installations where the available grid or generator supply is limited. When load demand exceeds the input current limit set by the installer, the unit draws the shortfall from the battery rather than tripping the supply. This is useful in marina berths, campsites, older properties with limited supply capacity, and generator-backed systems where fuel efficiency matters.

- Hybrid solar systems with battery storage, where ESS configuration is used for self-consumption or backup.
- Generator-backed systems where PowerAssist reduces generator run time and fuel consumption.
- Marine and vehicle installations requiring 230V AC output from a 48V battery bank.
- Commercial backup power systems where remote monitoring via VRM is required.
- Installations with limited grid supply capacity where PowerControl prevents supply overload.
What Is Included
- 1 x Victron MultiPlus-II 48/5000/70-50 230V GX inverter-charger unit
Installation Notes
This unit must be installed by a qualified electrician or MCS-accredited installer. The 48V DC connections require correctly rated DC cabling and fusing in accordance with the battery manufacturer's recommendations. For grid-connected ESS installations in the UK, the system must comply with G98 or G99 requirements depending on export capacity, and appropriate DNO notification or approval must be obtained. CAN-bus BMS integration for lithium batteries requires correct network configuration through the GX interface. The integrated GX device requires an Ethernet or Wi-Fi connection for VRM portal access. Due to the unit's weight of 28.3 kg, two-person handling and appropriate wall or rack mounting is required.
