xVictron MultiPlus-II 48/5000/70-50 230V Inverter Charger — PMP482505012
The Victron MultiPlus-II 48/5000/70-50 is a 5000VA inverter charger designed for 48V battery systems operating at 230V AC. It combines a pure sine wave inverter, a battery charger, and an automatic transfer switch in a single unit, making it suited to off-grid installations, backup power systems, and solar storage applications where reliable AC output and controlled battery charging are both required.
Key Features
- 5000VA continuous inverter output with a 48V DC input, delivering 230V AC pure sine wave output.
- 70A battery charger built in, with adaptive charge management to suit a range of battery chemistries including lead-acid and lithium.
- 50A AC input current limit, with PowerControl and PowerAssist functions to prevent overloading a limited AC source such as a generator or shore power connection.
- Integrated transfer switch provides near-instantaneous changeover (less than 20ms) between mains and inverter output, suitable for most sensitive loads.
- Supports parallel and three-phase configurations, allowing multiple units to be combined for higher power or three-phase installations.
- Compatible with Victron VE.Bus communication for system integration, remote monitoring, and configuration via VictronConnect or Venus OS devices.
- Programmable relay and two-signal BMS connection support for battery management system integration.
Product Overview
The MultiPlus-II builds on the established MultiPlus platform with an additional AC input for generator or grid connection, improved BMS communication support, and a wider range of system configuration options. The 48V nominal battery voltage is the standard choice for larger off-grid and hybrid systems, offering lower DC current for a given power level compared to 12V or 24V alternatives, which reduces cable losses and simplifies battery wiring at higher capacities.
PowerAssist is a practical feature for installations where the available AC supply is limited. When load demand exceeds what the AC source can supply alone, the unit draws the shortfall from the battery, preventing generator overload or tripping a shore power breaker. This is particularly useful in marine, vehicle, or remote site installations where generator capacity is fixed. PowerControl performs the same function in reverse, capping AC input draw to a set limit and diverting surplus to charging.
The unit supports parallel operation of up to six identical units for a maximum of 30kVA, and three-phase configurations using three units per phase. This makes it a viable choice for commercial off-grid sites or larger residential installations with three-phase loads. Configuration and firmware updates are handled via VE.Bus using a GX device or the MK3-USB interface.

Installation Notes
The MultiPlus-II 48/5000/70-50 operates at 48V DC and handles significant DC current at full load. Installation must be carried out by a qualified electrician or MCS-accredited installer. All DC cabling, fusing, and battery connections must be sized appropriately for the current involved. For any grid-connected or export-enabled configuration in the UK, compliance with G98 or G99 requirements applies depending on system size and connection type. When integrating with a lithium BMS, use the two-signal BMS port and verify compatibility with your battery system before commissioning. Configuration via VE.Bus requires a GX device (such as a Cerbo GX) or an MK3-USB interface connected to a computer running VictronConnect or VEConfigure.
