Description
xVictron MultiPlus-II 24/3000/70-32 230V Inverter Charger
The Victron MultiPlus-II 24/3000/70-32 is a combined inverter and battery charger designed for 24V battery systems. It delivers 3000VA of continuous inverter output and a 70A battery charger, with a 32A AC transfer switch built in. It is suited to off-grid installations, backup power systems, and mobile or marine applications where a single, integrated unit is required.
Key Features
- 3000VA continuous inverter output with 24V DC input, producing 230V AC output.
- 70A multi-stage battery charger with adaptive charge algorithm to suit a range of battery chemistries.
- 32A AC transfer switch with a transfer time of less than 20 milliseconds, maintaining supply to connected loads during grid or generator transitions.
- PowerAssist function allows the unit to supplement shore power or generator output, preventing overload of the AC source.
- Two AC outputs: AC-Out-1 remains live during inverter operation; AC-Out-2 disconnects when running on battery, allowing non-essential loads to be shed automatically.
- VE.Bus communication port for system integration, parallel operation, and configuration via Victron GX devices or VEConfigure software.
- Compatible with Victron Venus OS and the GX range for full remote monitoring and control.
- Supports parallel and three-phase configuration when multiple units are used together.
Product Overview
The MultiPlus-II combines a true sine wave inverter, a battery charger, and an AC transfer switch in a single enclosure. The 24V input voltage makes it appropriate for systems where a 24V battery bank is preferred, typically mid-sized off-grid or backup installations. The 3000VA output is sufficient for most domestic or light commercial loads, and the 70A charger can handle a substantial battery bank without requiring a separate charging unit.
The PowerAssist feature is particularly useful where the available AC input (from shore power or a generator) is limited. The unit monitors the incoming current and, when loads approach the set limit, draws additional power from the battery to make up the difference. This prevents nuisance tripping of breakers or overloading of small generators. The 32A transfer switch rating aligns with standard single-phase supply ratings in the UK and EU.
VE.Bus connectivity allows multiple MultiPlus-II units to be configured in parallel for increased output current, or in split- or three-phase arrangements for three-phase loads. Configuration is carried out using Victron's VEConfigure software or, where a GX device is present, via the Victron Remote Management portal. This makes the unit suitable for scalable installations where future expansion may be required.

Installation Notes
The MultiPlus-II must be installed by a qualified electrician or accredited installer. DC wiring to the battery bank must be correctly rated for the current involved, and appropriate fusing must be fitted on the DC side. For any grid-connected application in the UK, compliance with G98 or G99 (depending on export capacity and connection type) is required, and the relevant network operator notification or approval process must be followed. Battery chemistry must be correctly configured in the unit before commissioning. For lithium battery installations, ensure the battery management system is correctly integrated via the VE.Bus or an appropriate relay signal. Do not attempt installation without appropriate electrical qualifications.
