xVictron MultiPlus-II 48/3000/35-32 230V Inverter Charger
The Victron MultiPlus-II 48/3000/35-32 is a 3000VA inverter charger designed for 48V battery systems operating at 230V AC. It combines a sine wave inverter, battery charger and transfer switch in a single unit, making it suitable for off-grid installations, backup power systems and solar storage applications where a reliable AC source is required.
Key Features
- 3000VA continuous inverter output with a 48V DC input, suitable for medium-load off-grid and backup systems.
- 35A battery charger with adaptive charge algorithm, compatible with lead-acid and lithium battery chemistries.
- 32A AC input current limit, configurable via VE.Bus to suit generator or shore power sources.
- PowerControl and PowerAssist functions prevent overloading a limited AC source by drawing supplementary power from the battery.
- Near-instant transfer switch (less than 20ms) ensures uninterrupted supply to connected loads during mains failure.
- Supports parallel and three-phase operation when multiple units are configured together.
- Programmable relay and two-signal BMS connection for integration with battery management systems.
- Compatible with Victron VE.Bus, VE.Smart Networking and the GX device ecosystem for full system monitoring and control.
Product Overview
The MultiPlus-II is an evolution of the original MultiPlus, adding a second AC input for generator or grid connection alongside the primary AC input. This allows the unit to manage two separate AC sources independently, which is particularly useful in installations where a generator is used as a backup to grid power. The 35A charger is sized to handle meaningful battery replenishment without requiring an oversized AC supply, and the adaptive charge algorithm adjusts to battery condition over time.
PowerAssist is a practical feature for installations where the available AC supply is limited, such as a small generator or a restricted shore power connection. When load demand exceeds what the AC source can deliver, the unit draws the deficit from the battery bank rather than tripping the supply. This allows a smaller, more economical generator to be used without risk of overload. The 32A input current limit is adjustable, giving installers precise control over how much current is drawn from the source.
The unit supports parallel operation with additional MultiPlus-II units for increased capacity, and can be configured for split-phase or three-phase output. VE.Bus connectivity allows full configuration via VEConfigure software and integration with Victron GX devices such as the Cerbo GX for remote monitoring, system logging and DVCC (Distributed Voltage and Current Control) when used with compatible lithium battery systems.

Installation Notes
The MultiPlus-II must be installed by a qualified electrician familiar with inverter charger systems and applicable wiring regulations. For any grid-connected or grid-backup application in the UK, compliance with G98 or G99 engineering recommendations is required depending on export capacity and connection type. High-voltage 48V battery systems, particularly lithium chemistries, require a suitably qualified installer and a compatible BMS. Configuration should be carried out using Victron's VEConfigure software via a VE.Bus interface. Parallel and three-phase configurations require additional commissioning steps and should only be undertaken by installers experienced with Victron multi-unit setups.
