xVictron MultiPlus 48/3000/35-50 230V VE.Bus Inverter Charger
The Victron MultiPlus 48/3000/35-50 is a combined inverter and battery charger in a single unit, designed for 48V battery systems operating at 230V AC. It is suited to off-grid installations, backup power systems, and marine or vehicle applications where reliable AC output and controlled battery charging are required from one compact device.
Key Features
- 3000VA continuous inverter output at 230V AC from a 48V DC battery bank.
- 35A battery charger built in, with a 50A AC transfer switch for grid or generator input.
- VE.Bus communication interface allows parallel and three-phase configuration with additional MultiPlus units.
- PowerControl function limits the load on the AC input, preventing generator or shore power overload.
- PowerAssist function supplements AC input with battery power during peak demand, allowing a smaller generator or grid connection to be used.
- Adaptive battery charging algorithm adjusts charge profile based on battery behaviour to extend battery life.
- Transfer switch operates in under 20 milliseconds, maintaining supply to connected loads during input switching.
- Compatible with Victron GX devices and VEConfigure software for remote monitoring and configuration.
Product Overview
The MultiPlus 48/3000/35-50 combines a pure sine wave inverter with a multi-stage battery charger. The 3000VA output is continuous, not peak, which matters when sizing for real loads such as pumps, compressors or power tools that draw sustained current. The 48V battery voltage is the preferred choice for larger off-grid systems because it reduces cable losses and allows more usable energy from a given battery bank compared to 12V or 24V configurations.
The VE.Bus interface is central to the unit's flexibility. Up to three MultiPlus units can be wired in parallel to increase output capacity, or configured in a split-phase or three-phase arrangement. This makes the MultiPlus scalable from a single-unit residential backup system through to larger commercial or industrial installations. Configuration is handled via VEConfigure software, and the unit integrates with Victron's GX range (Cerbo GX, Color Control GX) for system monitoring and remote management via the VRM portal.
PowerControl and PowerAssist are practical features for installations with a limited AC supply. PowerControl caps the charger current to avoid tripping a generator or shore power breaker. PowerAssist goes further: when load demand exceeds what the AC input can supply, the inverter draws from the battery to make up the difference. This allows a smaller, more fuel-efficient generator to be used without risking overload trips.

Installation Notes
The MultiPlus 48/3000/35-50 operates at 48V DC and handles significant DC current at full load. Installation must be carried out by a qualified electrician or accredited installer. All DC cabling, fusing and battery connections must be rated appropriately for the system. Where the unit is connected to a grid supply or used as part of a grid-tied or backup system in the UK, compliance with G98 or G99 requirements and notification to the local Distribution Network Operator (DNO) may be required depending on the configuration. VEConfigure software is needed for advanced setup, including charger current limits, PowerControl thresholds and parallel or three-phase configuration.
