xVictron MultiPlus-II 48/3000/35-32 230V Inverter Charger
The Victron MultiPlus-II 48/3000/35-32 is a combined inverter and battery charger designed for 48V battery systems operating at 230V AC. It is suited to off-grid installations, backup power systems, and solar energy storage applications where a reliable, single-unit inverter charger is required. The integrated transfer switch and PowerAssist function make it a practical choice for both standalone and grid-connected setups.
Key Features
- 3000VA continuous inverter output at 230V AC from a 48V DC battery bank.
- 35A battery charger built in, with adaptive charge algorithm to suit a range of battery chemistries.
- 32A AC input current limit, with PowerAssist to supplement grid or generator supply during peak loads.
- Integrated transfer switch for automatic changeover between mains/generator and inverter operation.
- Two AC outputs: AC-Out-1 remains live during mains failure; AC-Out-2 disconnects when inverting, allowing non-critical loads to be shed.
- Compatible with Victron VE.Bus for system integration, parallel operation, and three-phase configuration.
- Programmable via VictronConnect and Venus OS (GX devices) for remote monitoring and control.
- Supports PowerControl to prevent overloading a limited shore or generator supply.
Product Overview
The MultiPlus-II 48/3000/35-32 combines a pure sine wave inverter with a multi-stage battery charger in a single unit. The 48V DC input voltage is well suited to larger battery banks where lower current draw reduces cable losses and improves overall system efficiency compared to 12V or 24V alternatives. At 3000VA, the unit can handle most household or light commercial loads, including motor starting currents that would trip a lesser inverter.
PowerAssist is a key practical feature for installations where the available grid or generator supply is limited. When load demand exceeds the incoming AC supply, the MultiPlus-II draws the shortfall from the battery rather than tripping the supply breaker. This allows a smaller generator to be used without risk of overload. PowerControl performs a similar function by capping the AC input draw to a user-defined limit, protecting the supply connection.
The VE.Bus interface allows multiple units to be connected in parallel for increased capacity, or configured for split-phase or three-phase output. This makes the MultiPlus-II 48/3000/35-32 a scalable platform for larger installations. Integration with Victron GX devices (such as the Cerbo GX) enables full system monitoring via the VRM portal, including battery state of charge, AC input and output data, and remote firmware updates.

Installation Notes
Installation should be carried out by a qualified electrician or MCS-accredited installer. The MultiPlus-II connects to both a 48V DC battery bank and a 230V AC supply, and incorrect wiring presents a serious risk of electric shock or fire. For grid-connected applications in the UK, compliance with G98 or G99 requirements must be confirmed with your Distribution Network Operator (DNO) before connection. Battery bank sizing, cable ratings, and fusing must be calculated to suit the 35A charge current and the inverter's peak output demands. Programming via VE.Configure or VictronConnect should be completed before commissioning.
