Inverter Charger | Victron | MultiPlus-II 48/10000/140-100 230V
Product Details
The Victron MultiPlus-II 48/10000/140-100 230V is a compact, all-in-one inverter, battery charger, and automatic transfer switch. Built for 48V battery systems, it delivers 10000VA of continuous AC output and up to 140A of battery charging current from a single AC input. Whether you're powering an off-grid solar system, a caravan, a marine vessel, or a critical backup power installation, the MultiPlus-II handles every scenario with precision. Configure and monitor your system remotely via the VictronConnect app.
Key Features
- PowerAssist: Boosts available shore power or generator output with battery power during peak demand — prevents nuisance tripping on limited supplies.
- UPS-class transfer speed: Switches to inverter in less than 20ms on AC input failure — most sensitive electronics won't notice the interruption.
- Integrated transfer switch: No external changeover relay required — AC input management is built in and fully automatic.
- VE.Bus communication: Connects directly to Cerbo GX, CCGX, and other Victron GX devices for full system monitoring and control.
- Fully programmable: Adjust charge curves, AC input current limits, battery type parameters, and more via VEConfigure software or VictronConnect app.
- Parallel and three-phase capable: Multiple units can be paralleled for higher output, or configured in three-phase for larger installations.

Use Cases
The MultiPlus-II is ideally suited as the central inverter/charger in an off-grid solar system. Combine it with a Victron SmartSolar MPPT charge controller and a Cerbo GX for complete solar-battery management with real-time monitoring via the VRM portal. The adaptive charger automatically adjusts charging current based on available AC supply — maximising battery life and minimising generator run time.
For caravans, motorhomes, and marine vessels, the MultiPlus-II provides seamless transitions between shore power, generator, and battery-only operation. PowerAssist ensures that connecting to a limited shore power supply won't trip breakers when high-draw appliances like air conditioning or a microwave are in use. The compact single-unit design minimises installation complexity and saves valuable space.
As a UPS and backup power solution, the MultiPlus-II provides sub-20ms transfer time from mains to battery — fast enough that connected computers, NAS devices, and sensitive equipment continue operating without interruption. Unlike traditional UPS units, the MultiPlus-II can power heavy loads indefinitely from a properly sized battery bank, making it suitable for telecommunications, medical equipment, and critical business infrastructure.
System Integration
The MultiPlus-II communicates via VE.Bus and integrates seamlessly with the full Victron ecosystem — including Cerbo GX for system monitoring, MPPT solar charge controllers, Smart Shunts, and Lynx busbars. Full system data is accessible remotely via Victron's VRM portal. Multiple units can be configured in parallel or three-phase systems.
