Victron MultiPlus-II 48/6500/100-50 Inverter Charger

Victron MultiPlus-II 48/6500/100-50 Inverter Charger

SKU:PMP482605012

Brand: Victron

Industrial Scalability: Connect up to six units in parallel or configure three units for high-output three-phase operation to meet the demands of larger industrial projects. Dynamic ESS Integration: Built-in anti-islanding functionality makes this unit fully compliant for Energy Storage Systems, allowing for automated energy management based on live pricing and yield predictions. Reliable UPS Functionality: Features an ultra-fast switchover time of less than 20 milliseconds, ensuring that sensitive electronic equipment and critical server loads operate without disruption during a grid failure. Optimised Power Management: PowerControl and PowerAssist features prevent grid or generator overloads by prioritising loads and pulling supplementary power from the battery bank during peak demand periods. Flexible AC Distribution: Two separate AC outputs allow for the segregation of critical loads from non-essential equipment, such as water heaters, which should only run when external AC is available. Professional Commissioning: Rapid system configuration and remote monitoring are achieved via VEConfigure software and the VRM portal when coupled with a GX communication device.

Product Details

The Victron MultiPlus-II 48/6500/100-50 Inverter Charger is a heavy-duty inverter charger designed for trade professionals who require a dependable, 48V power hub capable of delivering 6,000 Watts of continuous power at 25°C. This model is particularly suited for professional land-based off-grid systems, yachting, and industrial vehicles that demand high-efficiency energy conversion and sophisticated battery management.
The unit features a 50 Amp transfer switch, allowing it to manage substantial throughput when connected to the grid or a generator. For installers working with limited power sources, the integrated PowerAssist technology is a significant advantage; it enables the system to supplement a generator or shore supply with energy from the battery bank during high peak loads, often allowing for the installation of smaller, more cost-effective generators.

System integration is simplified through the VE.Bus communication port, which supports complex configurations including parallel and three-phase arrangements. The MultiPlus-II is also the primary component for Dynamic Energy Storage Systems (ESS), where it can be programmed to prioritise self-consumption or feed energy back into the grid depending on local regulations and requirements.


For ongoing management, the unit offers comprehensive remote control and monitoring options. When integrated with a Cerbo GX or Ekrano GX, technicians can perform firmware updates, change settings, and troubleshoot systems from any location via the free Victron Remote Management (VRM) portal. The unit is built into a durable steel enclosure with an IP21 rating and is backed by an industry-leading 5-year warranty, providing a reliable long-term solution for professional energy projects.

Functional Features

  • PowerControl & PowerAssist: Dynamically optimizes grid or generator capacity by prioritizing loads and supplementing power from the battery when peak requirements exceed source limits.
  • Dual AC Outputs: The main output provides uninterruptible power (UPS functionality) with a transfer time of less than 20 milliseconds. The second output is live only when AC input is available, ideal for heavy loads like water heaters that should not discharge the battery.
  • Scalability: Supports parallel operation for up to 6 units to increase total power output. Can also be configured for three-phase and parallel three-phase systems.
  • Programmable Relay: Can be configured for general alarms, DC under-voltage warnings, or generator start/stop functions.
  • External Current Sensor (Optional): Supports external sensing (50 A or 100 A) to implement PowerControl and PowerAssist or to optimize self-consumption in grid-parallel topologies.
