Victron MultiPlus Inverters

Victron MultiPlus & MultiPlus-II Inverter Chargers

Build a highly resilient electrical system for your caravan, motorhome, marine vessel, or off-grid tiny home with a Victron MultiPlus inverter charger. By combining a true sine wave inverter and an advanced battery charger into a single premium enclosure, these units drastically simplify wiring while offering industry-leading reliability. Whether you are running a coffee machine in a 4WD canopy or powering an entire off-grid house, the MultiPlus range delivers continuous, clean power to your most sensitive 240V appliances.

Understanding the MultiPlus Range

The Victron ecosystem offers several variations of this core product to suit different space requirements and power demands. Understanding the differences will help you select the ideal unit for your mobile or static setup.

Victron MultiPlus Compact: Ranging from 500VA to 2000VA in 12V and 24V models, the Compact series is tailored for tight installations in campervans, small caravans, and boats where space is at a premium.

Victron MultiPlus: The standard housing covers a massive range of capacities, including the highly popular Victron MultiPlus 12/3000. These units are the backbone of countless Australian RV and marine power systems, providing robust performance even in demanding high-heat environments.

Victron MultiPlus-II: Also commonly referred to as the Victron MultiPlus 2, this series is optimised for modern Energy Storage Systems (ESS), off-grid, and grid-tied applications. With models like the MultiPlus-II 12/3000/120-32 and powerful 48V options, it features a redesigned enclosure and complies with a wider range of international grid standards. The available GX models feature built-in networking for immediate system monitoring and control.

Key Performance Features

Integrating a Victron MultiPlus into your electrical design unlocks several advanced power management capabilities that standalone units simply cannot match:

• Uninterrupted AC Power (UPS Function): In the event of a grid failure or shore power disconnection, the inverter takes over the supply to connected loads in less than 20 milliseconds, ensuring computers and electronic equipment continue operating without disruption.
• PowerAssist Technology: This unique feature prevents overloading of a limited AC source, such as a generator or caravan park power pedestal. If your load exceeds the input limit, the MultiPlus will automatically supplement the required extra power from your battery bank.
• Highly Scalable Power: Up to six units can operate in parallel to achieve higher power output. Three-phase and split-phase configurations are also fully supported for large-scale commercial and industrial applications.
• System Integration: Seamlessly connect your inverter charger with a monitoring system, such as a Cerbo GX, or use the VE.Bus Smart Bluetooth Dongle to track performance directly from your smartphone.

Sizing or selection tips that help shoppers match products to their setup

Selecting the correct Victron MultiPlus requires matching your battery bank voltage, anticipated AC loads, and required charging current. Victron uses a very specific naming convention to help you identify the right model at a glance. For example, looking at the MultiPlus 12/3000/120-32:

12 indicates the nominal battery voltage. You must match this to your existing or planned system (12V, 24V, or 48V). Using a 48V system reduces cable thickness requirements for high-output models.
3000 represents the inverter's continuous apparent power rating in Volt-Amps (VA) at 25 degrees Celsius. Note that continuous wattage is slightly lower than the VA rating. If you need help calculating your loads, review our guide on understanding inverters and sizing for RVs.
120 is the maximum charge current in Amps delivered back to your batteries when connected to an AC source.
32 denotes the transfer switch capacity. This dictates how much AC current can pass through the unit from a generator or shore power connection to your appliances.

Always ensure your battery bank can handle the substantial DC current draw of a large inverter, and appropriately protect your circuits with high-quality fuses and fuse holders. If you need assistance selecting the proper rating, consult our guide on how to determine the correct fuse for your inverter.
