Victron MultiPlus-II 5000W 120V – Ultimate Power for Large Off-Grid Systems
The Victron MultiPlus-II 5000W 120V is the powerhouse inverter/charger designed for serious off-grid, marine, and mobile applications. Delivering a massive 5000 watts of pure sine wave AC output, this unit seamlessly combines a high-capacity inverter, a precision adaptive battery charger, and an ultra-fast automatic transfer switch into one rugged enclosure.
Engineered with PowerAssist technology, the MultiPlus-II ensures you never run out of power by supplementing shore or generator capacity during peak loads. When demand drops, it automatically diverts excess power back into charging your batteries. Whether you’re running a high-demand overland rig, a luxury yacht, or a large off-grid cabin, the MultiPlus-II keeps your power stable, clean, and uninterrupted.
At Autarky Expedition Vehicles in Fallon, NV, we’re more than just a Victron dealer — we’re ABYC-certified installers with years of hands-on field experience. We offer unmatched Victron tech support, competitive pricing, and professional setup guidance so your MultiPlus-II runs at its absolute best from day one.
Key Features:
- 5000W continuous pure sine wave output
- Integrated 4-stage adaptive charger for lithium, AGM, and lead-acid batteries
- PowerAssist boosts shore or generator power during peak demand
- PowerControl prevents overloads by managing battery charging and AC loads intelligently
- Parallel and 3-phase capability for scalable power systems
- Works with Victron GX devices for remote monitoring & control
- Rugged build for marine, RV, and off-grid environments
Perfect For:
Expedition vehicles, large RVs, marine vessels, off-grid homes, and any application demanding reliable high-capacity AC power.
The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid.
It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A).
It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.
Note: for a short period of time this product was called MultiGrid-II.
PowerAssist
The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.
ESS: Energy Storage Systems
The robust MultiPlus-II is the key component in a Victron Energy Storage System. Our new Dynamic ESS feature takes ESS to the next level. It automatically switches between – or combines – grid, battery and solar energy based on live-pricing, predicted energy-use and solar yield so it’s always consuming the cheapest energy.
Uninterrupted AC power (UPS function)
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
Remote Monitoring and Control
When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems’ locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto starting a backup generator and more…
