Victron MultiPlus-II 12/3000/120-50 2×120V Inverter Charger | 3,000VA, 2,400W
The 2×120V model accepts and passes through 120/240V split-phase input, but its battery inverter supplies 120V to both output legs. It does not produce 240V from the battery by itself.
Decision facts
- Nominal Battery System: 12V
- Continuous Output at 25°C: 3,000VA / 2,400W
- Maximum Charge Current: 120A
- Transfer Switch: 50A
Victron rates this model 3,000VA and 2,400W continuous at 25°C. Confirm the 2×120V wiring plan and loads.

Frequently Asked Questions
Clear answers to common questions about this product, setup, compatibility, and use.
How much continuous power does the MultiPlus-II 12/3000/120-50 2x120V provide?
Victron rates it at 3,000VA and 2,400W continuous at 25°C, with 5,500W peak power. Output derates at higher temperature, so system design should use watts, temperature, surge demand, and power factor—not the model name alone.
What battery bank does this MultiPlus-II require?
This is the 12V model with a published DC input range of 9.5–17V DC. Battery chemistry, BMS, cables, fuse protection, and charger settings must all be compatible.
How powerful is the built-in battery charger?
The maximum listed charger output is 120A. The actual safe charge current may need to be reduced for the battery bank, BMS, wiring, temperature, and available AC input.
Does the 2x120V model create 240V while inverting?
No. With split-phase shore power present it passes both 120V legs through. In inverter mode it supplies 120V to both legs so 120V loads remain available, but 240V loads are not powered.
What do PowerAssist and the transfer switch do?
The 50A transfer switch passes qualified AC input to loads, while PowerAssist can supplement a limited AC source with inverter power. Configuration and branch protection must match the source, wiring, and connected loads.
Does the MultiPlus-II include Bluetooth?
Not as a built-in direct phone interface. Configuration and monitoring use supported Victron interfaces such as VE.Bus equipment, a GX device, or the appropriate Victron adapter.
