Victron Energy MultiPlus-II 12/3000/120-50 120V (UL 458) — 3000 VA 12V Inverter Charger for North American 50A Split-Phase RV, Marine and Off-Grid Systems
The Victron Energy MultiPlus-II 12/3000/120-50 120V (UL 458) (EAN: 8719076049289) is a powerful inverter charger purpose-built for the North American market and marine applications. It combines a pure sine wave inverter of 3000 VA with a 120A adaptive battery charger in a single compact enclosure, making it the ideal solution for RVs, campers, boats and off-grid systems requiring 50A split-phase shore power compatibility.
Technical specifications
- Continuous output power: 3000 VA / 2400 W at 25°C
- DC input voltage: 12 V
- Battery charger: 120 A adaptive, compatible with LiFePO4, lead-acid, AGM and gel
- AC input/output: 120V / 2x 120V (50A split-phase)
- Transfer switch: 50 A with switchover time of less than 20 milliseconds
- Certification: UL 458 and UL 1741
- Communication: VE.Bus, compatible with VictronConnect and VRM
Intelligent 2x 120V split-phase functionality
When connected to 50A shore power or a generator, both lines (L1 and L2) are passed through for full power utilisation. On a single-phase 120V supply, both output lines are combined so that both sides of your distribution panel remain powered at all times. In inverter mode, 120V is delivered across both output lines simultaneously.
Energy management and protection
- PowerControl prevents overload of shore power or generator
- PowerAssist automatically supplements available AC power with battery energy during peak demand
- Built-in anti-islanding function for safe grid-tied operation
- UPS function: switchover in less than 20 ms during power failure
Scalable and remotely manageable
- Up to 6 units connectable in parallel for higher output
- Monitoring via VRM portal and GX devices (Cerbo GX, Ekrano GX)
- Configuration via VictronConnect app or VEConfigure software
Installation and use
Connect the DC side to your 12V battery bank and the 50A split-phase AC input to shore power or a generator. Configure via the VictronConnect app. UL 458 certification ensures safe, reliable operation in all mobile and marine environments.
