Deliver Flexible Split-Phase Power with a 12V 2×120V Inverter and High-Capacity Battery Charger

The Victron MultiPlus-II 12/4k/160-50 2×120V is a multifunction inverter/charger designed for North American split-phase electrical systems used in RVs, marine vessels, off-grid installations and backup power applications. It combines a pure sine wave inverter, 160A battery charger and intelligent transfer switch in a single unit while supporting both 120/240V split-phase and 120V single-phase AC inputs. During inverter operation, both output lines supply 120VAC, ensuring essential 120V loads remain powered while preventing connected 240V appliances from discharging the battery when no split-phase source is available. Advanced PowerAssist and PowerControl technologies maximise available generator or shore power while protecting the AC supply from overload.

Key Features

• Supports 120/240V Split-Phase Systems: Accepts either 120/240V split-phase or 120V single-phase AC input while automatically managing output operation.
• 120VAC Inverter Output: During inverter operation, both L1 and L2 outputs provide 120VAC, allowing all connected 120V circuits to remain operational during an AC outage.
• 3400W Continuous Power Output: Produces 3000VA (3400W) continuous output at 25°C with up to 6kW peak power for demanding applications.
• 160A Integrated Battery Charger: High-capacity charger rapidly replenishes 12V battery banks from generator or shore power.
• PowerAssist and PowerControl: Supplements limited AC supplies with battery power during peak demand while preventing overload of generators or shore connections.
• Dual AC Outputs: Primary output supplies uninterrupted power to essential loads, while the auxiliary output operates only when external AC is available.
• Fast Transfer Switching: L1 transfers to inverter operation in less than 18 milliseconds, helping maintain operation of sensitive electronic equipment.
• Expandable Power System: Supports parallel operation with up to six units and can be configured for three-phase systems where required.
• Advanced Monitoring and Remote Management: Compatible with Cerbo GX, Ekrano GX, VictronConnect and the Victron VRM Portal for system configuration and remote monitoring.
• VE.Bus Communication: Provides integration with Victron energy systems, battery management systems and remote monitoring solutions.

The MultiPlus-II 12/4k/160-50 2×120V provides intelligent power conversion and battery charging for split-phase electrical systems while maintaining seamless operation of essential 120V loads during power interruptions. Its scalable architecture and advanced energy management make it suitable for demanding mobile and stationary power installations.
